Introduction
Dishwashers are designed to remain connected to a household’s water, drain, and electrical systems, but they may need to be stored temporarily during a renovation, move, remodel, or property closure. Knowing how to store a dishwasher properly can prevent frozen hoses, trapped water, corrosion, damaged doors, electrical hazards, and costly problems when the appliance is reinstalled.
The safest storage method depends on whether the dishwasher is built in, freestanding, connected to a shutoff valve, or hardwired. No single approach suits every home, so the most important rule is to follow the manufacturer’s instructions whenever they differ from general guidance.
This guide explains how to prepare a dishwasher for short- or long-term storage, how to move it safely, which storage location to choose, and how to troubleshoot the appliance before and after it is returned to service.

Choose the Right Storage Plan
Before touching any connection, decide how long the dishwasher will be out of service and whether it will remain in the kitchen. A dishwasher being covered during flooring or cabinet work for several days needs a different preparation than one being packed for a move or stored in a vacant home for several months.
Short-Term Kitchen Storage
If the dishwasher will be disconnected but remain under the counter, the goal is to protect it from construction debris, dust, paint, and accidental impact. It should be completely empty and dry before panels or doors are covered.
For a built-in model, do not remove the door unless the cabinet or countertop work requires it. Removing and reinstalling the door can damage hinges, clips, seals, and the decorative panel. Secure the appliance to the cabinet with temporary screws if the manufacturer permits it.
Long-Term or Off-Site Storage
For long-term storage, the dishwasher should be disconnected, drained, thoroughly dried, and moved upright to a clean, dry, climate-controlled location whenever possible. Basements, garages, sheds, and vacant properties can experience condensation, temperature swings, pests, or flooding.
Do not leave a disconnected dishwasher in place if construction work could expose it to water, heavy materials, or impact. The appliance may be safer in a protected storage area, but moving it can also create risks. A qualified appliance technician can help if the installation is complex.
Prepare Before Disconnecting
Preparation reduces the chance of flooding, electrical shock, or damage to the dishwasher and surrounding cabinets. Start by checking the appliance for leaks, corrosion, damaged hoses, loose doors, and unusual noises. If the dishwasher is already malfunctioning, record the symptoms before disconnecting it.
Empty the appliance completely. Remove dishes, utensils, racks, baskets, detergent, rinse aid, and any filters or accessories that can be stored separately. If the manual allows removable racks to be removed, wrap them loosely in moving blankets or cardboard rather than sealing wet or sharp components inside the appliance.
Place towels or a shallow plastic container beneath the connections. Depending on the local plumbing setup, you may also need a wet/dry vacuum, bucket, adjustable wrench, flat screwdriver, pliers, and work gloves. Do not rely on a bucket alone when draining a dishwasher because hoses can retain water.
Find the appliance’s model and serial number before beginning. These details help locate the correct manual and replacement parts later. Photograph the installed configuration, including hose routing, wiring locations, bracket positions, and door orientation.
Never remove a connection while the dishwasher is energized. If the power, water, or drain connection is difficult to identify, stop and consult the manual or a licensed plumber or electrician.
Step-by-Step Storage Instructions
Follow these general steps when learning how to store a dishwasher safely. The exact order can vary by model, especially if the appliance has an air gap, garbage disposal, unusual hose arrangement, or concealed connections.
- Turn off the power. If the dishwasher uses a plug, unplug it from the receptacle. If it is hardwired, switch off the appropriate household circuit breaker and confirm that the power is off before touching the wiring. Follow the manufacturer’s electrical instructions.
- Close the water supply. Use the hot-water shutoff valve under the sink, if one is present. If there is no local valve, identify the household main shutoff before starting. Do not force a stuck valve.
- Disconnect the water inlet. Place a towel or container beneath the connection and slowly loosen the compression nut or fitting. Cap or plug the exposed line to help prevent debris from entering it.
- Disconnect the drain hose. Depending on the installation, the hose may connect to a disposal, standpipe, air-gap fitting, or another appliance. Open the dishwasher door and remove any hose clamp if required, then drain remaining water into a suitable container.
- Remove installation hardware. Take out mounting screws, brackets, trim pieces, kickplates, or other fasteners only if the appliance will be moved or cabinet access requires them. Bag the hardware and label its location.
- Pull the dishwasher out carefully. If it remains in the cabinet, protect the floor and cabinet edges. When pulling it forward, avoid catching the door, hoses, wiring, flooring, or adjacent cabinets.
- Drain and dry the interior. Remove standing water from the sump and hoses, clean the filters, and let the door and racks air-dry. For moisture trapped inside a hose, disconnect it and hold it in a position that allows water to drain out.
- Secure loose parts. Close the door, engage any shipping or appliance locks supplied with the dishwasher, and tie hoses loosely so they cannot tangle. Do not wrap hoses so tightly that their shape is permanently distorted.
- Protect the exterior. If the dishwasher is exposed to dust, wrap it in clean moving blankets or breathable protective material. Keep the appliance upright and avoid placing heavy objects against the door or control panel.
- Move and store it upright. Put the appliance in a clean, dry location away from chemicals, moisture, sunlight, pests, and traffic. If transportation is required, secure it to an appliance dolly and use straps without compressing vulnerable components.
Do not operate the drying fan after disconnecting the dishwasher from electrical power. Leaving the door open may help air out a short-term installation, but it does not make an off-site storage location moisture-proof.
How to Move a Dishwasher Safely
A dishwasher is heavy, awkward, and vulnerable to bending. Most residential models weigh approximately 75 to 150 pounds or more, and the actual weight can differ substantially by model. Moving it alone can cause back injuries, cabinet damage, and broken internal components.
Use an appliance dolly with a strap rated for the dishwasher’s weight. Place the appliance upright, secure the door, protect the exterior with moving blankets, and keep hoses and cords clear of the dolly’s wheels. Two capable adults may be needed to guide the appliance and navigate steps.
Upright movement is generally the safest option. If a dishwasher must be laid on its side because of a tight doorway or transport configuration, consult the manufacturer first. Some models allow limited side transport, but others can suffer damaged door rollers, insulation, drainage components, or electronics.
After unavoidable side transport, return the appliance to its upright position and let it stand for the period specified in its manual. That waiting period is not a substitute for inspecting for leaks or damaged hoses. Never move a dishwasher while it is full of dishes, water, or detergent.
For stairs, narrow stairs, heavy built-in models, or installations involving hardwired electricity, hire professionals. The cost of appliance moving is often much lower than repairing damaged cabinetry, flooring, plumbing, or an injured worker.
Compare Dishwasher Storage Methods
The best storage method balances time out of service, exposure to the environment, and the difficulty of moving the appliance. Consider the table below before choosing a location.
| Storage method | Best for | Main advantages | Key cautions |
|---|---|---|---|
| Connected in the kitchen | Brief flooring, paint, or cabinet projects | Avoids removal and reinstallation | Connections and cabinetry remain exposed; water and debris can cause damage |
| Disconnected under the counter | Short renovations lasting days or weeks | The appliance stays protected within its normal location | Requires careful capping, drying, fastening, and floor protection |
| Upright in a dry indoor area | Long-term household or project storage | Lower moisture and impact risk than a garage or shed | Must be protected from dust, traffic, chemicals, and accidental operation |
| Garage or shed | Storage where no better indoor area is available | More space and easy access | Condensation, temperature changes, pests, and leaks can damage the appliance |
| Professional transport | Moving homes, long-distance storage, or difficult access | Correct lifting and secure transport reduce damage risk | Coordinate reconnection and inspect the appliance before installation |
Special Considerations for Built-In Models
A built-in dishwasher is normally supported by surrounding cabinetry and attached to the countertop, floor, or side panels. Unlike a portable unit, it cannot always be rolled away and returned to service without a major reinstallation process.
Before removal, shut off the household water supply if there is no dedicated under-sink valve. Disconnect power only as described in the installation manual. Photograph all brackets and connections so the appliance can later be restored to its original position.
Do not remove the outer door unless necessary. On many models, the door is part of the cabinet’s structural support or carries decorative panels that are difficult to remove without damage. If door removal is necessary, the manual should explain how to transfer the inner panel, control strip, wiring, and door latch safely.
The cabinet opening should be covered only with a material that will not block airflow and will not be mistaken for a work surface. Protect nearby cabinets, floor, countertop, and plumbing openings from dust and debris. Do not place a load on any part of the dishwasher or its door.
A built-in dishwasher stored in an empty house may need extra care against condensation, especially in humid regions. A breathable cover placed over a dry appliance is generally safer than wrapping it tightly in plastic, which can trap moisture.
Prevent Rust, Odors, and Water Damage
The most common storage damage begins with residual moisture. Even a small amount of water inside a hose, sump, filter, or control area can create odors or corrosion if the dishwasher remains idle for months.
After draining, wipe the interior, door seals, racks, and under-door area dry. Leave the dishwasher open briefly in a ventilated room while you are still working nearby. Remove the filters and any removable spray arms for separate cleaning, then reinstall or store them according to the manufacturer’s instructions.
Inspect hoses and seals for cracks, bulges, stiffness, corrosion, or damp patches. Replace visibly deteriorated parts rather than relying on tape, glue, or temporary clamps. If a water line has been disconnected for an extended period, have the plumber cap it correctly; an open or improvised plumbing connection can leak when the property is reoccupied.
Keep the storage area free from gasoline, solvents, fertilizers, pool chemicals, paint thinner, and corrosive cleaning products. Pets may chew hoses or enter an open appliance. Rodents can nest in warm cavities, so seal the surrounding storage space without blocking the dishwasher’s inspection points.
For a detached dishwasher, use a dedicated appliance cover or clean moving blankets. Avoid plastic sheeting pressed tightly against the appliance, and never secure a cover with screws or nails that could puncture the outer tub.
Returning a Stored Dishwasher to Service
Do not assume that time alone makes the dishwasher ready to operate. Before reconnecting it, inspect the appliance and installation from the beginning of the water line to the drain.
Flush or clear the newly opened water line according to the plumber’s instructions. Replace washers in fittings when appropriate, inspect the connector for damage, and avoid over-tightening plumbing joints. Reconnect the inlet hose without kinks and route it according to the manufacturer’s high-loop, low-loop, or other approved arrangement.
Install a new or sound hose clamp on the drain connection. A miniature stainless-steel clamp may resist corrosion better than a zinc-plated screw clamp. Confirm that the drain hose reaches the disposal or standpipe without creating a high loop that can hold dirty water.
Restore the correct mounting brackets, trim panels, kickplate, and door hardware. The dishwasher should be securely anchored without being compressed in a way that distorts the tub or prevents the door from opening fully.
Restore electrical power and run the dishwasher empty on a short rinse or fill-and-drain cycle when the manual permits. Stay nearby for the first cycle. Watch beneath the cabinet, around the door seal, at the hose connections, and beneath the appliance for leaks. Cancel the cycle or switch off power if water appears where it should not.
During the first few cycles, check that the door latches, racks roll properly, spray arms rotate, filters seat correctly, drainage works, and unusual grinding or rattling sounds are absent. Remove any detergent residue or construction dust before loading dishes.
Storage and Reinstallation Troubleshooting
Water Leaks After Reconnection
If water appears under the dishwasher, first stop the cycle and turn off power if necessary. The most common causes include a loose inlet fitting, worn hose clamp, damaged seal, incorrectly seated filter, loose door, or improperly secured mounting bracket. Dry the area completely, restore power only when it is safe, and run a brief empty test while watching the suspected connection.
Dishwasher Will Not Start
A dishwasher that was stored but did not move may be electrically locked, inadequately supplied, or still protected by a shipping feature. Check that the breaker is on, the plug or junction cover is secure, the door is fully latched, and the control panel is responding. Avoid removing a control panel or opening an electrical junction unless you have the appropriate knowledge and the manual permits it.
Poor Draining or Water in the Sump
A small amount of water in the bottom is normal in many models, but standing water that grows after a cycle usually indicates a blocked filter, pump, drain hose, air gap, disposal, or plumbing problem. Clean the filter as directed by the manufacturer and confirm that the drain hose is not kinked, crushed, frozen, or blocked. Stored hoses should never be bent tightly enough to retain water.
Musty or Chemical Odor
An odor generally means moisture, detergent residue, food debris, mold, or stagnant water remained inside. Empty the appliance, remove and clean the filters, wipe the door seals and tub, and ventilate the interior. Avoid mixing bleach with ammonia, acids, or other cleaners. If the smell continues, inspect the drain and sump for hidden debris.
Grinding, Rattling, or Stuck Racks
Storage pressure, moving damage, or transport on the wrong side can affect wheels, rollers, spray arms, door hinges, and internal brackets. Remove and inspect the racks according to the manual. Roll them by hand and look for bent wheels or debris. Do not force a jammed rack; repeated force can enlarge the damage.
Storage Tips and Best Practices
- Read the manual first. Model-specific instructions take priority over general storage advice, especially for portable, compact, countertop, smart, or panel-ready dishwashers.
- Create an installation record. Photograph the hoses, wiring, brackets, leveling legs, and door before disconnection. Label removable parts and place screws in a sealed bag.
- Keep the appliance upright. Upright storage reduces the chance that water, door rollers, detergent ports, or internal components will be damaged.
- Use a climate-controlled location. Dry, conditioned indoor space is preferable to an unfinished garage, damp basement, or shed.
- Protect without sealing in moisture. Use clean moving blankets or a fitted appliance cover rather than airtight plastic wrap.
- Keep the dishwasher empty. Dishes, utensils, baskets, and detergent can break, trap moisture, or obstruct the door.
- Address plumbing immediately. Cap or protect open water lines and have them inspected if the dishwasher will be offline for a long period.
- Inspect before energizing. Check the cord, wiring area, water lines, drain hose, and installation hardware for damage caused by moisture, pests, or impact.
- Test without dishes first. A short empty cycle can reveal leaks and basic operation before valuable kitchenware is placed inside.
- Schedule reinstallation early. After renovations or moves, arrange plumbing and electrical help promptly instead of leaving a disconnected appliance in storage.
Common Mistakes to Avoid
The first common mistake is assuming that switching off the dishwasher controls disconnects it from power or water. Appliance controls do not necessarily isolate the electrical supply, and a closed faucet may not drain water already trapped in hoses. Shut off the actual supply and use the correct breaker or disconnect method.
Another mistake is pulling a built-in dishwasher out by the door. The door and front panel may not be designed to support the appliance’s weight. This can bend the rails, break the latch, or damage cabinetry. Support the dishwasher as it moves and follow the manual’s handling instructions.
Do not lay the dishwasher on its side merely to make moving easier. If side transport is unavoidable, verify that the model permits it, protect the appliance, and follow the required settling period. Do not place it face down, upside down, or with heavy items resting against the door.
Leaving the appliance closed and damp is also a mistake. Moisture can become trapped around the door gasket, tub, and hoses. Clean and dry the interior, check for residue, and allow air circulation before moving it to storage.
Finally, do not tighten plumbing fittings aggressively or use improvised materials for a long-term repair. Over-tightening can damage threads and fittings, while tape or glue can fail when the appliance is used. Replace worn washers, hoses, and clamps with suitable parts, and use a plumber or electrician when the installation requires professional work.
Frequently Asked Questions
Can a dishwasher be stored for a year?
Yes, a dishwasher can be stored for a year or longer if it is properly disconnected, cleaned, dried, covered, and kept in suitable conditions. A dry, climate-controlled indoor location is best. Perform a full inspection before reconnecting it because hoses, seals, wiring, and plumbing may have deteriorated.
Can I store a dishwasher on its side?
Prefer not to store it on its side. Upright storage protects internal components, wheels, door hardware, and drainage passages. If side transport is unavoidable, consult the manufacturer, protect the appliance, and keep it upright for the manual’s recommended settling period before testing it.
Do I need to disconnect a dishwasher before replacing flooring?
Not always, but disconnecting and moving it may prevent water, tools, debris, and heavy flooring materials from damaging the appliance. If the flooring project is short and the manufacturer allows the dishwasher to remain in place, protect it carefully. Turn off water and power if there is any risk of flooding or work-related damage.
Does turning off the dishwasher turn off its power?
No. Turning off a control panel or selecting a cycle does not disconnect a dishwasher from household electricity. Unplug the appliance or switch off its dedicated circuit breaker before working on it, following the appliance and electrical instructions.
Can I store a dishwasher in a garage?
A garage is not ideal because condensation, temperature changes, pests, vehicle chemicals, and roof leaks can damage a dishwasher. If no better location exists, keep it upright, fully dry, protected from the elements, and away from chemicals. Use a suitable cover and inspect it periodically for moisture or corrosion.
How do I remove a smell from a dishwasher after storage?
Remove all dishes and accessories, clean the filters and removable spray components, and wipe the tub, door seals, and door edges. Let the appliance dry with the door open in a ventilated area. Persistent smells may indicate trapped water, mold, a blocked drain, or contaminated hoses and may require deeper service.
Conclusion
Knowing how to store a dishwasher is largely a matter of controlling water, movement, and exposure. Disconnect the correct electrical and plumbing supplies, empty the appliance, drain and dry the hoses and interior, protect loose parts, and keep the dishwasher upright in a clean, dry location.
Built-in units deserve extra caution because removing or reinstalling them can damage cabinetry and connections. Photograph the original setup, follow the model’s manual, and use professional help when lifting, hardwiring, or plumbing work would be unsafe.
Before returning the appliance to service, inspect every connection, replace deteriorated components, secure the mounting hardware, and complete a short empty test. With careful preparation and a thorough reinstallation check, a correctly stored dishwasher can be returned to reliable operation without avoidable water damage or repair costs.
