Introduction
Finding the production year of a Kenmore dishwasher usually comes down to locating its model number and serial number. The model number identifies the appliance’s product family, size, features, and configuration, while the serial number is more likely to connect it with manufacturing records. However, the exact meaning of a Kenmore serial number depends on the company that built the appliance and the numbering format used in that year.
Kenmore dishwashers have been manufactured by several brands, including Whirlpool, KitchenAid, Frigidaire, and other appliance companies. Because these manufacturers use different labeling locations and date-code systems, there is no single place or code format that works for every model. Knowing what year was my Kenmore dishwasher made therefore requires a short identification and lookup process rather than a guess based only on the model’s age or purchase date.
Quick Answer: What Year Was My Kenmore Dishwasher Made?
In most cases, you can estimate or determine the year by reading the appliance identification label inside the dishwasher’s door area and using the full model and serial numbers in the manufacturer’s product database. Some serial-number systems reveal a production month and year, while others identify only a production period. Older appliances may require archived documentation or assistance from the manufacturer, parts department, or an appliance repair company.
A model number alone usually cannot tell you when a particular unit was manufactured. For example, the same Kenmore model may have remained on sale for several years. A serial number is more unit-specific, but you should not assume every group of characters represents a date unless the format matches the manufacturer’s records for that production period.
To get the best answer, record every character in both numbers, identify the actual manufacturer, and check the information in this order:
- Read the model and serial numbers from the appliance.
- Identify the company that manufactured the Kenmore product.
- Use the current or archived manufacturer lookup for that brand.
- Confirm any decoded date with a second reliable source.
- Keep a record of the result for maintenance, parts, warranty, or resale purposes.
Where to Find Your Kenmore Model and Serial Numbers
The best location for the identification information is usually inside the front door opening, near the lower edge or side wall. The label may be printed directly on the appliance, stamped into metal, or placed on a silver, white, or black data plate. You may need to remove the lower rack, shine a flashlight at an angle, or clean the area before reading the characters.
Common label locations include:
- Inside the left or right side wall of the door opening
- Along the lower front edge of the door
- On the inner door frame near the latch
- On the front or side of the dishwasher tub
- On a paper label attached beneath the rack track
- On the back or underside of the door in some portable or commercial-style models
Do not confuse the serial number with nearby specifications such as voltage, amperage, water pressure, model codes, service information, or a “S/U/P” production code. The serial number is usually a longer string of letters and numbers and is often labeled explicitly as Serial No., S/N, or Serial Number. The model number may appear as Model No., Type, or simply P/N.
Take a clear photograph of the label or copy both numbers exactly. A blurred 0 can be confused with the letter O, and a 1 can look like an I. An incorrect character may lead to an unrelated model, an invalid serial number, or a production date that is several years off.
Step-by-Step Guide to Finding the Production Year
Follow these steps to answer the question “What year was my Kenmore dishwasher made?” with the most reliable information available.
- Make the identification information readable. Empty the lower rack and look inside the front opening. Clean the label if necessary, but do not scrape it aggressively. Use a flashlight held at an angle to make stamped characters easier to see.
- Record the complete model number. Copy every letter, number, and decimal without guessing. Model identifiers commonly begin with 110 for Kenmore appliances, but the remainder identifies the specific dishwasher family and configuration.
- Record the complete serial number. Do not shorten the serial to its first or last few characters. A manufacturer may need the full identifier to distinguish your unit from a different production run.
- Find the manufacturing company. Look for Whirlpool, KitchenAid, Frigidaire, or another manufacturer on the label, installation manual, control panel, or packaging. Kenmore was sold by Sears, but many Kenmore dishwashers were built by another company.
- Open the official product information for the manufacturer. Search using the full model number rather than a general term such as “Kenmore dishwasher.” The results should lead to specification pages, manuals, parts diagrams, or a serial-number tool.
- Enter the serial number if the manufacturer offers a lookup. Record whether the result provides an exact date, month and year, quarter, production sequence, or broad manufacturing period. These levels of precision are not equivalent.
- Check an archived date-code method only if it applies to your brand. A serial format may include an encoded date, but character positions and lookup formulas can differ by manufacturer and production era. Do not apply a random online formula to a Kenmore model without confirming its origin.
- Cross-check the result. Compare the reported date with the model’s availability period, the appearance of the label, maintenance history, and any receipt or service documentation. An apparent contradiction is a reason to verify the numbers, not to average the answers.
- Save the result for future use. Write down the manufacturer, model, serial number, date range, source, and date checked. This is useful when ordering replacement parts, requesting a manual, planning repairs, or listing a used appliance.
What the Kenmore Model Number Tells You
A Kenmore dishwasher model number describes a specific product configuration. It can tell you the nominal capacity, tub or rack design, control type, operating features, voltage, and other model-specific details. It may also show when that product family was introduced or sold, but that is not necessarily the year your individual dishwasher was produced.
Most conventional Kenmore dishwashers use a model number beginning with 110. The remaining characters usually narrow down the machine. If the number consists only of a small number of characters, the appliance may be an older model for which online records are limited. A longer model number does not automatically mean the dishwasher is newer; both model formats and naming systems have changed over time.
Use the model number to obtain a manual or parts diagram, verify the product’s general era, and determine the manufacturer. Do not use it alone as proof of a production year. Two dishwashers with identical model numbers can be manufactured months or years apart.
How Kenmore Serial Numbers May Reveal a Date
Many appliance manufacturers include production information in the serial number, but there is no universal Kenmore date-code formula. Whirlpool-built, KitchenAid-built, and Frigidaire-built dishwashers may use different structures. The exact format can also change between product families or periods.
When a manufacturer’s documentation confirms that particular characters represent the year and week or month, the serial can lead to a fairly precise answer. The final characters, however, are often used as a sequence number and should not automatically be interpreted as a date. A valid-looking group of letters and numbers may have no date information at all. (See Also:How To Clean Your Dishwasher)
Be especially cautious with third-party decoder charts. A chart written for Whirlpool cabinet refrigerators, washing machines, or a different appliance category may not apply to a Whirlpool-built dishwasher. The same company can use different number lengths and coding systems over time. Apply a decoder only when the manufacturer, appliance type, serial length, and production era all match.
The safest result is one supported by an official model page, a manufacturer service department, a manufacturer parts representative, or reliable archived service documentation. If a decoder identifies a week, treat the result as a production estimate until you can corroborate it.
How to Use an Official Date or Serial Lookup
An official lookup is generally the most efficient route because it can associate the model with the correct manufacturer and production system. Start with the brand named on the data plate, not necessarily the Kenmore name displayed on the controls.
For Whirlpool-built models, use Whirlpool’s appliance identification and parts resources. For KitchenAid-built models, use KitchenAid’s service and product information resources. For Frigidaire-built models, use Frigidaire or its parent company’s identification tools. The exact tool availability may change as older appliance records are archived.
When a lookup works, note the exact wording of the result. “Produced in 2011” is more precise than “model year 2011,” while “manufactured between 2012 and 2015” provides a range. Some systems return a “production start date” for a model generation rather than the date of your individual appliance.
If no result appears, confirm that the serial number was copied without spaces or substitutions. Then search the model number by itself to verify the product category and manufacturing brand. If the serial is not recognized, continue with the model and archival resources described below.
Worked Examples of Identifying the Year
These examples illustrate how the evidence should be interpreted without assuming that every serial number follows the same formula.
Example 1: The serial decoder provides a month and year
You locate a Kenmore model number and serial number, confirm from the label that the dishwasher was built by Whirlpool, and find a Whirlpool documentation page that covers that serial format. The decoder identifies a year and production week. Because the format, manufacturer, and appliance category match, the result may indicate production in 2014 during a specified week. Save the documentation and consider contacting a parts representative if you need confirmation for a specific component.
Example 2: The database provides only a range
A manufacturer tool recognizes the model but reports that units matching the serial prefix were produced from early 2018 through mid-2019. It does not identify a day or month for your individual dishwasher. The accurate conclusion is that it was manufactured within that range, not that it was necessarily made in 2018 or 2019 alone.
Example 3: Only the model is available
An older listing shows that your Kenmore model was introduced in 2006 and remained available for several years. Your receipt says the appliance was purchased in 2011, while the seller says it came from a home built in 2013. Neither fact proves the production year. The best conclusion is an approximate range based on the model’s sales period, pending an archival serial lookup or manufacturer assistance.
Example 4: The receipt and service records conflict
Suppose a purchase receipt is dated 2015, but an earlier service invoice includes the serial number and is dated 2012. The service invoice is stronger evidence that the machine existed by 2012, but the receipt may refer to a resale, warranty claim, accessory, or another transaction. Compare the appliance identification number on every document and ask the retailer or service company to clarify the records.
Comparing Methods for Determining the Production Year
| Source or method | What it can establish | Main limitation | Relative reliability |
|---|---|---|---|
| Manufacturer serial lookup | A unit-specific date, production period, or recognized serial range | Older units may be outside the current database | Best when the model and serial match |
| Manufacturer product or model page | Product specifications, manufacturer, model era, and related documentation | Often shows a model year or availability range rather than the exact unit date | High for identification |
| Serial decoding chart | An encoded year, month, or week | Incorrect or outdated charts can produce dates that are years off | Useful only when the format matches |
| Parts catalog or diagram | Confirmation of the model, manufacturer, compatible parts, and production family | May cover several model years at once | High for model identification |
| Service company or parts representative | Decoded production information and access to archived records | A verbal or written estimate may depend on database availability | High when records are available |
| Purchase receipt | Approximate time the appliance entered the seller’s records | It is not always the manufacture date, especially for used units | Supporting evidence only |
| Home age or seller memory | A rough estimate of the appliance’s era | Remodeling, storage, inherited appliances, and delayed sales can make it inaccurate | Low |
Using Manuals, Service Records, and Production Documentation
If a current online lookup cannot find an older dishwasher, search for the model’s installation or service manual. Archived documentation may identify the actual manufacturer, provide a parts list, or explain the number series used during a particular period. The back cover or first page of the manual is often more useful than a general search result because it ties the document directly to your model.
Service invoices can also establish a minimum date. If a repair company documented work on your exact serial number in 2009, the dishwasher existed by 2009. That does not necessarily identify its production year, but it is more reliable than an owner’s vague memory. Warranty registrations, shipping receipts, and original dealer paperwork may provide similar supporting evidence.
For a precise archival answer, contact the service or parts department of the identified manufacturer. Provide the complete model and serial numbers in one message, along with a clear image of the data plate. Ask which production field was used, what date range the records show, and whether the result is a decoded estimate or a unit-specific manufacturing record.

What to Do If the Serial Number Is Missing or Unreadable
Start by looking again in less obvious locations, especially the door frame, rack supports, and lower edge. Older labels may be hidden beneath mineral deposits, adhesive, or a loose mounting bracket. A flashlight, magnifying glass, and careful cleaning may expose additional characters without requiring panel removal.
If the serial remains unreadable, record the model number and every other visible code. A manufacturer parts representative can use those details to identify the production family and estimate the supported year range. A matching parts diagram can also reveal whether the model was sold in a narrow period, although it still may not date one specific dishwasher.
Search original manuals and archived dealer documents using the model number. Avoid removing control panels or cutting labels without first considering damage and safety. If you obtain a different appliance or door during a repair, preserve any data plate attached to the removed part because the replacement part may not carry the original serial information.
When no reliable source remains, state the result as a range based on the model’s documented availability. That is more accurate than presenting the purchase year, receipt year, or an arbitrary decoder result as an exact manufacturing date.
Tips and Best Practices for a Reliable Answer
- Photograph the complete label. Save a close image showing every character and the manufacturer’s name for future reference.
- Use the actual manufacturer first. The Kenmore name identifies the product line, while Whirlpool, KitchenAid, or Frigidaire may control the production records.
- Search the complete model without dashes. Some directories index only one punctuation format.
- Confirm the serial-number length before decoding. Do not add or remove leading zeros to make a number match a website’s format.
- Record the precision of the answer. Save an exact week, month, year, or range exactly as the source reports it.
- Cross-check the model era. A decoded date should generally fall within the period when the model was produced and sold.
- Keep documentation with the appliance. A small record of the model, serial, manufacture date, manuals, and maintenance history makes future service easier.
Common Mistakes and Problems to Avoid
The most common error is treating the model’s first three digits as a date. A Kenmore model number beginning with 110 identifies a product category and numbering system; it does not mean the appliance was manufactured in 1910. Another mistake is assuming the final serial digits form a month and year. Those characters may simply identify production sequence within a daily, weekly, or monthly batch.
Applying a Whirlpool decoder to a Frigidaire-built dishwasher can also produce a confident but incorrect result. Check the actual manufacturer before using any formula. Likewise, do not trust an SEO decoder site that does not identify its source, coding system, appliance category, and update history.
Do not use the dishwasher’s purchase date as its manufacture date. Appliances may sit in inventory, remain in storage, or be sold years after production. Warranty registration dates are closer to the beginning of ownership and can be affected by late registration, resales, or original purchaser errors.
Finally, do not rely on appearance alone. Kitchen design, control panels, racks, and interior finishes can look similar across several years. The model and serial labels provide the strongest evidence for determining when the appliance was made.
Frequently Asked Questions
Can I find the exact year from the model number alone?
Usually, not with certainty. A model number identifies a product family that may have been manufactured over several months or years. It can establish an approximate era, and a model page may provide a “model year,” but only a unit-specific serial record or a valid manufacturer date-code system can establish when your dishwasher was produced.
Is there one Kenmore serial-number date formula?
No single formula applies to every Kenmore dishwasher. Kenmore was sold by Sears, but many models were manufactured by other companies, each with its own serial conventions. A decoder must match the actual manufacturer, appliance type, serial length, and production period. Verify the result against official documentation whenever possible. (See Also:How To Use Frigidaire Dishwasher Old Model 2)
Does a Kenmore dishwasher model number starting with 110 mean it is old?
No. The 110 prefix is part of the Kenmore appliance numbering system and does not represent a year. The rest of the model number and the serial number provide the useful age clues. Many modern Kenmore dishwashers also begin with 110, so the prefix alone cannot determine whether an appliance is recent or discontinued.
Does the warranty or purchase date equal the manufacture date?
Not necessarily. The warranty period may begin at purchase, delivery, or manufacture depending on the company and appliance, while the registration date records when the owner submitted information. A receipt proves a transaction, not necessarily production. Use these dates as supporting evidence and prioritize the model and serial data.
What should I do if the online serial lookup cannot find my dishwasher?
Verify the manufacturer and each character, then search using only the model number to confirm the product family. If the appliance is older, locate an archived manual, parts diagram, or service document. A manufacturer’s parts or service representative may be able to search legacy records and provide a production year or range.
How old should I assume an unrecognized Kenmore dishwasher is?
Do not assign an age merely because the serial search failed. The model’s documented production period, physical design, documentation, and service history can establish a range. If reliable evidence is unavailable, call it an approximate model-era estimate rather than a confirmed manufacture year.
Conclusion
To determine what year a Kenmore dishwasher was made, locate the model and serial numbers inside the door opening, identify the company that manufactured it, and use the most authoritative lookup or archived documentation available. The model number establishes the product family; the serial number provides the better chance of finding a production date, although the result may be a month, week, or multi-year range.
Read every character carefully, avoid generic serial decoders, and distinguish manufacture year from model year, purchase year, and warranty date. If the dishwasher is too old for an online database, a model-based estimate combined with manuals, parts records, and service evidence will provide the most dependable answer possible.
