How to find the age of your Kenmore dishwasher

Where to find the model and serial number on your dishwasher

Start by locating the model and serial number label on your Kenmore dishwasher. On most models, both numbers appear together on the same label.

Common locations include:

• Along the inner door frame

• On the tub wall near the door opening

• On the side or top edge of the door

The model number usually starts with three digits, followed by a period and additional numbers. Those first three digits determine which serial number format you’ll use to find the production date.

If your dishwasher’s model number starts with 363

Kenmore dishwashers with model numbers starting with 363 use a serial number format where the production date is encoded at the start of the serial number using letters.

The serial number typically begins with two letters:

First letter = month

Second letter = year

This format provides the month and year the dishwasher was built.

Because letter codes repeat over time, you may still need to confirm the decade using the dishwasher’s design and features.

Choosing the correct year

Because the year letter cycles over time, the serial number alone may point to more than one possible year. Use the dishwasher’s control style, features, and overall design to determine which year makes sense.

For model numbers beginning with 587

Kenmore dishwashers with model numbers starting with 587 typically use a serial number format where the production date appears near the beginning of the serial number.

Common serial number format

YWWxxxxx

• First digit = last digit of the year

• Next two digits = week of production

Example:

A serial number beginning with 923 indicates a dishwasher built in week 23 of a year ending in 9.

Because only the last digit of the year is shown, you’ll need to use the dishwasher’s features, controls, and styling to determine the correct decade.

If the model number starts with 630

Kenmore dishwashers with model numbers starting with 630 use a serial number format that includes an FD code, which identifies the production date.

Where to find the FD code

The FD code appears near the serial number and starts with the letters **FD**, followed by a series of numbers.

How to read the FD code

The production date is encoded in the numbers immediately following “FD.” The first digit indicates the decade; the 2^nd digit is the year within the decade; and the 3^rd and 4^th digits indicate the month of production. The decade digit does not directly match the decade itself; for example, a code starting FD7712xxx doesn't mean the dishwasher was made in the 1970's.

Decade code reference

Month code reference

Examples:

• FD7711xxxx → November 1997

• FD9708xxxx → August 2017

• FD9805xxxx → May 2018

After decoding the FD code, make sure the production date lines up with the dishwasher’s design, controls, and features.

For Kenmore dishwashers starting with 665

Kenmore dishwashers with model numbers starting with 665 use a serial number format where the production date is encoded near the beginning of the serial number.

Start by looking at the first four or five characters.

Common serial number format for 665 dishwashers

LLYWWxxxxx or LYWWxxxxx

• First one or two letters = production location

• Next character = year

• Next two digits = week of production

The year is shown as a single character. That character represents a year ending in that value, and the pattern repeats every 30 years.

Examples:

RA01xxxx = was made in the first week of either 1991 or 2021.

FM644xxxx = was made in the 44th week of either 1986 or 2016.

Choosing the correct year

Because the year code repeats every 30 years, use the dishwasher’s design, controls, and features to determine which decade makes the most sense.

If your model number begins with 722

Kenmore dishwashers with model numbers starting with 722 typically use a serial number format where the production date appears at the beginning of the serial number.

YMMxxxxx

• First digit = last digit of the year

• Next two digits = month

Example:

A serial number starting with 908 indicates a dishwasher built in August of a year ending in 8.

Use the dishwasher’s design and controls to confirm the correct decade.

Confirm the age before repairing or replacing

Once you’ve decoded the production date, take a moment to make sure it lines up with the dishwasher’s condition.

Helpful cross-checks include:

• Whether the age fits the dishwasher’s control layout and features

• Whether the estimated timeframe matches the model series

• Whether wear, labeling, and design details align with that era

If something doesn’t add up, revisit the serial number format before making a repair or replacement decision.
