I have a Kenmore Elite dishwasher (model 665.13153K701) and wanted to know its exact age using the serial number. If you’re trying to figure out when your dishwasher was made, it’s actually pretty simple once you know how to read the serial.
Quick Answer
Your Kenmore Elite dishwasher (SER FW3829040) was manufactured in September 2008, which makes it about 17–18 years old today.
Step-by-Step: How to Determine Dishwasher Age
Step 1: Identify the Serial Number Format
Kenmore (made by Whirlpool) uses coded serial numbers.
- Your serial: FW3829040
- The key part is the first two letters + first digits
Step 2: Decode the Manufacturer Code
For Whirlpool-built Kenmore models:
- First letter (F) = Manufacturing plant
- Second letter (W) = Year code
- Next two digits (38) = Week of the year
👉 “38” = 38th week of the year
Step 3: Convert Week to Month
Week 38 falls around:
- September (late Q3)
👉 That’s how we get September 2008 as the production date.
Step 4: Calculate Current Age
From September 2008 to now:
- Approximately 17–18 years old
👉 That’s well beyond the typical dishwasher lifespan.
Extra Tips and Best Practices
- Average dishwasher lifespan: 8–12 years
- Older units may:
- Use more water and energy
- Have worn seals and components
- Consider replacement if repairs become frequent
Common Mistakes to Avoid
- Confusing model number with serial number
- Ignoring manufacturer (Kenmore = often Whirlpool)
- Misreading the week/year code
