Step-by-Step Guide: Decipher Your Whirlpool Water Heater’s Serial Number for Age

Determining the age of your Whirlpool water heater is crucial for planning maintenance, repairs, and replacements. Understanding the serial number system can help you unlock this information effortlessly.

Serial Number Location

Locate the serial number on the data plate attached to the water heater. It typically consists of a combination of letters and numbers.

Whirlpool Serial Number Format

Whirlpool serial numbers follow a specific format that varies depending on the manufacturing year.

Pre-2011

Serial numbers before 2011 begin with a letter followed by a six-digit number. The letter indicates the manufacturing year, while the numbers represent the production sequence.

Example: A012345

2011-2019

From 2011 to 2019, serial numbers start with two letters followed by a seven-digit number. The first letter indicates the manufacturing year, while the second letter represents the month of production.

Example: BA1234567

2020-Present

Serial numbers manufactured from 2020 onwards follow a similar format but include an additional letter at the end. The first letter indicates the manufacturing year, the second letter represents the month of production, and the third letter signifies the production plant.

Example: CAB1234567A
