How old is my Whirlpool dishwasher?

1. Find the rating label: With the door open, on the left side of the tub frame. Double-drawer models carry it on the right side of the upper drawer.
2. Take a photo of the whole label, or note the model and serial numbers.
3. Check it on Appliance Age. It is free, and no account is needed.

With the door open, on the left side of the tub frame. Double-drawer models carry it on the right side of the upper drawer.

Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable date.

Use the format that belongs to this product family. A printed production date, a supported serial code or manufacturer confirmation can establish the age. Repeating year codes may leave more than one possible year; a model-series introduction date helps narrow the range but does not date your individual unit.

Dishwashers typically last 9 to 12 years. Use, water quality and maintenance matter more than the brand. Clean the filter at the bottom of the tub every month to keep it draining and cleaning well.

11 Whirlpool models are currently ENERGY STAR certified, 8 of them sold in Canada. The certified models went on the market between 2023 and 2026. An older Whirlpool dishwasher may use more energy than today's certified models.

Find the rating label (With the door open, on the left side of the tub frame.
