Whirlpool dishwasher smells bad inside
A sour or mouldy smell when the door is opened. These are the Whirlpool part numbers we hold for the components that cause it, with the number of models each one is listed against.
Before you order anything
- Clean the filter and the sump area — food trapped there is the usual source.
- Run a hot cycle with the filter removed and check whether the smell returns within a week.
- If it returns, the drain pump housing is holding water; that is when a part replacement is justified.

This is a diagnostic starting point built from the parts listed for Whirlpool dishwashers,
not a service manual. Confirm the model plate inside the door before ordering: one character changes the part.
