How do I know if my wash pump motor is failing?

Common signs include dishes not getting clean, the dishwasher making unusual loud noises like grinding or buzzing during the wash cycle, or a complete lack of water circulating through the spray arms. Sometimes, the dishwasher may run its cycle but fail to properly wash the dishes due to a non-functioning pump.

Is it safe to run my dishwasher with a failing wash pump motor?

It is generally not recommended to run a dishwasher with a known failing wash pump motor. Continuing to operate it could lead to further damage to other components, potential leaks, or simply ineffective cleaning, wasting water and energy. It's best to address the issue promptly.

What causes a wash pump motor to fail?

Wash pump motors can fail due to several reasons, including normal wear and tear over time, electrical issues, or physical obstructions. Hard water deposits can also contribute to impeller damage or motor seizure. Foreign objects like broken glass or food debris can also get lodged, causing damage.
