What Er 03 Means
Er 03 is the wash pump code, described by Electrolux as a dead wash motor. The control is not getting the current or response it expects from the wash pump.
Common Causes of Er 03
- Wash motor failed
- Impeller jammed
- Wash motor wiring open
🔧 One Safe Check You Can Try
Clean the filter and check the sump for debris that could jam the impeller, then reset at the breaker.
⚠ Why You Shouldn't Go Further Than That
- The wash motor is under the tub.
- Replacement requires the dishwasher to be pulled out.
