Electrolux Dishwasher Error Code Er 03

Er 03 on an Electrolux dishwasher means the control board has detected that the wash pump is not operating. The wash pump is responsible for circulating water through the spray arms during the wash cycle, and without it the cycle cannot proceed. The error can be caused by a jammed impeller, a failed motor, wiring issues, or a faulty control board.

No, the dishwasher will not complete a wash cycle when Er 03 is active because the wash pump is not functioning. Continuing to run the appliance in this condition will not damage it further in most cases, but the dishes will not be washed. It is best to resolve the error before attempting further use.

A reset may temporarily clear the error code, but if the underlying problem with the wash pump has not been resolved, the code will return as soon as the dishwasher attempts to run the pump again. Resetting is useful as a first step to rule out a temporary electronic glitch, but a persistent Er 03 requires physical inspection and diagnosis of the pump and its circuit.

Some causes of Er 03 are DIY-friendly, particularly clearing a jammed pump impeller by accessing the pump through the filter area at the bottom of the tub. However, electrical repairs such as replacing the pump motor, capacitor, or control board involve working with wiring and require basic electrical testing tools like a multimeter. If you are not comfortable with electrical diagnostics, a qualified technician is recommended.

Repair costs vary depending on the root cause. Clearing a jammed impeller yourself costs nothing beyond your time. A replacement wash pump motor typically runs between $75 and $200 for the part alone, with professional labor adding $100 to $200 depending on your location. Control board replacement is generally the most expensive option, with parts ranging from $150 to $350 or more.
