Error code Er03
Appliance Dishwasher
Affected model series EIDW6105, EIDW5905
Quick answer

Electrolux dishwasher code Er03 indicates wash pump not operating.

Model compatibility: Electrolux reuses codes across series and control generations, so Er03 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

When Er03 appears on your Electrolux dishwasher, it indicates wash pump not operating. Model and control-platform context matters before any part is condemned. Use the observed symptoms and the full model number to confirm the correct diagnostic path.

Treat this number as a diagnostic pointer rather than a parts verdict: wash pump not operating. The visible behavior matters: spray action may stop can occur with wash or drain motor problem, but blocked pump path remains another documented possibility.

This code is documented in Electrolux EIDW6105/EIDW5905 service data. Confirm the exact model before applying this diagnostic path.

Before you call

Safe checks you can make

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

  • Turn the dishwasher off for several minutes.
  • Clean accessible filters and remove visible debris from the sump.
  • Confirm the drain hose is not blocked.
  • Try one short cycle after the reset.

Important safety warning. Stop if a motor hums without moving water, smells hot, or trips the breaker.

When to call a technician

A recurring Er03 motor code needs internal pump, wiring, and control diagnosis.

For a repeat Er03, share the model and the behavior you saw, especially whether spray action may stop. Professional testing can then confirm or rule out wash or drain motor problem.
