Affected model seriesEIDW6105, EIDW5905
Quick answer
Electrolux dishwasher code Er02 indicates thermistor or turbidity-module problem detected.
Model compatibility: Electrolux reuses codes across series and control generations, so Er02 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
Electrolux dishwasher code Er02 points to thermistor or turbidity-module problem detected. The display narrows the diagnostic path, but it does not prove which component should be replaced. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
This display is most useful when it is paired with the model number and observed behavior: thermistor or turbidity-module problem detected. If you also notice cycle timing may be abnormal, compare that observation with thermistor issue before assuming turbidity sensor/module issue.
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 the filters and sump so heavy debris is not affecting operation.
Restore power and try one cycle.
Do not access internal sensors yourself.
Important safety warning. Stop if the code returns after one reset.

When to call a technician
Sensor and wiring tests for Er02 require access to internal components, so recurring errors should be diagnosed professionally.
When booking for Er02, note the full model number and whether cycle timing may be abnormal. A model-specific diagnosis can then concentrate on thermistor issue without replacing parts by guesswork.
Seeing this code on your Electrolux appliance?
If the code returns after the safe checks, book a repair visit and share the exact display plus your full model number.
Electrolux Dishwasher Repair for common Electrolux problems, safe troubleshooting, error-code context, and signs it is time to schedule professional service.
It indicates thermistor or turbidity-module problem detected. Confirm the full model number because Electrolux diagnostic meanings can vary between control platforms.
You can try the safe external checks on this page and one power reset when appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
One test cycle after a reset is reasonable if there is no leak or overheating. A returning sensor code needs service.
