E01
Heating circuit fault
What causes it
Failed heating element or thermostat.
What it means in practice
The dishwasher can't heat its water as expected. A failed heating element or thermostat is the typical cause.
What to check before calling
- ✓Power-cycle the dishwasher at the breaker.
- ✓This usually points to a failed heating element — not a DIY repair.
- ✓Run a short cycle and feel whether the water or dishes get warm.
- ✓Check that the machine's power supply and breaker are fine.
When to call a technician
If water isn't heating, the heating element or thermostat needs testing.
If those checks don't clear the E01 code, it's usually a sign of a failed part rather than something to keep resetting. A technician runs a full diagnostic on your dishwasher, confirms the cause, and quotes the repair before any work starts. The $89 service call is waived if you go ahead with the repair, and parts and labor are covered by our 90-day warranty on parts & labor.
Common question
Will dishes still get clean?
Poorly. Without heat, detergent works less well and drying suffers.
Still showing E01?
