Haier Dishwasher Error Code E3
Water not heating to temperature
Common Causes
- 1Failed flow-through heating element
- 2Open or drifted NTC temperature sensor
- 3Control board heater relay fault
- 4Corroded element wiring connection
Step-by-Step Troubleshooting
- 1
Run a hot cycle and feel the door glass late in the wash, since a Haier dishwasher that never warms points at the sump heater rather than the sensor
- 2
Unplug the unit and measure the flow-through heating element resistance at its terminals, treating an open reading as a failed element
- 3
Check the NTC sensor resistance against its rated curve and replace it if the value sits far off at room temperature
- 4
Inspect the element spade connectors under the base for heat discolouration that raises resistance and stops the water heating
- 5
If the element and sensor both test good, the board heater relay is not closing and the control board needs attention
Pro Diagnostic Tip
On Haier dishwashers the heater and wash pump share the sump module, so an E3 that appears with weak wash pressure is often a scaled-up sump restricting flow across the element rather than a dead element.
