Temperature sensor (NTC) fault

Unplug the dishwasher and access the sump/heater area from the base
Locate the NTC temperature sensor near the flow-through heater
Measure the sensor resistance cold — an open or near-zero reading indicates failure
Inspect the sensor connector for corrosion from long-term moisture exposure
Replace the NTC sensor if out of range and reseat a clean connector
Pro Diagnostic Tip
Because the NTC sits in the humid sump, a green-corroded connector pin is a more common E05 cause than the sensor itself — clean and reseat before replacing.
