Kenmore Dishwasher Error Code E2

E2 indicates an NTC temperature sensor error. The control board is receiving a resistance reading from the NTC thermistor that falls outside the acceptable range, which prevents the dishwasher from accurately monitoring water temperature. The fault can stem from the sensor itself, the orange wire harness connecting it, or the control board.

Running the dishwasher with an active E2 error is not recommended. Without reliable temperature feedback, the control board cannot properly regulate the heating element, which could result in inadequate cleaning, overheating, or further component damage. The issue should be diagnosed and corrected before resuming normal use.

Repair costs vary depending on the faulty component. An NTC thermistor is generally an inexpensive part, with DIY repair costs typically ranging from around 10 to 40 dollars for the sensor alone. If a control board replacement is required, parts and labor can range from 150 to 350 dollars or more depending on the model and service provider.

Start by measuring resistance across the two orange wires connected to the NTC sensor and compare that reading to the NTC resistance chart for your model. If the resistance is out of range, replace the NTC thermistor. If the sensor reads correctly, inspect the orange wire harness and connectors for damage or corrosion and repair as needed before suspecting the control board.

A power reset may temporarily clear the E2 code, but the error will return if the underlying fault in the NTC sensor or wiring has not been repaired. A reset is useful for confirming whether the fault is intermittent, but it is not a fix on its own.
