Whirlpool Dishwasher Error Code E5

The E5 code indicates an NTC open circuit failure, meaning the water temperature sensor circuit has a complete break in its electrical path. The control board cannot receive any temperature data from the sensor. This causes the dishwasher to stop normal operation because it cannot safely control the heating system without valid temperature feedback.

You should not continue running the dishwasher while the E5 code is active. Without a functioning temperature sensor, the control board cannot properly regulate the heating element, which creates a risk of overheating or incomplete sanitization of dishes. It is best to address the fault before using the appliance again.

Resetting the dishwasher may temporarily clear the E5 code from the display, but the fault will return as soon as the control board attempts to read the temperature sensor again. Because E5 indicates a physical open circuit in the sensor or its wiring, the underlying hardware problem must be repaired before the code will stay clear permanently.

A knowledgeable DIYer can diagnose this fault by visually inspecting the sensor wiring, checking for loose or corroded connectors, and testing the NTC thermistor for continuity with a multimeter. If the sensor has failed internally, replacing it is generally straightforward once the dishwasher is safely disconnected from power. If the wiring harness or control board is the problem, the repair may require more technical skill.

If the NTC thermistor itself is the problem, the part is relatively inexpensive, typically in the range of $15 to $50 depending on the specific model. If a technician is needed for diagnosis and replacement, labor costs will add to that figure, bringing total repair costs to roughly $80 to $200. A control board replacement, if required, will cost significantly more.
