Equator Dishwasher Error Code E5

E5 on an Equator dishwasher signals a short circuit or broken circuit in the water temperature sensor. The control board monitors the sensor's resistance continuously, and when values fall outside the acceptable range or no signal is detected, it displays E5 and stops the cycle. The fault can be in the sensor itself or in the wiring connecting it to the control board.

It is not recommended to continue running the dishwasher with an E5 error active. Without a functioning temperature sensor, the control board cannot accurately regulate water heating, which could lead to overheating or inadequate sanitization. The appliance will typically halt the cycle when E5 is detected, which is a protective measure you should respect.

A power reset by unplugging the unit or cycling the breaker may temporarily clear the E5 display, but the error will return as soon as the dishwasher attempts to read the temperature sensor again. The underlying fault in the sensor or wiring must be diagnosed and repaired to permanently resolve the error code.

A confident DIYer with a multimeter can diagnose this error by testing the temperature sensor for continuity and resistance. If the sensor reads open or shorted, replacing it is a straightforward repair involving disconnecting the wiring connector and unclipping or unscrewing the sensor from the sump area. If wiring damage is found, repairing or replacing the harness section is also manageable for someone comfortable working with appliance wiring.

If only the temperature sensor needs replacement, the part itself typically costs in the range of $15 to $40 depending on the specific model. If professional labor is involved, total repair costs including the part and service call can range from $80 to $180. Wiring harness repairs or a control board replacement would increase costs considerably.
