GE Dishwasher Error Code F26

F26 means the control board has detected a faulty thermal cut out (TCO) inside one of the dishwasher motors, either the circulation motor or the drain motor. The TCO is a built-in safety device that opens the circuit when the motor overheats. GE's diagnostic guidance for this code is to check both motors for TCO continuity and replace the motor that has failed. Because the TCO is integrated into the motor housing, the entire motor assembly must be replaced.

Resetting the dishwasher by cutting power will temporarily clear the displayed code, but the underlying motor TCO failure will remain. Once the control board runs a cycle and checks the motor circuit again, F26 will return. A reset is useful for confirming the error is persistent, but it does not repair the failed TCO or the motor.

Repair costs vary depending on which motor has failed and local labor rates. A replacement circulation or drain motor for a GE dishwasher typically costs between $80 and $200 for the part alone. If you hire a technician, total repair costs including labor generally range from $150 to $350. Identifying the correct failed motor before ordering parts helps avoid purchasing an unnecessary component.

A knowledgeable DIYer can address F26 by using a multimeter to test continuity through each motor's TCO circuit and identifying which motor has failed. Replacing a dishwasher motor requires disconnecting power, accessing the sump area, and removing the pump assembly, which involves moderate mechanical skill. If you are not comfortable working around electrical components or disassembling the lower pump housing, a professional technician is recommended.

No, you should not continue operating the dishwasher while F26 is active. The error indicates a motor has reached an unsafe temperature and its safety cut out has tripped. Running the appliance in this condition risks further motor damage or overheating. The dishwasher should remain off until the faulty motor is identified and replaced.
