GE Dishwasher Error Code F62

F62 means the control board has detected that the dry heater fan is not operating at or above 2,500 RPM. This fan circulates hot air during the drying cycle. The fault can be caused by a loose wiring harness, a blocked fan blade, or a failed fan motor.

The dishwasher may still run a wash cycle, but the drying phase will not function correctly with a failed dry heater fan, meaning dishes will come out wet. Running the machine repeatedly in this condition can also stress other components. It is best to resolve the F62 fault before continuing regular use.

A reset may clear the code temporarily, but F62 will return if the underlying fan fault is not corrected. The control board will detect the fan speed problem again on the next drying cycle. Address the fan harness connection or fan motor before relying on a reset.

Start by checking that the dry heater fan wiring harness is fully plugged in, since a loose connection is the simplest cause. Next, inspect the fan blade for obstructions and clear any debris. If the harness is connected and the fan blade spins freely but the error persists, test the fan motor to verify it reaches 2,500 RPM under power. A motor that cannot meet this threshold needs to be replaced.

If the fix is a reseated wiring harness or clearing a fan obstruction, there is no parts cost and you can do it yourself in under 30 minutes. If the dry heater fan motor needs replacement, the part typically costs between $30 and $80 depending on the specific GE model. Professional labor to diagnose and replace the fan motor generally adds $100 to $200, making total repair cost in the $130 to $280 range when using a technician.
