Frigidaire Dishwasher Circuit Board Failure

Dishwasher Will Not Start

• A Frigidaire dishwasher circuit board malfunction can prevent the dishwasher from starting. The circuit board’s thermal fuse may need replacing, and not the entire board, according to the appliance repair website Repair Clinic. Be sure to rule out other possible reasons why the dishwasher won’t start, which include making sure the door is firmly closed, checking for blown fuses or tripped circuit breakers, and checking the machine’s buttons to verify that the appliance is not set on delay.

Dishwasher Will Not Fill with Water

• A breakdown in the circuit board can also hinder the dishwasher’s ability to fill with water. The circuit board regulates the appliance’s ability to release water into the machine and a malfunction will impede this function. Also, check to be sure that the float isn’t trapped in the up position, and inspect the area to see if there is any silverware trapped underneath the float, which would prevent it from lowering to the correct position to initiate water flow.

Dishwasher Will Not Heat Water

• The dishwasher may not heat water if there is a circuit board failure. One of the board’s functions is to activate the heating element and the thermostat, but a malfunction can prevent triggering either one or the other. You should also make sure that the heating element is not covered with soap deposits, however, because this would also prevent proper functioning of the part.

Dishwasher Will Not Pump Water Out

• A circuit board failure can also obstruct the pump’s ability to force water out of the dishwasher. At the appropriate time, the board signals the pump to push water down the drain, but a faulty board will not alert the pump to start this function. You should also check to see if there is an obstruction in the pump, however, because this can also cause water to remain in the dishwasher.

Circuit Board Replacement

• If it has been determined that the dishwasher’s problems are the result of a circuit board failure, this part will have to be replaced because it is not repairable. Frigidaire makes several dishwasher circuit boards, so it’s important to make sure that you purchase the correct one for your appliance. As of the time of publication, replacement circuit boards range in price from $60 to $150, depending on the dishwasher’s model.
