Frigidaire Dishwasher won't start

If your Frigidaire dishwasher won't start, the problem is usually tied to a failed thermal fuse, a bad door switch, or a damaged wire harness. A blown thermal fuse cuts power to the dishwasher completely, so checking it for continuity is a smart first step. Next, inspect the door switch, since the dishwasher not starting can be as simple as the machine not sensing that the door is closed. After that, look over the wire harness for frayed or broken wires that may keep power from reaching key components. Less often, a broken door latch can stop the cycle from beginning, a main control board may fail to send voltage where it needs to go, or a drain pump that cannot clear water before the fill cycle may keep the unit from running. If your Frigidaire dishwasher has power but will not start, entering your model number on RepairClinic.com is the fastest way to find the exact replacement thermal fuse, door switch, wire harness, door latch, main control board, or drain pump for your specific dishwasher.

01 - Frigidaire Dishwasher Thermal Fuse

The thermal fuse shuts off power to the dishwasher if it overheats. If the thermal fuse blows, it will prevent the dishwasher from starting. To determine if the thermal fuse is defective, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it.

02 - Frigidaire Dishwasher Door Switch

The door switch prevents the dishwasher from running while the door is open. If the door switch is defective, the switch will prevent the dishwasher from running even when the door is closed. To determine if the door switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.

03 - Frigidaire Dishwasher Wire Harness

If the dishwasher start button appears to work, but the dishwasher still won't start, a wire harness which sends power from the control board to the pump components could be damaged. Inspect the wire harness for any frayed or broken wires and replace if necessary.

04 - Frigidaire Dishwasher Door Latch

The door latch ensures that the dishwasher door latches shut. If the door does not latch properly, the door switch might prevent the dishwasher from running. If the door latch is broken, replace it.

05 - Frigidaire Dishwasher Main Control Board

The main control board provides power to nearly every component of the dishwasher. If there is a problem with the main control board, it might not send voltage to the dishwasher, causing the dishwasher not to start. Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the main control board.

06 - Frigidaire Dishwasher Drain Pump

A dishwasher drain pump assists in removing the water from the tank at various times during operation. Since the unit will drain some water from the tank prior to the fill cycle beginning, a faulty drain pump unable to drain any water could prevent the dishwasher from starting.
