Gaggenau Dishwasher won't start

If your Gaggenau dishwasher won't start, start with the parts most likely to cut power or stop the cycle before it begins. A blown thermal fuse is the most common cause, since it shuts power off if the dishwasher overheats. Next, check the door switch, because the unit will not run if it thinks the door is open, even when it is shut. After that, inspect the wire harness for frayed or broken wires, especially if the start button seems to work but the dishwasher is not starting. A broken door latch can also keep the door switch from closing properly, and a failed main control board may not send voltage where it needs to go, though boards are often misdiagnosed. On some models, a bad drain pump can also prevent startup because the dishwasher drains water before the fill cycle begins. If your Gaggenau dishwasher has power but will not start, enter your model number on RepairClinic.com to find the exact thermal fuse, door switch, wire harness, door latch, main control board, or drain pump that fits your machine.

01 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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.
