Hotpoint Dishwasher won't start

If your Hotpoint dishwasher won't start, start with the parts most likely to cut power or keep the machine from recognizing that it is safe to run. The most common cause is a blown thermal fuse, which shuts the dishwasher down if it overheats. Next, check the door switch, since a failed switch can make the dishwasher act like the door is still open. If the start button seems to work but the dishwasher not starting problem continues, inspect the wire harness for broken or frayed wires that can stop power from reaching key components. After that, look at the door latch, because if the door does not close and latch fully, the switch will not allow a cycle to begin. The main control board can also cause a Hotpoint dishwasher has power but will not start issue, but it is less common and should be ruled in only after the fuse, switch, harness, and latch have been checked. On some models, a failed drain pump can also prevent startup if the unit cannot drain before filling. Enter your model number on RepairClinic.com to find the exact Hotpoint thermal fuse, door switch, wire harness, door latch, main control board, or drain pump for your dishwasher.

01 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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.
