Haier Dishwasher won't start

If your Haier dishwasher won't start, the problem is usually a failed thermal fuse, a bad door switch, or a damaged wire harness, with a broken door latch, faulty main control board, or drain pump also able to stop the cycle. A blown thermal fuse cuts power when the dishwasher overheats, while a defective door switch or door latch can make the machine think the door is still open, so the dishwasher has power but will not start. If the start button seems to respond but nothing happens, check the wire harness for frayed or broken wires between the control board and pump components. The main control board can also cause a Haier dishwasher not starting, but it is often misdiagnosed, so test the simpler parts first. In some cases, a drain pump that cannot clear water before the fill cycle can keep the dishwasher from running. If your Haier dishwasher won't start or the dishwasher is not starting consistently, 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 dishwasher.

01 - Haier 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 - Haier 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 - Haier 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 - Haier 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 - Haier 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 - Haier 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.
