Ikea Dishwasher won't start

If your Ikea dishwasher won't start, the most common causes are a blown thermal fuse, a failed door switch, or a damaged wire harness that is not sending power where it needs to go. A bad door latch is another likely problem, since the dishwasher will not run if the door is not fully latched and the switch does not close. After that, check the main control board, but save it for later because control boards are often misdiagnosed. In some cases, an Ikea dishwasher not starting can also be tied to a drain pump problem, since the unit may need to drain before the fill cycle begins. If your dishwasher has power but will not start, or the start button seems to work but nothing happens, these are the parts to inspect first. Testing a thermal fuse or door switch with a multimeter can quickly narrow it down. Once you know the issue, enter your model number on RepairClinic.com to find the exact Ikea dishwasher replacement part, whether you need a thermal fuse, door switch, wire harness, door latch, main control board, or drain pump.

01 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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.
