How To Fix A Dishwasher That Won’t Start?

It can be painful to try to use your dishwasher, but it just doesn’t start. This can frustrate you, especially when you consider the time and money that you will spend to get it fixed. The good news is that there are so many fixes that you can personally implement to quickly get it back up and running. The information below will enable you to diagnose and fix faulty parts.

Power supply

If your dishwasher is not getting power, there may be a problem with the electrical contacts. Ensure that the socket is properly plugged in. You can test the socket by plugging out the dishwasher and plugging in another device. This seems simple, but it just may do the trick.

Door switches

This is also referred to as the door interlock switch or the door lock switch. It is found inside the door panel. This switch is a safety feature that stops the dishwasher from running when the door is open. If it is faulty, your dishwasher will not start. To check it out, remove the control panel and test it for continuity.


The timer or electric control supplies power to the water inlet valve, pump motor, drain pump motor and the heater circuit. It ensures that this is done in a specific sequence. It has a number of electrical contacts driven by a tiny motor. All this is enclosed in a timer housing. You can use a multi-meter to check the contacts for continuity. Turn off the power supply before trying this out. To access the timer, you will have to remove the inner door panel. If you find it problematic, you can replace it.

Selector switches

You will find this at the control panel and will need to detach the inner door panel in order to access it. The work of the selector switch is to determine different selections for individual cycles; for example the heated wash and heated dry wash cycles. If it is defective or its buttons are not fully depressed, the dishwasher will not start. You can check it for continuity using a multi-meter to determine whether it has a problem and replace it if necessary.

Thermal fuse

The thermal fuse is designed in such a way that if the dishwasher overheats, it blows. A dishwasher won’t start if the thermal fuse is blown. You will need to replace it so that the dishwasher works. In most models, this fuse is found in the area where the control panel is. To check if it is faulty, remove the control panel to access the thermal fuse then test it for continuity.

Other parts to consider checking include the motor start relay and drive motor. It doesn’t take much time to do all the checks mentioned here. Just imagine the joy of being able to fix your dishwasher without having to call a professional appliance repair company. Try the methods above and you may be shocked to see your imagination come true. However, if you have tried them all and still the dishwasher won’t start, do not hesitate to contact a professional dishwasher repair service technician.
