Let’s take a look at the more common reasons why your dishwasher won’t start and remember with all these checks make sure there is no power to your dishwasher before you start searching.

Dishwasher Won’t Start

Problems With The Door

Your dishwasher’s door can be the cause of many problems and if you find yourself facing a dishwasher that won’t start then you should check out the door first. If there’s a problem with the latch or switch that’s stopping the door closing, then your dishwasher won’t start.

Inspect the door closely to see if anything has come loose, if you want to examine the door latch more closely you’ll need to unscrew the inner door panel. Be careful if you decide to do this because it can be easy to cause more damage accidentally. If you really want to be 100% safe call in a professional dishwasher repair technician to check it for you.

The Drive Motor

The drive motor might sound extreme but it’s just the name given to the motor that circulates water inside the dishwasher. A defective drive motor is a more common problem than many people think and is usually simple to replace.

If you have a multi-meter you can test the drive motor yourself but a more obverse sign that the motor is the problem with your dishwasher is the presence of a loud, humming noise that comes through the machine when you try to power on.

The Timer/ Control Panel

There are many different models of dishwasher available and one of the biggest differences you’ll see between newer and older models is the timer it could be a manual one or a more advanced automatic electronic control panel.

These do more than just tell you the time left in a cycle they are responsible for powering the motor in the drain pump. Listen carefully if you don’t hear the pump then it’s possible there could be an issue with the timer or control panel.

If you notice the timer is taking longer or finishing early, then that’s also a sign of a potential problem. More advanced models of dishwasher will also usually display an error code that you can check in your instructions manual as well. Problems with the timer/ control panel are usually very complex so repairs and tests should only be carried out by professional dishwasher repair engineer.

The Fuse and Thermal Fuse

A dishwasher is no different than any other electronic appliance by meaning it as fuse in its plug. So, if you suddenly find yourself with a dishwasher that won’t power on then replace the fuse and see what happens. It’s a common solution that can surprisingly fix a lot of problems so make sure you try replacing the fuse.

The thermal fuse, however, is a little more complicated, this fuse can be found in some more modern dishwasher models. The thermal fuse is on the control board of the machine and can be checked using a multi-meter however it’s highly recommended that you call in a professional to handle this for you.

The Selector Switch

It might seem strange but the fact that a switch hasn’t been fully depressed can cause a lot of problems with a dishwasher. The selector switch is what you use to scroll through different washing cycles, but it’s also used in the dishwasher’s fill circuit as well.

A lot of issues can cause the selector switch to not work including the fact that it’s not properly depressed. If you’re lucky simply pushing the switch again might be enough to fix this problem but it will likely need to be disassembled or possibly replaced altogether.

If there’s an internal issue with the selector switch, then you’ll need to call in a dishwasher repair engineer to test it and then fix the issue. While they can be tested using a multi-meter, other repairs are more complex and should only be done by an experienced professional.
