Here we will discuss some common issues and solutions for Thermador dishwasher won’t start.

Defective Thermal Fuse

The thermal fuse prevents dishwashers from overheating. If the thermal fuse blows, the dishwasher will not turn on.

Test the thermal fuse for continuity using a multimeter to make sure it has power running through it by touch.

If it does not, replace the fuse with a new one of the same kind of a different type rated for higher amperage if you suspect that your original thermal fuse was faulty or blown out due to lowered resistance levels.

Touchpad Faults

To figure out if your touchpad is having problems, try pressing the buttons on it a few times. If some of the buttons don’t respond, there might be something wrong with your touchpad.

First, find out if the touchpad is sold separately from the control panel or if you have to purchase it alongside the rest of that component.

If it can be bought separately and you need to replace it. If not, and if all else fails, proceed with replacing both components altogether.

Faulty Door Switch

The door switch prevents the dishwasher from running while the dishwasher door is open. Even when the dishwasher door is closed, a defective door switch will prevent the dishwasher from operating.

A multimeter can be used to test whether there is continuity between both wires of the switch; if there is none, then the switch needs to be replaced.

Defective Door Latch

The latch on the dishwasher door is what keeps the door shut so that the machine can perform its functions.

In order to allow for water to circulate around the inner workings properly, you must ensure that your dishwasher is dry before replacing a latch.

Timer Failure

The timer on a dishwasher is like the dial-in timing device. If your watch has a broken timing dial, the hands won’t be able to grip it correctly and everything will stop working. You might not realize how serious the problem is.

The timing of the dishwasher may have been cut off from the power source and now might not send any electricity or water flow anywhere.

Check out all the other connections that connect with timers for backup wiring; these keep things running if anything happens to the dial first.

Faulty Main Control Board

There are many electronic parts within a dishwasher that make it run, but the main control board has primary responsibility for making sure the machine can do its job.

If there’s a problem with this critical piece, it might cut off power to the rest of the appliance, causing the dishwasher to stop running.

The main control board is often misdiagnosed, with service technicians thinking they need to replace this pricey part when in reality they could fix the problem with something less expensive and complex.


There’s a reset button on the dishwasher, right?

If your dishes are not coming out clean or you see residue on them after they’ve run, you might need to reset your dishwasher.

Press the Start/Reset button on the appliance and wait a few minutes to accomplish this most commonly.

If your dishwasher still doesn’t start up, please check if there’s some water left in it before proceeding with the next step.

Make sure the appliance is completely dry before powering it off at the fuse box or circuit breaker.

The system will then need to be rebooted. Last but not least, please unplug it if leaving for several days so that no one accidentally turns it on.
