In this case, resetting your machine might do the trick.

What Issues Would Prevent My Thermador Dishwasher to Reset?

If you are having trouble resetting your Thermador dishwasher, there may be a few issues that are causing the problem.

Here are some common issues that could be preventing your dishwasher from resetting:

Hard Water Buildup

Over time, hard water can cause limescale to build up in your dishwasher's spray arms, filters, and other components.

Limescale is a type of mineral deposit left behind on dishes and the dishwasher inside after the water has evaporated.

The buildup can cause your dishwasher to malfunction and prevent it from resetting, making it less effective at cleaning your dishes.

To prevent limescale buildup, you can use a water softener or add a rinse aid to your dishwasher.

Using Too Much Detergent

When you use too much detergent, it can create excessive suds that can damage your dishwasher's pump and other components.

Adding detergent to dishwasher

To prevent this issue, make sure to follow the detergent manufacturer's instructions and use the correct amount of detergent.

Problems in The Drain Pump

The drain pump is a crucial component of your dishwasher, responsible for expelling dirty water from the tub via the drain hose and kitchen drain line.

If your dishwasher is not draining properly, it may be due to a problem with the drain pump.

A clogged or damaged drain pump can prevent your dishwasher from resetting and cause issues with cleaning effectiveness and odors.

If you've tried resetting your dishwasher and the same drain pump-related error code keeps appearing, it may be time to clean or replace the drain pump.


Leaking can also be a reason why your dishwasher isn't resetting.

A leaking dishwasher can damage the electrical components and cause it to malfunction.

To fix this issue, locate the source of the leak and replace or repair the damaged parts.

Other Troubleshooting Tips on Thermador Dishwasher

If resetting your Thermador dishwasher doesn't solve your problem, don't worry. There are a few other troubleshooting tips that you can try. Here are some things to check:

Check the Water Supply

Ensure your dishwasher has enough water supply and the water intake valve is not clogged.

If you have hard water, try cleaning the spray arms and the dishwasher interior with a mixture of vinegar and water.

Doing so will help remove any mineral buildup that could be affecting your dishwasher's performance.

Check the Drain Hose

See if the drain hose is blocked or kinked. If it is, straighten it out or clean it to improve water flow.

Check the Dishwasher Filter

A dirty filter can cause your dishwasher to work improperly. Detach the filter and use warm, soapy water to clean it.

You can find the filter around the base of the spray arm or under the bottom rack.

Check the Detergent Dispenser

If your dishwasher isn't dispensing detergent properly, ensure that the dispenser is clean and free of blockages.

You can also try switching to a different detergent type to see if that solves the problem.
