You rely on your Thermador dishwasher to keep your kitchen clean and well-maintained. If you start to hear odd noises from your dishwasher, however, it can be disconcerting. Sometimes strange noises can be fixed easily, but they can also be a sign of a more serious problem. Use this simple troubleshooting list to track down the source of the noise and make necessary repairs.


Clear the Chopper Blade

Under the lower spray arm and the dishwasher sump lies the chopper blade, one of the dishwasher parts that may cause unusual noises. If a solid piece of debris, such as a popcorn kernel, gets lodged in the chopper blade, it can produce a loud grinding noise. Turn off the dishwasher and clear the chopper blade to see if it resolves the problem. If not, it may need replacing.


Check the Water Inlet Valve

Your dishwasher's water inlet valve controls the flow of water into the dishwasher. If it doesn't open completely, it doesn't release enough water into the appliance. As a result, the pump may make a lot of noise as it tries to work without enough water to pump. Check the water inlet valve to see if it's opening and closing correctly, and replace it if necessary.


Replace the Dishwasher Pump Motor

You're likely to experience more than just problems with noise if your dishwasher's pump motor is defective. This dishwasher repair problem also results in decreased spray pressure, leading to dish loads that aren't fully cleaned. If you need to replace the pump motor, consider changing the dishwasher's seals at the same time.
