Your thermador dishwasher won’t start? here’s the shocking truth!

If your Thermador dishwasher has suddenly gone on strike, leaving you with a pile of dirty dishes and a sense of frustration, you’re not alone. This common issue can be caused by a variety of factors, both simple and complex. In this comprehensive guide, we’ll delve into the possible reasons behind your dishwasher’s reluctance to start and provide step-by-step troubleshooting solutions.

Common Causes and Troubleshooting Tips

1. Power Supply Issues

• Check the power cord: Ensure the power cord is securely plugged into a working outlet. Inspect the cord for any damage or kinks.
• Reset the circuit breaker or fuse: A tripped circuit breaker or blown fuse can cut off power to the dishwasher. Reset the circuit breaker or replace the fuse as needed.

2. Door Switch Malfunction

• Check the door latch: The dishwasher door must be fully closed for the switch to activate. Open and close the door firmly to ensure proper latching.
• Test the door switch: Using a multimeter, test the continuity of the door switch. If the switch is faulty, it needs to be replaced.

3. Control Panel Issues

• Check the control panel: Inspect the control panel for any loose or damaged buttons. Clean the buttons with a damp cloth to remove any debris.
• Reset the dishwasher: Unplug the dishwasher for a few minutes and then plug it back in. This may reset the control panel and resolve any glitches.

4. Water Supply Problems

• Check the water supply: Ensure the water supply valve is open and there is sufficient water pressure. Run water from a nearby faucet to confirm.
• Clean the water inlet valve: Over time, sediment can accumulate in the water inlet valve, blocking water flow. Clean the valve by removing the filter screen and flushing it with water.

5. Drain Issues

• Check the drain hose: Inspect the drain hose for any kinks or blockages. Straighten out any kinks and remove any debris.
• Clean the drain pump: The drain pump can become clogged with food particles or other debris. Remove the drain pump filter and clean it thoroughly.

6. Mechanical Problems

• Check the motor: A faulty motor can prevent the dishwasher from starting. Listen for any unusual noises or vibrations when turning on the dishwasher.
• Inspect the drive belt: The drive belt connects the motor to the pump and spray arms. Check if the belt is loose or broken and replace it if necessary.

7. Electronic Control Board Issues

• Check the electronic control board: The electronic control board is the brain of the dishwasher, controlling all its functions. If the board is damaged or malfunctioning, it can prevent the dishwasher from starting.
• Contact a qualified technician: Electronic control board issues typically require professional repair. Contact an authorized Thermador technician for assistance.

Key Points: Restoring Your Dishwasher to Pristine Performance

By following these troubleshooting steps, you can identify and resolve the issue causing your Thermador dishwasher to not start. If the problem persists, it’s advisable to contact a qualified appliance repair technician for further diagnosis and repair. Remember, proper maintenance and regular cleaning can help prevent future dishwasher problems and ensure optimal performance.
