Dishwasher woes: why doesn’t my thermador start? the ultimate troubleshooting guide

Are you experiencing a frustrating situation where your Thermador dishwasher refuses to start, leaving you with a pile of dirty dishes? Don’t worry; you’re not alone. Many homeowners encounter this issue, and it can be a source of great annoyance. To help you resolve this problem effectively, we’ve compiled a comprehensive guide that explores the various reasons why your Thermador dishwasher might not start.

Electrical Issues

1. Power Supply Failure:

• Ensure that the dishwasher is plugged into a working electrical outlet.
• Check the circuit breaker or fuse box to verify if the dishwasher’s circuit has tripped or blown.
• Reset the circuit breaker or replace the blown fuse if necessary.

2. Faulty Door Switch:

• The door switch prevents the dishwasher from operating when the door is open.
• Inspect the door switch for any damage or misalignment.
• Replace the door switch if it’s faulty.

Water Supply Problems

3. Water Supply Valve Closed:

• Check if the water supply valve under the sink is fully open.
• If the valve is closed, open it completely to allow water flow to the dishwasher.

4. Clogged Water Inlet Hose:

• Over time, sediment and debris can accumulate in the water inlet hose, restricting water flow.
• Disconnect the water inlet hose and check for any clogs.
• Clean the hose thoroughly or replace it if necessary.

5. Faulty Water Inlet Valve:

• The water inlet valve controls the water flow into the dishwasher.
• Listen for a clicking sound when the dishwasher is turned on. If you don’t hear a click, the water inlet valve may be faulty.
• Replace the water inlet valve if it’s not functioning properly.

Mechanical Issues

6. Faulty Door Latch:

• The door latch keeps the dishwasher door securely closed during operation.
• Inspect the door latch for any damage or misalignment.
• Replace the door latch if it’s faulty.

7. Broken Drive Motor:

• The drive motor powers the dishwasher’s wash and rinse cycles.
• If the drive motor is broken, the dishwasher will not start.
• Replace the drive motor if it’s faulty.

8. Faulty Control Board:

• The control board is the brain of the dishwasher, controlling all its functions.
• If the control board is faulty, the dishwasher may not start or function correctly.
• Contact a qualified appliance repair technician to diagnose and replace the control board if necessary.

Other Possible Causes

9. Child Lock Activated:

• Check if the child lock feature is activated on the dishwasher’s control panel.
• Deactivate the child lock to allow the dishwasher to start.

10. Overloaded Dishwasher:

• Overloading the dishwasher can prevent it from starting or washing dishes effectively.
• Remove excess dishes and ensure they are properly spaced within the dishwasher.

11. Software Glitch:

• In rare cases, a software glitch can cause the dishwasher to malfunction.
• Reset the dishwasher by unplugging it for 30 seconds and then plugging it back in.
