People love Thermador dishwashers for their superior cleaning performance, quiet operation, and innovative features. These dishwashers are designed with advanced cleaning systems to remove food and stains, so you don’t have to scrub your dishes by hand. Although Thermador is one of the best luxury appliance companies, most appliances will experience at least one issue at some point.
Dealing with a finicky dishwasher is frustrating. Do you need help with Thermador dishwasher troubleshooting? We put together this Thermador dishwasher repair guide to help you identify common issues.
Common Thermador Dishwasher Issues & Fixes
Problem #1. Dishwasher Not Draining
Do you notice leftover water accumulating at the bottom of your dishwasher? A clogged drain, a broken or blocked hose, or a malfunctioning pump usually cause this.
How to Fix It:
Start by checking the drain for stuck food or blockages. If the drain hose is kinked or clogged, straighten or clean it out. If the issue persists, call a professional Thermador dishwasher technician. You may be dealing with deeper electrical or mechanical problems beyond basic troubleshooting.
Problem #2: Dishwasher Not Cleaning Properly
Are your dishes coming out dirty after a wash cycle? If dishes come out dirty, the detergent, water temperature, or blocked spray arms could be the issue.
How to Fix It:
The most simple fix could be changing your dishwasher detergent or water temperature. Check that the detergent dispenses correctly and the water temperature is at least 120°F. If these don’t work, a professional can diagnose and fix more serious issues like a malfunctioning pump, clogged spray arms, or a faulty water inlet valve.
Problem #3: Problem: Dishwasher is Noisy
Thermador dishwasher noise isn’t normal. These luxury dishwashers are designed to be quiet. If you hear unusual sounds like grinding, rattling, or high-pitched squealing, it’s a sign something may be wrong.
How to Fix It:
Start by finding out the cause of the weird noises. If it is an issue with the motor, a technician may need to replace it. Other parts, like the pump, spray arm, or door latch, can sometimes be repaired or adjusted.
Problem #4: Dishwasher Water Leaks
Do you ever see pools of water on your kitchen floor next to your dishwasher? Leaky dishwashers can cause water to pool around the appliance, leading to potential damage to your floors or cabinets. Water around your dishwasher can indicate a leaking door gasket, a damaged hose, or a faulty pump.
How to Fix It:
Call a technician to check for visible gasket cracks and ensure the hoses are correctly connected. If the leak persists, you may have a more severe issue, like a malfunctioning water inlet valve, a damaged drain pump, or internal seals that need replacement.
Problem #5: Dishwasher Won’t Start
What should you do if your Thermador dishwasher won’t turn on? It’s frustrating when your dishwasher refuses to start, leaving you with a sink full of filthy dishes.
How to Fix It:
Start simple. Check that your appliance is plugged in and your circuit breaker hasn’t tripped. Is the door securely closed, and is the latch functioning? A damaged latch can stop the door from closing. Next, check the control panel to make sure your buttons aren’t stuck. If these basic checks don’t resolve the issue, the problem might be a blown thermal fuse or a faulty motor start relay, requiring testing and potential replacement. For persistent concerns, contact a certified Thermador technician.
