Common Issues
Thermador dishwashers are known for their high performance and sleek design. However, like any appliance, they are not immune to issues. Understanding the common problems can help you troubleshoot effectively and maintain your dishwasher’s efficiency. Let’s dive into some of the frequent concerns Thermador dishwasher owners face.
Water Leaks
Water leaks can be a real headache. Imagine walking into your kitchen and finding a puddle on the floor. This issue usually stems from a few potential sources:
- Door Seal: Over time, the door seal can wear out, allowing water to escape. Inspect the seal for cracks or gaps.
- Hoses: Check the hoses connected to your dishwasher. If they are loose or damaged, they might be the culprit.
- Water Inlet Valve: A faulty valve can cause leaks. If you notice water pooling even when the dishwasher is off, the valve might need replacement.
Regular maintenance and timely repairs can prevent these issues from becoming a bigger problem. A little care goes a long way!
Not Cleaning Dishes
There’s nothing more frustrating than opening your dishwasher to find your dishes still dirty. This can happen for several reasons:
- Clogged Spray Arms: Food particles can clog the spray arms, reducing water pressure and cleaning efficiency. Clean the spray arms regularly to avoid this issue.
- Detergent Issues: Using the wrong detergent or too much of it can lead to residue on your dishes. Make sure you’re using the recommended detergent and the right amount.
- Filter Problems: A clogged filter can prevent the dishwasher from cleaning properly. Clean the filter according to the manufacturer’s instructions.
By keeping these common issues in mind and addressing them promptly, you can ensure your Thermador dishwasher continues to perform at its best. After all, a well-functioning dishwasher means one less thing to worry about in your busy life.
Remember, while some problems can be fixed with a bit of DIY, don’t hesitate to call a professional if you’re unsure. Better safe than sorry, right?

Error Codes
Thermador dishwashers are known for their reliability and efficiency. However, like any other appliance, they can sometimes encounter issues. One common way these problems manifest is through error codes. Understanding these codes can help you diagnose and fix issues quickly, saving you from unnecessary headaches. Let’s delve into the world of Thermador dishwasher error codes and how to interpret and resolve them.
Interpreting Codes
When your Thermador dishwasher displays an error code, it’s like a cry for help. Each code corresponds to a specific problem. Here’s a quick guide to deciphering these codes:
- E01 to E30: These codes generally indicate a problem with the water supply or drainage. It could be anything from a blocked filter to a faulty water inlet valve.
- E31 to E50: These codes often point to electrical issues. You might be dealing with a malfunctioning circuit board or a broken wire.
- E51 to E70: These are usually related to temperature problems. The heating element or thermostat might be to blame.
Understanding these codes can help you pinpoint the issue and decide whether it’s a DIY fix or if you need professional help.
Common Fixes
Once you’ve identified the error code, the next step is to fix the problem. Here are some common fixes for frequent error codes:
Error Code | Possible Cause | Solution |
---|---|---|
E24 | Drainage Issue | Check the drain hose for clogs. Clean the filter and ensure the pump is functioning properly. |
E15 | Water Leakage | Inspect the dishwasher for leaks. Look at the door gasket and the water inlet valve. |
E09 | Heating Element Fault | Test the heating element for continuity. Replace if necessary. |
Sometimes, a simple reset can solve the problem. Unplug the dishwasher for a few minutes, then plug it back in and see if the error persists. This can sometimes clear minor software glitches.
Dealing with error codes can be frustrating, but with the right knowledge, you can often resolve the issue yourself. Remember, if in doubt, it’s always best to consult the manual or reach out to a professional.

Noise Problems
Thermador dishwashers are known for their high performance and sleek design. However, like any other appliance, they can sometimes run into issues. One common problem that many Thermador dishwasher owners experience is noise. If your dishwasher is making strange sounds, it could be a sign that something is wrong. In this section, we’ll explore the different noises your Thermador dishwasher might make, what they mean, and how you can fix them.
Identifying Noises
Let’s start by identifying the types of noises you might hear from your Thermador dishwasher. Each noise can indicate a different problem. Here are some common noises and what they might mean:
- Grinding: This could mean that there is something caught in the dishwasher’s motor or pump.
- Humming: A humming noise is often caused by a problem with the motor or a clogged filter.
- Banging: If you hear a banging noise, it could be due to loose dishes or a problem with the water inlet valve.
- Rattling: Rattling usually indicates that something is loose inside the dishwasher, such as a utensil or a part of the dishwasher itself.
Solutions
Once you’ve identified the noise, the next step is to find a solution. Here are some tips for fixing common noise problems:
- Grinding Noise: First, check the bottom of the dishwasher for any debris that might be caught in the motor or pump. Remove any debris you find. If the noise persists, it might be time to call a professional.
- Humming Noise: Check the filter and clean it if necessary. If the filter is clean and the noise continues, there might be an issue with the motor, which would require professional help.
- Banging Noise: Ensure that all dishes are properly secured and not banging against each other or the dishwasher walls. If the noise is coming from the water inlet valve, you may need to replace it.
- Rattling Noise: Check inside the dishwasher for any loose items. Make sure that all utensils are securely placed in the utensil rack. If a part of the dishwasher is loose, you might need to tighten it or call a technician.
By identifying and addressing these noises, you can keep your Thermador dishwasher running smoothly and quietly. Remember, regular maintenance can prevent many of these issues from occurring in the first place. If you’re ever in doubt, don’t hesitate to contact a professional for assistance.

Door Seal Problems
Thermador dishwashers are known for their quality and reliability. Yet, even the best appliances can face issues. One common problem with Thermador dishwashers is door seal problems. A faulty door seal can lead to leaks and poor cleaning performance. Addressing this issue promptly can save you from further damage. This section will guide you on how to inspect and replace the door seal.
Seal Inspection
Inspecting the door seal is the first step. Open the dishwasher door and locate the rubber seal around the perimeter. Look for any signs of wear or damage. Cracks, tears, or deformations indicate a problem. Run your fingers along the seal to feel for irregularities. Check for any debris or buildup that might affect the seal. A thorough inspection can help you identify the issue.
Replacement Steps
Replacing the door seal is straightforward. First, disconnect the dishwasher from the power supply. Open the door and remove the old seal by pulling it out gently. Clean the groove where the old seal was placed. Remove any debris or residue. Take the new seal and align it with the groove. Press it firmly into place, ensuring it fits snugly. Close the door and check for any gaps. Reconnect the power supply and run a test cycle. Make sure there are no leaks.
Drainage Issues
Is your Thermador dishwasher giving you a headache with drainage issues? You are not alone. Many Thermador users face similar challenges. A dishwasher that doesn’t drain properly can be very frustrating. Imagine opening your dishwasher to find it full of dirty water! Let’s dive into the common drainage problems and how to fix them.
Clogged Drains
One of the most common issues is clogged drains. Food particles, grease, and soap scum can build up in the drain hose, causing a blockage.
- First, you need to check the drain filter. It’s usually at the bottom of the dishwasher.
- Remove any food debris or gunk you find. A good rinse under warm water can help.
- If that doesn’t solve the problem, check the drain hose. It might be kinked or clogged.
Pro tip: Use a pipe cleaner or a wire hanger to clear any blockages in the hose. But be gentle to avoid damage!
Pump Malfunctions
Another culprit could be pump malfunctions. The pump is essential for pushing the water out of the dishwasher. When it fails, water stays put.
- First, listen to your dishwasher. If you don’t hear the pump running, it might be broken.
- Check for visible signs of damage or wear and tear.
- If you’re comfortable with DIY fixes, you can remove the pump and inspect it. Sometimes, cleaning it out can work wonders.
If all else fails, it might be time to call in a professional. Replacing a pump is tricky and might need expert hands.
Dealing with drainage issues in your Thermador dishwasher can be a hassle, but with a little know-how, you can often fix the problem yourself. Whether it’s a clogged drain or a pump malfunction, understanding these common issues can save you time and money. Remember, regular maintenance is key. Keep your dishwasher clean and check it periodically to avoid future problems.

Control Panel Malfunctions
When it comes to Thermador dishwashers, the control panel is the brain of the operation. If it stops working, you’re left with a fancy appliance that just sits there. This can be frustrating, especially after a long day when all you want is clean dishes. Below, we dive into common issues and solutions related to control panel malfunctions.
Unresponsive Buttons
Have you ever pressed a button on your Thermador dishwasher and nothing happened? You’re not alone. This is a common problem that can stem from several issues.
- Dirty Buttons: Over time, grime can build up on the control panel, causing the buttons to become unresponsive. A simple cleaning might do the trick.
- Moisture: Water and electronics don’t mix well. If moisture gets behind the control panel, it can cause the buttons to malfunction.
- Wear and Tear: Like any other appliance, wear and tear can cause buttons to stop working. If your dishwasher is getting old, this might be the cause.
Resetting The Panel
Sometimes, all you need is a quick reset to get your dishwasher back in action. Think of it like rebooting your computer when it freezes.
- Turn off the dishwasher by pressing the power button.
- Unplug the dishwasher from the electrical outlet. If you can’t reach the plug, turn off the circuit breaker.
- Wait for a few minutes. This allows the system to fully reset.
- Plug the dishwasher back in or turn on the circuit breaker.
- Turn on the dishwasher and test the control panel.
If the reset doesn’t work, it might be time to call in a professional. But before you do that, make sure to check the user manual. Sometimes, the solution is simpler than you think.
So there you have it! Whether it’s unresponsive buttons or the need for a reset, these tips should help you troubleshoot your Thermador dishwasher. Remember, a little DIY can go a long way, but don’t hesitate to seek professional help if needed. Happy dishwashing!
Water Temperature Problems

Inadequate Heating
Inadequate heating is a common problem. The dishwasher may not heat the water enough. This can leave dishes dirty. The heating element may be faulty. It needs to be checked and possibly replaced. Regular maintenance can help avoid this issue.

- Run a Cleaning Cycle: Once a month, run an empty cycle with a dishwasher cleaner or a cup of vinegar. This removes buildup and keeps the interior fresh.
Periodic Inspections
Regular inspections can help you spot potential issues before they become major problems. Here are some areas to check:
- Spray Arms: Ensure the spray arms rotate freely and are not clogged with food particles. Clean any blocked holes with a toothpick.
