Common Error Codes
Miele dishwashers use error codes to show specific problems. These codes help identify what needs fixing. Knowing common error codes saves time and effort. It makes troubleshooting easier and faster. Below are frequent error codes grouped by their issues. Understanding these can help you keep your dishwasher working well.
Water Supply Issues
Water supply errors happen when water cannot enter the dishwasher. The machine may show codes like E10 or E20. These mean the water inlet valve is blocked or the hose is kinked. Check if the tap is fully open. Clean the water filter to allow good flow. Low water pressure can also cause these errors.
Drainage Problems
Drainage errors occur when water cannot leave the dishwasher. Codes like E90 or E91 point to this issue. The drain hose may be clogged or bent. The filter could be dirty and blocking water flow. Pump failure is another cause. Clear any blockages and inspect the drain system carefully.
Heating And Drying Faults
Heating errors show if the dishwasher cannot heat water or dry dishes. Codes such as E30 or E40 are common. The heating element might be faulty or broken. A malfunctioning thermostat can stop proper heating. Fans or sensors that aid drying can also fail. These faults cause dishes to stay wet after a cycle.
Sensor And Electrical Errors
Sensors monitor the dishwasher’s performance. Electrical errors happen when sensors or control boards fail. Codes like E50 or E60 often appear. Wiring issues or loose connections can cause these errors. Faulty sensors may give wrong readings. Inspect the wiring and reset the machine if needed.

Resetting The Dishwasher

Checking Water Inlet And Filters
Ensure the water faucet is fully open. Look for kinks in the water inlet hose. Remove and clean the inlet filter gently. Dirt or debris can block water flow. Low water pressure causes errors too. Fix these issues for smooth operation.
Inspecting Hoses And Spray Arms
Check drain and inlet hoses for bends or clogs. Clear any blockages found inside. Remove spray arms and clean holes with a brush. This allows water to spray properly. Proper water circulation prevents error messages and poor cleaning.

Quick Fixes For Common Errors
Miele dishwashers are reliable, but errors can happen. Quick fixes solve many common problems fast. These simple steps help you avoid service calls and get your dishwasher working again. Understanding these fixes saves time and money.
Clearing Blocked Filters
Blocked filters stop water flow and cause error codes. Remove the bottom rack to access the filter. Take out the filter and rinse it under running water. Use a soft brush to clear debris. Put the filter back securely before running the dishwasher again. This often fixes drainage and cleaning issues.
Unkinking And Replacing Hoses
Kinked hoses block water supply or drainage, triggering errors. Pull out the dishwasher carefully to check hoses behind it. Straighten any bends or twists in the hose. If the hose is cracked or damaged, replace it with a new one. Secure the hose tightly to prevent leaks. Proper hose flow ensures smooth dishwasher operation.
Addressing Heating Element Issues
The heating element warms water for effective cleaning and drying. Faulty elements cause error codes and wet dishes. Check if the dishwasher heats up during a cycle. If not, the element may need testing with a multimeter. Replace the heating element if it shows no continuity. This fix improves drying and wash performance quickly.
When To Contact A Professional
Knowing when to contact a professional for your Miele dishwasher saves time and prevents damage. Some issues need expert care beyond basic troubleshooting. Understanding the signs helps you decide quickly.
Persistent Error Codes
Error codes that keep showing after resets signal deeper problems. These codes often point to system faults not fixed by simple steps. Continuous errors require a technician’s diagnosis to avoid further damage.
Faulty Components Replacement
Some parts in your dishwasher wear out or break over time. Replacing these parts needs special tools and skills. Professionals ensure the right components are used and installed correctly, keeping your dishwasher safe and efficient.
Authorized Service Options
Using authorized Miele service centers guarantees genuine parts and trained technicians. They follow manufacturer standards and provide reliable repairs. This also protects your warranty and extends the dishwasher’s lifespan.

Regular Maintenance Routines
Clean the filter after every few cycles. Remove food particles to prevent clogs. Check spray arms for blockages or damage. Wipe door seals gently to avoid mold. Run a cleaning cycle with dishwasher cleaner monthly. Inspect hoses for leaks or cracks regularly. Replace worn parts promptly to keep performance high.
Proper Loading Techniques
Place dishes so water reaches all surfaces. Avoid overcrowding to allow free water flow. Position large items at the sides or back. Face pots and pans downward for better cleaning. Use the correct racks for cutlery and glasses. Keep items from blocking the detergent dispenser. Follow the user manual for best loading advice.
Water Quality Considerations
Use soft water to prevent mineral buildup. Install a water softener if water is hard. Check water temperature; ideal is 120°F (49°C). Avoid using too much detergent; it causes residue.
