Miele Dishwasher Error Codes: What They Mean and How to Respond

Decode your Miele dishwasher's error messages and learn when you can fix issues yourself vs. when to call for service.

Miele dishwashers are engineered with sophisticated diagnostics that alert you to problems through error codes. Understanding these codes helps you respond appropriately—sometimes resolving issues yourself, other times knowing professional service is needed.

How Miele Error Codes Display

• Depending on your model, errors appear as:
• **F followed by numbers** (F11, F12, etc.)
• **LED light patterns** (number of flashes)
• **Text messages** on digital displays

Note which lights are flashing or the exact code displayed before troubleshooting or calling for service.

Common Error Codes and Solutions

Water Intake Errors (F10, F11)

**F10 - Water Intake Timeout** The dishwasher didn't fill with water within expected time.

• **Potential Causes:**
• Water supply turned off
• Kinked inlet hose
• Clogged inlet filter
• Low water pressure
• Faulty inlet valve

**DIY Checks:** 1. Verify water supply valve is open 2. Check inlet hose for kinks 3. Clean inlet filter (at hose connection point) 4. Test water pressure at nearby faucet

**F11 - Water Intake Too Slow** Related to F10 but indicates partial flow.

• **Additional Considerations:**
• Arizona hard water can clog inlet components faster
• Consider whole-house water pressure if chronic issue

Drainage Errors (F12, F13, F14)

**F12 - Drainage Problem at Start** Dishwasher can't drain water before starting cycle.

**F13 - Drainage Problem During Operation** Drainage failure during a cycle.

**F14 - Circulation Pump Issue** Water isn't circulating properly.

**DIY Checks:** 1. Clean the drain filter (most common fix) 2. Check drain hose for kinks 3. Verify garbage disposal knockout removed (if applicable) 4. Clear any debris from sump area

Heating Errors (F24, F25, F32)

**F24 - Heating Timeout** Water not reaching target temperature.

**F25 - Temperature Sensor Issue** Faulty or disconnected sensor.

**F32 - Water Temperature Error** Incoming water temperature problem.

**Professional Service Typically Needed:** These errors usually indicate component failure requiring technician diagnosis.

Door Errors (F51, F52)

**F51 - Door Doesn't Close** Latch mechanism issue.

**F52 - Door Doesn't Lock** Door lock mechanism failure.

**DIY Checks:** 1. Ensure nothing is blocking door closure 2. Check door alignment 3. Inspect latch for damage

Leak Detection (F70)

**F70 - Water in Base** The float switch detected water in the base pan.

**Immediate Actions:** 1. Turn off power to dishwasher 2. Turn off water supply 3. Carefully pull out unit if accessible 4. Check for visible leaks

**This error requires professional service** to identify and repair the leak source.

Resetting After an Error

For minor errors, reset the dishwasher: 1. Turn off power at breaker for 1 minute 2. Restore power 3. Run a test cycle

If error returns, professional diagnosis is needed.

Arizona-Specific Considerations

Our local conditions can trigger certain errors:

• **Hard water** increases intake valve and inlet filter issues
• **Summer heat** can affect electronic components
• **Power fluctuations** may cause sensor errors
• **Monsoon humidity** can trigger moisture-related errors

Documentation for Service

• When calling for service, provide:
• Exact error code displayed
• When error first appeared
• What you were trying to do when error occurred
• Any patterns (does error repeat?)

Miele technicians can access detailed diagnostics to identify issues quickly when armed with this information.
