Miele Dishwasher Error Codes

Common Symptoms

• Fault code displayed on the LCD or programme indicator lights flashing a code
• Dishwasher halts mid-cycle and will not continue
• Programme completes but dishes are not clean or still wet
• Water visible in the base or tub after a completed cycle
• Dishwasher runs but water does not heat to the correct temperature

Most Likely Causes

1. 1

   F11 — Drainage Fault

   The dishwasher attempted to drain but water level did not fall within the allowed time window. Primary causes: blocked triple filter (coarse mesh, fine filter, micro-filter), kinked drain hose, or drain pump impeller jammed by debris. F11 is the most common Miele dishwasher fault code and resolves with filter cleaning in most cases. If cleaning the filter does not clear F11, inspect the drain hose for kinks and check the drain pump impeller for obstructions.

2. 2

   F12 — Water Intake / Inlet Fault

   The tub did not reach the required water level within the programmed fill time. Check the water supply tap under the sink is fully open, the inlet hose is not kinked, and the fine mesh filter inside the inlet hose connection is not clogged with limescale or sediment. Low household water pressure (below 0.5 bar) or a partially closed stop valve are the most common triggers for intermittent F12 on Miele G series dishwashers.

3. 3

   F13 — Heating Fault

   The wash water did not reach the programmed temperature within the allowed heating time. This fault points to the heating element, the NTC temperature sensor, or — rarely — the wash pump circulating water past the heater too slowly due to a blocked spray arm. Check the NTC sensor resistance first (see F14 below) before assuming the heating element has failed. Heating element resistance on G series: typically 16–22 Ω.

4. 4

   F14 — NTC Temperature Sensor Fault

   The NTC sensor has returned a reading outside the valid range (open-circuit, short-circuit, or an implausible resistance at a known temperature). At 25°C the sensor should read approximately 10–12 kΩ on most G series models. F14 will prevent the machine from heating water, causing F13 to follow. The sensor is located on the sump body and can be tested and replaced without specialist tools.

5. 5

   F24 — Flow Meter / Water Inlet Quantity Fault

   The flow meter (a turbine sensor in the inlet line) counted a water volume significantly different from what the programme expected. This can indicate a failing flow meter turbine, partial blockage in the inlet path, or a faulty inlet valve solenoid that is not opening fully. The flow meter is located on the inlet assembly inside the machine base and contains a small turbine that should spin freely.

6. 6

   F51 — Circulation Pump Fault

   The circulation pump (wash pump) failed to reach the correct pressure or flow during the wash phase. Causes include a jammed pump impeller (bone fragments, broken glass), a failed pump motor winding, or a blocked spray arm filter restricting recirculation. F51 will often cause poor wash results before eventually halting the programme. Test pump motor resistance: typically 100–180 Ω on G series models.

Quick DIY Checks

1. 1SAFETY: Press the power button to turn off the dishwasher, then disconnect it from the mains supply before accessing any internal component. For F14 and F51 diagnosis involving wiring, confirm no voltage is present with a non-contact tester.
2. 2For F11: Remove both rack tiers. Lift out the coarse filter (counterclockwise twist), the fine filter beneath it, and the flat micro-filter from the sump floor. Rinse all three under running water with a soft brush. Hold the micro-filter to a light — it should be transparent. Reassemble and run a short Rinse & Hold cycle.
3. 3For F12: Locate the inlet hose where it connects to the inlet valve at the back of the machine. Unscrew the hose fitting, remove the small mesh filter with needle-nose pliers, rinse it under running water, and reinstall. Also confirm the supply tap is fully open and water pressure is adequate.

Repair vs Replace

Recommended Tools & Parts

• Miele NTC Temperature Sensor (G Series)

  Two-wire NTC sensor for G 5000 and G 7000 series dishwashers. At 25°C should read 10–12 kΩ. Check your model number (inside door frame) for exact compatibility.

• Miele Heating Element (G Series)

  Flow-through heating element for the sump assembly. Spec resistance 16–22 Ω. Order by model number — element wattage varies between G 5000 and G 7000 series.

  $60–$120

  Buy on Amazon →

• Miele Circulation Pump (Wash Pump)

  Replacement circulation pump for F51 faults where impeller clearing and motor testing confirm motor failure. Pump motor resistance spec: 100–180 Ω.

  $80–$150

  Buy on Amazon →

• Miele Triple Filter Set

  OEM coarse mesh + fine + micro filter set. Replace if the micro-filter mesh is torn, as debris will reach the pump and trigger repeat F51 or F11 faults.

  $20–$45

  Buy on Amazon →

• Miele Inlet Valve

  Single solenoid inlet valve for F12 and F24 faults where filter cleaning and water pressure checks have been ruled out.

  $35–$70

  Buy on Amazon →

• Digital Multimeter

  Essential for testing the NTC sensor (resistance mode), heating element (resistance), circulation pump winding (resistance), and inlet valve solenoid (resistance).
