| Error Code | Meaning | Common Causes & Solutions | | :--- | :--- | :--- | | | Drainage issue / Water remains in the machine. | – Check & Clean : Filters, drain pump, and non-return valve are often clogged. – Inspect : Drain hose for kinks or blockages. – Potential Part Fault : Faulty water level sensor. | | F12 / F13 | Water intake problem. | – Check : Ensure the water tap/stopcock is fully open. – Clean : The water inlet filter (situated where the hose connects to the tap). | | F14 | Heater pressure switch fault. | – Check : The water level relative to the filter handle; it may indicate the heater switch isn't being depressed, suggesting a water level issue. – Potential Part Fault : Defective heater relay or insufficient water. | | F24 | Heater relay fault. | – Often related to the heating element or its control circuit. – Potential Part Fault : Heating relay. | | F70 | Waterproof System activated (leak detected). | – Immediate Action : Turn off the stopcock and disconnect the machine from the power supply. – Inspect : The base tray for water. A leaking water inlet valve or a cracked water distributor part is a common culprit. | | F84 | Internal electronics / Communication fault. | – Try : A simple power reset by unplugging the machine for a few minutes. If the fault persists, professional diagnosis is needed. | | FXX | General technical fault. | – Action : Turn the machine off and back on after a few seconds. If the indicator lights continue to flash, contact Miele Service. |

The service manual, on the other hand, is a technical document intended for qualified service technicians. It contains wiring diagrams, component specifications, error code definitions, diagnostic flowcharts, disassembly instructions, and detailed repair procedures. Miele does not typically make service manuals publicly available, as repairs should be carried out by Miele-authorised technicians for safety and warranty reasons. However, official service documentation can sometimes be obtained through Miele’s dealer portal or by contacting Miele technical support directly.

If the error persists, more advanced diagnostics may be required, including testing component continuity with a multimeter, inspecting the pump pressure level switch for foreign objects, and examining the circulation pump impeller for blockages. For the F14 error in particular, checking the water level after three minutes of operation is recommended—the water should stand at least four millimetres above the coarse filter in the centre of the filter combination.
