If you're now wondering how you could solve this problem with your Miele dishwasher, well, here we have the answer for you. Please follow all the steps to the letter and check everything thoroughly to ensure you completely eradicate this fault from your dishwasher:

1. Start with a complete reset to rule out temporary errors in your Miele dishwasher: Before starting what might be complex repairs for you, start with a simple reset. Completely turn off your dishwasher and disconnect it from the power supply for 15 minutes. This process allows for a total system reset, including the sensors, eliminating possible temporary errors or false positives. After the time has passed, reconnect the dishwasher and check if the error has disappeared. If the problem persists, continue with the following steps.
2. Ensure the proper functioning of the drainage pump of your Miele dishwasher: Access the drainage pump, usually located at the bottom of the dishwasher. Check for any objects obstructing it and also verify its correct operation. If the pump is damaged, replace it with a new one that is compatible with your dishwasher model. A filter in poor condition can seriously affect the drainage pump, so checking the filters is also important if you want to ensure proper operation of your dishwasher.
3. Ensure a proper water flow by cleaning the filter of your Miele dishwasher: Locate the water inlet filter and remove it for preventive maintenance. Clean it carefully using a soft-bristled brush, warm water, and a little vinegar to disinfect it. Avoid hard-bristled brushes that could damage the filter mesh. If you notice that the filter is broken, replace it with a new one that is compatible with your dishwasher model.
4. Check that the water level sensor of your dishwasher functions correctly: A faulty water level sensor can send incorrect information to the dishwasher's PCB electronic board, generating an error on the device's screen. Perform preventive maintenance on the water sensor and verify that it works correctly. If you detect malfunctions in its operation, replace it with a new one that is compatible with your dishwasher.
5. Inspect the internal wiring of your Miele dishwasher, and the various drying components: You need to check all the internal wiring of your dishwasher for peeled, cut, loose, burnt, or scorched wires. Make sure all wiring is in good working condition, or else make any necessary repairs. Also, check that the relays are clean and in good operational condition. If you have a multimeter and knowledge of electronics, it's time to put that knowledge to the test. Take the opportunity to also check the components associated with the drying of your dishwasher, such as the heating element or resistance, temperature sensors, and thermostat. Check that these components are in good operational condition and, if necessary, perform preventive maintenance on each one or replace them.
6. Inspect the PCB electronic board as a last resort to find a solution: In rare cases, a voltage imbalance or a short circuit can affect the dishwasher's PCB electronic board. Perform a visual inspection of the board, looking for signs of burns, flashes, burnt resistors, bulging or exploded capacitors, etc. If you have knowledge of electronics and have a multimeter, you can perform a more thorough inspection.
7. Carefully review each step we have mentioned above for an accurate diagnosis: Make sure you have followed all the steps described above to the letter. Do not skip any of them to ensure an effective repair of your dishwasher. If the problem persists, then it's time to turn to Miele dishwasher experts.
