Miele Dishwasher Fault Codes - Appliance Help Guide

Miele Dishwasher Fault Codes

If your Miele dishwasher is displaying a fault code, the appliance has detected a problem and stopped the programme as a precaution. Miele dishwashers use a built-in diagnostic system to identify issues with components such as the water inlet, drain pump, circulation pump, heating system, door lock, sensors and electronic control modules.

Understanding what these fault codes mean can help you identify whether the issue is something you can resolve yourself — such as cleaning the inlet filter or refilling the rinse aid — or whether professional assistance is required.

Try This First (Quick Reset)
* Switch the machine off at the mains
* Leave it unplugged for a few minutes
* Reconnect the power, switch back on and restart the programme

This can clear temporary faults and save you an unnecessary repair call. Miele recommends this as a first step for most fault codes.

Frequently Asked Questions

Why is my Miele dishwasher showing a fault code?

Fault codes are displayed when the machine detects a problem and stops the programme as a precaution. They are designed to help identify the issue quickly so the correct repair can be carried out.

Can I reset my Miele dishwasher?

Yes — switching off at the mains and leaving unplugged for a few minutes can clear temporary faults. If the same code reappears, the underlying fault will need to be investigated.

Do I need an engineer for every fault code?

Not always. Faults such as F11, F12, F13, F14, F15, F52, F69, F70, F78, F170, F173, F177, F600, F601 and F607 have checks the user can carry out before calling an engineer. Many other Miele dishwasher fault codes are classified as technical faults requiring professional attention.
