What the F52 Fault Code Means
The F52 fault code indicates that a sensor has detected an excessive amount of foam inside the appliance, causing the wash programme to be interrupted. Miele confirms this is typically caused by using too much detergent, the wrong type of detergent, or an excess quantity of rinse aid — all of which can be addressed by the user.
Common Reasons This Fault Appears
Too much detergent
Using more detergent than recommended for the wash load or water hardness level is the most common cause of excess foam in dishwashers.
Wrong type of detergent
Using hand washing-up liquid or other non-dishwasher detergents in the machine will produce large quantities of foam that will trigger this fault.
Excess rinse aid
Overfilling the rinse aid dispenser or using too high a rinse aid dosage setting can contribute to foam build-up.
Faulty heater pressure switch
In some cases, a faulty heater pressure switch can cause the machine to incorrectly register foam conditions even when detergent usage is normal.
Low pump pressure
If an item has tipped over and retained water, reducing the volume available in the wash circuit, pump pressure can drop and cause a false foam detection reading.
Safe Checks You Can Try
Reduce detergent quantity
Check the detergent manufacturer’s recommendations for your water hardness level and load size, and reduce the amount used accordingly.
Use only dishwasher-specific detergent
Ensure you are using a detergent specifically formulated for automatic dishwashers. Never use hand washing-up liquid.
Check the rinse aid dosage
If the rinse aid dosage is set high, try reducing it via the dishwasher settings menu.
Check that no items have tipped over
Open the dishwasher and ensure all items are securely positioned. Hollow items such as cups and bowls should be placed upside down.
Restart the dishwasher
Switch the machine off at the mains for a few minutes, then switch back on and restart the programme.

When To Contact A Professional
If the F52 fault persists after reducing detergent and checking the load, there may be an underlying fault with the heater pressure switch or circulation pump that requires a qualified engineer to investigate.
Internal components should only be inspected or repaired by trained professionals.
