What the F53 Fault Code Means
The F53 fault code indicates a fault with the circulation pump speed sensor. When the circulation pump is running, the speed sensor monitors its rotation and reports this data to the control board. If no signal is received from the sensor while the pump is activated, F53 is triggered. Miele confirms this is a technical fault that cannot be remedied by the user.
Common Reasons This Fault Appears
Faulty speed sensor
The speed sensor on the circulation pump may have failed and is no longer providing a signal to the control board.
Circulation pump blocked
A foreign object or debris blocking the circulation pump impeller can prevent the pump from spinning and cause the speed sensor to report no movement.
Wiring fault
A loose or damaged electrical connection to the speed sensor can cause it to stop reporting to the control board.
Control board fault
An issue with the main electronic control module can affect its ability to read speed sensor data correctly.
Safe Checks You Can Try

Switch the machine off at the mains and leave it unplugged for a few minutes. Reconnect the power, switch back on and restart the programme. A power reset can sometimes clear a temporary fault.
Miele advises that if the fault persists after a reset, the appliance cannot be repaired without professional assistance.
