Miele dishwasher repair
A Miele dishwasher wants 7.25 to 145 psi at its supply. Under 7.25 psi it can flag a water intake fault, and above 145 psi Miele calls for a pressure reducing valve. We check the line before blaming a part.

What a Miele dishwasher is telling you
| Message | What it points to | Next step |
|---|---|---|
| Fault F | A technical fault in the machine | Switch off and restart once. If it comes back, book a repair |
| Waterproof fault | The leak protection has tripped | Close the water valve and call for service |
| Water was not pumped away | A blocked filter, a stuck pump or a bad hose run | Clean the filter combination, clear the pump, straighten the hose |
| Water inlet fault | Too little water coming in | Confirm the valve is open and the pressure is above 7.25 psi |
| Intake temperature too low | EnergySaver found the hot feed under 115°F | Check the water heater and the hot line |
| AutoDos or spray arm fault | Trouble with dosing or the spray arms | Write the wording down for us exactly |
Why would a Miele drain itself mid-wash?
Because the house drain sits too low. When the drain connection is below the lower-basket roller track with the door open, water can siphon out while the program runs. Miele's answer is a vent valve on the left cabinet wall. Its membrane has to be pierced on those installs. The hose rules matter too. The drain hose is about 5 ft long with a 7/8 in bore, it may be extended to no more than 13 ft, and the lift has to stay under 3 ft.

How Miele says to clear a stuck drain pump
Unplug
Pull the plug or switch off the breaker first. Miele's steps start with the power off, and the pump area holds standing water.
Filters out
Lift out the filter combination at the bottom of the tub, then bail the leftover water out with a cup or sponge.
Open cover
Press the catch on the pump cover and tip the cover inward. Watch your fingers, since Miele warns that glass splinters collect here.
Turn impeller
The impeller should turn by hand with slight resistance. If it is jammed or spins loose, the pump itself needs a technician.
