Code
F15
What it means
The water inlet is blocked or restricted.
What you can check
Open the stopcock if it is closed, take any kinks or loops out of the inlet hose and clean the inlet filter without dunking the plastic housing, then reconnect gently.
When to call a technician
A technician is needed if F15 stays, if the inlet hose is damaged, or if flow pressure at the connection is below 50 kPa and a plumber cannot resolve it.
Quick things
Look at the tap first: an unopened stopcock is the simplest cause. Then trace the inlet hose for kinks or loops and take them out. Keep checking the hose from time to time, because it can weaken, and a damaged one has to be swapped by way of Miele customer service.
The filter
Power the dishwasher down, take the plug out of the socket and turn the stopcock off. Never immerse the plastic housing of the connection, as an electrical valve is inside. Detach the water intake valve, slide off the seal, and use combination pliers on the filter bar to pull the filter free. Rinse, reinsert with the seal, reattach to the stopcock and turn the water on gently. A dripping joint wants tightening. The filter must always be back in place.
The supply
If flow pressure at the connection is lower than 50 kPa (0.5 bar), speak to the facility manager or a plumber.
