Miele dishwasher F12 / F13 / F15: water inlet blocked or restricted
THE SHORT ANSWER
Water inlet blocked or restricted
Miele gives F12, F13 and F15 the same owner checks for restricted water entry: faucet, inlet filter, hose and supply pressure.
Check that the supply faucet is open and the visible inlet hose is not kinked.
F12F13F15The inlet connection contains an electrical valve. Never immerse its housing; unplug and close the faucet before disconnecting it.
WORK THROUGH THE BASICS
Safe troubleshooting checks
Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.
Correct accessible kinks gently and watch the affected area for damage. Do not keep using a weakened or leaking hose.
What to noteThe hose is unobstructed and dry.
With power disconnected and water closed, follow the illustrated filter instructions. Rinse the removed filter, reinstall it with its seal correctly seated, reconnect and open water slowly.
What to noteThe filter remains installed and the connection does not drip.
Miele identifies flow pressure below 7.25 psi (0.5 bar) as a supply issue. A facility manager or plumber can assess it.
What to notePersistent faults with adequate supply receive Miele service.
YOUR NEXT DECISION
When to stop and get help
