Miele Dishwasher Error Codes — Complete List

Miele G-series dishwashers (G 1xxx through G 7xxx) surface their problems as two-character F-codes, with the intake and drain family doing most of the visible work — F11 means "water won't leave", F12 means "water won't come in or fill correctly", F14 and F78 mean the circulation pump is blocked, and the newer machines sometimes flash the inlet/drain light instead of printing a number. The rest of the map (F63, F70, F78) is deliberately out of the owner's hands: Miele's own pages say "technical fault… cannot remedy yourself," and honest DIY stops at filters, hoses and the drain pump.

• F01 F01 is the dishwasher telling you its water-temperature sensor is short-circuited — the machine will stop heating so nothing comes out properly cleaned until it's sorted.
• F02 F02 is F01's twin on the same sensor: the water-temperature sensor circuit reads open, so the heater stands down and a cycle can finish cold and unwashed.
• F11 F11 means the wash cabinet isn't draining — usually a mis-seated non-return valve, a blocked drain pump or clogged filters, and Miele USA walks owners through fixing it.
• F12 F12 means the dishwasher isn't taking in enough water, and Miele's own support page gives the three owner checks: faucet on, clean the inlet filter, straighten the hose.
• F14 F14 means the dishwasher's circulation pump is blocked — Miele says a pump left unused for weeks or months can dry out and stick, and gives a hot-water soak as the first fix.
• F63 F63 is Miele's 'water path control unit fault' — an internal component fault that Miele's own page says you cannot remedy yourself.
• F70 F70 means the float switch found water in the drip tray and the waterproof system cut the dishwasher off — the drain pump may keep running until you unplug it.
• F78 F78 points at the circulation (wash) pump — a blocked impeller, a connection gone bad, or the frequency converter that drives it — and mostly ends at the technician.
• Inlet/drain light flashing (Intake/drain indicator flashing) When the inlet/drain light flashes, the dishwasher saw a problem supplying or removing water — and Miele's own checklist covers the faucet, the inlet filter and the hose.
