Water that moves in a Miele W1 when it should not is unlikely to be siphoning, because Miele built the washer with an anti-siphon gap: in a floor drain a minimum drain height is not required, and the drain pump has a 3.2 ft (1 m) delivery head. The manual's drain rules are still worth checking: the hose must be free of kinks, laid around a sink edge and secured, or inserted into a 1 1/2 in (4 cm) standpipe and secured so it cannot slip, and the drain hose fixed too high (over 39 3/8 in) leaves water in the machine. The Service Water-proof system message means the water protection system has activated: close the faucet and call Miele.

Model-specific
What is true of this model and not of its siblings
- Miele's water protection system
- The Miele W1 has a water protection system on its inlet hose; when it activates the display says Service Water-proof syst. and the manual tells you to close the faucet and contact Miele Technical Service. It is a safety feature that shuts off water when a leak is detected, so the message should never be cleared and ignored.
- Inlet hoses and filters
- The inlet hoses are 63 in long with 3/4 in female threads and are pressure-proof to 1,015 psi (7,000 kPa). A filter sits in the open end of each hose and another in the intake point; neither may be removed. Replace a hose only with a genuine Miele hose.
- Miele parts for this problem, part numbers and prices
- Miele's own shop lists the drain hose, part number 10103861, at $27.00, a longer drain hose, part number 11820221, at $61.00, and the suds container sealing ring, part number 11086752, at $85.00 (prices change). A drain hose that has slipped or kinked is the first thing to check, since the water protection message is a safety shutdown, not a part failure.
