What Waterproof system activated
actually means.
The laundry machine carries the same kind of water protection as Miele's dish machines. When it reacts, the program stops and the owner is asked to turn off the water supply; there is no owner reset, because the cause is a leak.

What to do when Waterproof system activated shows on the commercial applianceKind of codeWater, fill and drain
Water is not arriving, not reaching its level, not heating or not leaving on time. A dish machine may be short of fill because a supply valve is half closed or its line strainer is clogged, it may drain slowly through a scrap basket full of debris, or its booster may be too scaled to heat the rinse; a combi's steam generator may be scaled or its water treatment exhausted; a washer-extractor may time out on a slow drain. Opening the supply valve, cleaning strainers with the unit off and checking the drain line are fair; a pump, a fill valve, a heater or a leak near wiring is a visit.
Usually leads toDish machine repair
Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves.
Shows up asCommercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display
A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

Before you book,
in this order.
Each step comes from Miele Professional's own guidance for Waterproof system activated on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Turn off the water supply to the machine.
If water is on the floor near outlets or the machine's power connection, keep people clear and switch off its breaker from a dry panel.
Book a visit so the leak can be found before the machine is used again.
What not to do
This is a leak signal, not a drainage problem, which has its own message. It is also different from Machine is leaking, a reminder that points to the machine or its drain valve and is confirmed with OK.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
