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. Miele Professional commercial appliance display What to do when Waterproof system activated shows on the commercial appliance ### Kind of code Water, 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 to Dish machine repair Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves. ### Shows up as Commercial 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. ### Make Miele Professional Miele Professional machines in a small business laundry are usually visited at the start of the day, before the first full load. ### Source Miele Professional PWM 908 Little Giants laundry machine operating and installation instructions, en-US M.-Nr. 12 805 440 (media.miele.com) Miele Professional PWM 908 Little Giants machines with electric heating and drain pump or drain valve (en-US instructions M.-Nr. 12 805 440). ## Before you book, in this order.

Turn off the water supply to the machine. If it comes back, it needs a visit. ### Can we keep running laundry after the Miele Waterproof message? No. The machine has found water where it should not be, and running more loads can make a leak worse. ### Does the Waterproof system shut off the water by itself? Miele's instructions still ask you to turn off the supply. Do that first, then look for water on the floor. ### Is a Waterproof message urgent in a laundry room? Yes, when water reaches outlets or power cords. Keep people clear and cut the breaker from a dry panel. --- **[Read on the site: Miele Professional Little Giants Waterproof system activated: leak protection has tripped](https://commercialappliancerepair.center/error-codes/miele-professional-pwm-waterproof-system-activated/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
