A heat-pump tumbler condenses the moisture from the laundry into water and pumps it away through a drain hose. When that condensate cannot drain, the tumbler shows Check water drain. Miele Professional commercial appliance display What to do when Check water drain 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 PDR 908 HP Little Giants heat-pump tumbler operating and installation instructions, en-US M.-Nr. 12 451 060 (media.miele.com) Miele Professional PDR 908 HP Little Giants heat-pump tumblers (en-US instructions M.-Nr. 12 451 060). ## Before you book, in this order. Each step comes from Miele Professional's own guidance for Check water drain on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Check that the drain hose is in good working order and not bent. 02 Clear the message by opening and closing the door with the tumbler switched on, as Miele describes. 03 If the message returns with a straight, clear hose, book a visit so the condensate pump can be checked. ### Still there? It usually turns into [dish machine repair](https://commercialappliancerepair.center/services/dish-machine-repair/). Book with the code and the model number. ### What not to do Check water drain is about condensate water, not airflow, which has its own filter message. It does not mean the tumbler has stopped heating, although a stopped program leaves the laundry damp. ## What you may notice with it.

Check that the drain hose is in good working order and not bent. If it comes back, it needs a visit. ### Why does a Miele heat-pump tumbler need a drain hose? It condenses the water from the laundry instead of venting it outside, so that water has to go somewhere. The hose takes it to a drain. ### How do we clear Check water drain on a Miele PDR 908? Open and close the door with the tumbler switched on. Fix the hose first or the message will come back. ### Can a kinked hose cause water on the floor? It can back water up in the machine. If you see water near the tumbler, switch it off and check the hose before the next load. --- **[Read on the site: Miele Professional heat-pump tumbler: check water drain](https://commercialappliancerepair.center/error-codes/miele-professional-pdr-check-water-drain/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
