When the drain pump cannot empty the wash cabinet, the machine stops with an alarm and the word Drain. Miele points to the filter combination, the drain pump and kinks or loops in the drain hose. Miele Professional commercial appliance display What to do when 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 PFD 101 U / PFD 102i commercial dish machine operating instructions, en-US (media.miele.com) Miele Professional PFD 101 U built-under and PFD 102 i integrated commercial dish machines (en-US operating instructions); the PFD 401 U and PFD 404 U fresh-water machines are sold alongside them. ## Before you book, in this order. Each step comes from Miele Professional's own guidance for Drain on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Turn the machine off. 02 Clean the filter combination in the wash cabinet as shown under Cleaning the filters. 03 Check the drain hose behind the machine for kinks or loops, and book a visit if Drain returns after the filters are clean. ### 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 Drain is a pump-out problem, not a leak; a leak trips the Waterproof message. Water standing in the cabinet at the end of a cycle without any message is usually the same cause in a milder form. ## What you may notice with it.

Turn the machine off. If it comes back, it needs a visit. ### Why does our Miele Professional stop with Drain during dinner service? Food waste packs the filter combination fastest on busy nights. Cleaning the filters between rushes prevents most Drain stops. ### Is it safe for staff to clean the Miele drain pump? The manual includes an owner procedure for the drain pump with the machine off. If staff are not comfortable with it, book a visit. ### Can a loop in the drain hose cause Drain? Yes. Miele lists kinks and loops in the hose, which slow the pump-out enough to stop the program. --- **[Read on the site: Miele Professional Drain: the dish machine could not pump out](https://commercialappliancerepair.center/error-codes/miele-professional-drain/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
