What Drainage fault
actually means.

The PWM 908 stops its program when it cannot empty the drum. Miele names a blocked drain filter or pump and a drain hose fixed too high as the causes, and gives a maximum drain height of about one meter.

What to do when Drainage fault shows on the commercial appliance

Before you book,
in this order.

Each step comes from Miele Professional's own guidance for Drainage fault on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Do not open the door with water in the drum; follow the manual's section on opening the door with a blocked drain.

02

Check the drain hose route and its height behind the machine, which must stay within the limit Miele gives.

03

Cleaning the drain filter and pump means releasing the water in the drum, so if staff have not been shown how, book a visit.

Still there?

It usually turns into dish machine repair. Book with the code and the model number.

What not to do

Questions
about Drainage fault.

Can I clear Drainage fault myself?
Do not open the door with water in the drum; follow the manual's section on opening the door with a blocked drain. If it comes back, it needs a visit.
Why won't the Miele Little Giants door open after a drain message?
There is still water in the drum, and the door stays locked for safety. The manual has a separate procedure for opening it with a blocked drain.
What usually blocks the drain on a Miele PWM 908 in a salon or clinic?
Hair ties, coins and lint are common. Emptying pockets and using wash bags for small items keeps the drain filter clear.
How high can the drain hose be on a Miele Little Giants?
Miele gives a maximum drain height of 3 feet 3 3/8 inches, or one meter. Above that the pump may not clear the drum.

Back to your everyday

Still showing Drainage fault?

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.
