# Miele dishwasher will not drain

### The fastest diagnosis is the code

Lift out the filters in the base of the tub and check the drain hose still has its high loop behind the machine. If the dishwasher was installed with a new garbage disposal, check that the disposal's knock-out plug was removed — a brand-new machine that has never drained is very often that, and it is not the appliance.

### Most of this is not the dishwasher

The filters, the drain hose loop and the plumbing the machine is connected to account for more of these calls than the pump does. A sink that drains slowly on its own, a disposal installed with its plug still in, or a hose that lost its high loop when the machine was pushed back will all stop a perfectly healthy dishwasher from emptying.

### What the machine tells you

Miele separates draining from filling, so the number on the display already says which half of the water path stopped. If yours reports the water protection system instead, that is a different and more urgent thing: the machine has detected water where there should not be any and has shut itself down deliberately.

The filters in the base of the tub

They lift out and rinse under a tap. Loaded, they slow the drain until the machine gives up on it.

The drain hose loop

Lost when a machine is pushed back in. Without it the sink drains back into the tub.

The disposal plug

On a new installation. The commonest cause of a machine that has never drained since the day it went in.

The drain pump

When the path is clear and the machine still cannot empty. A pump either moves water or does not.

Water still in the tub at the end

What it usually means

Standing water after the cycle

A number on the display and a cycle that stopped

Water that drains if you run it again
