# Bosch dishwasher drain repair

### The most common call on this brand

A Bosch dishwasher that will not drain is the single thing we are asked about most, and it has an unusually good ratio of easy causes to expensive ones. The filter assembly in the floor of the tub and the drain pump cover beside it are both designed to be removed by hand, without tools, and between them they account for a large share of what we find.

### Three names for one condition

The manufacturer has labelled this differently across three generations of machine, and all three are still in South Florida kitchens: a two-digit code in the twenties, a four-digit code, or — on a model with no digital display — a pattern of flashing lights above the door. They are the same condition and the same list of causes.

### What decides the figure

- A blocked filter or a loose pump cover: the visit, and nothing else
- A blocked or kinked hose, or an air gap full of debris: the visit plus a little time
- A drain pump that has failed: the part, and usually the same visit
- A machine plumbed into a new disposal with the knockout plug still in place: an installation problem rather than a repair, and we will say so

What this involves

Filter, pump cover, hose and air gap

Drain pump replacement where it is the pump

Tested on a full cycle before we leave

The filter and the pump cover

Both come out by hand, and between them they explain most standing water. We do this in front of you so you can do it yourself next time.

Then the path out

The hose, the high loop, the air gap and the disposal knockout plug — a machine plumbed into a disposal that still has its plug in has never drained and never will.

The pump itself

If the pump is drawing current and not moving water, or not drawing at all, that is the part. It is a well-designed replacement and usually same-visit.

A full cycle, watched

We run a cycle through to the drain and watch it finish. A drain repair signed off on a rinse is a repair signed off early.
