# Bosch washer not draining

### The fastest diagnosis is the code

The newer machines write their codes with a colon and a second group of numbers, and the second group is the half that matters — it separates a blocked drain from a supply problem from too much foam. Photograph the whole code.

### A machine designed to be opened

Behind the flap at the bottom front is a pump filter with a short drain spout beside it. It is meant to come out, it needs doing every few months, and almost nobody has been told. A large share of the drain calls we take on this brand end at that filter.

### Stacked in a closet, which changes the odds

Most Bosch laundry here is a 24-inch pair stacked in a closet with the outlet hose running up the back in a couple of inches of space. A hose kinked back there produces the identical code to a failed pump and costs nothing to fix — which is why we ask how the pair is installed before anything else.

The pump filter

Behind the flap at the bottom front, with a small drain spout beside it. Coins, hair grips, lint. The most common answer here by a wide margin.

A kinked outlet hose

Behind a stacked pair with two inches of clearance, this is easy to do and easy to miss. Produces exactly the same code as a failed pump.

The standpipe or trap

Blocked, or the hose pushed too far down it so the machine siphons. The manufacturer specifies a maximum height that installers ignore.

Too much detergent

Foam confuses the level sensing and the machine cannot confirm it has drained. It has its own code, separate from a blockage.

The drain pump

Jammed or failed. A pump that hums without moving water is usually jammed rather than dead, and clearing it is the whole repair.

Unplug it, then open the flap

Bottom front. Have a shallow tray and a towel — there is more water behind it than you expect, and it comes out fast.

Unscrew the filter and clear it

Turn it slowly, let the water out through the spout first if there is one. Rinse it, check the impeller behind it turns freely.

Look at the hose behind the machine

Especially on a stacked pair. Straighten any kink and check how far it goes into the standpipe.

Run a rinse and spin

Short, and watch it through. If it drains and spins, you are done.

There is a filter you can open

What it usually means

Cycle stops with water in the drum

Will not spin because it has not drained

A code beginning E:30 or E:36
