Symptom
Bosch washer not draining
A cycle that stops with water in the drum, or clothes left soaking because the machine never got to the spin. There is a pump filter behind a flap at the front of these machines, and almost nobody knows it is there.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
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.
Installation & re-fitting from $185 -
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.

Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
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.
-
02
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.
-
03
Look at the hose behind the machine
Especially on a stacked pair. Straighten any kink and check how far it goes into the standpipe.
-
04
Run a rinse and spin
Short, and watch it through. If it drains and spins, you are done.
How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.
If the display is showing something
- E:30 / -80 Drain path restricted
- E18 Drain blocked or kinked
- E:00 <-> -18 Pump obstructed
- E18 Low water level
- E:36 -25 -26 Drain pump blocked

About 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.

Before you book
Questions about bosch washer not draining
Can I really open the pump myself?
Yes — it is designed for it and it is in the manual. Unplug the machine, have a tray ready, and take the filter out slowly.
It drains but will not spin.
Often the same problem later in the cycle: these machines will not spin on top of standing water. If it drains fully and still refuses, the question moves to the door lock and balance detection.
How often should I clean the filter?
Every few months is plenty, and it takes five minutes. It is the single most useful piece of maintenance on this machine.
