The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
There is a filter you can open 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.
- Cycle stops with water in the drum
- Will not spin because it has not drained
- A code beginning E:30 or E:36

What else belongs to the washers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Drain pump blocked
Drain path restricted
Drain blocked or kinked
Water in the base
Dosing pump blocked
Door not locked

About Bosch error code E:00 -18
What this one means
The pump is obstructed.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- The pump unit
- The drain hose
- The drain pipe
What to try yourself
- Clean the drain hose and the pipe it goes into
- Open the pump filter at the bottom front and clear it
Then what
Same family as the other drain codes and the same list of causes. Which number a machine shows depends on its generation rather than on what is wrong.
This code is published for washers. The full list of codes has the rest.
