The symptom this code usually arrives with

About Bosch error code E:00 -18
What this one means
The pump is obstructed. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
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 of them, searchable, including the labels older and newer machines use for the same conditions.
