Frequently Asked Questions
Common questions about Bosch E18 error
E18 is the most common Bosch front-load error code. It means the washer could not drain within its time limit, and nine times out of ten the culprit is a clogged pump filter. You will find the filter behind the small service flap at the bottom front of the machine. Bosch recommends monthly cleaning to prevent E18 from coming back.
Open the small service flap at the bottom front of the washer. Inside you will find a drain plug and the pump filter cap. Place towels and a pan under the opening, slowly unscrew the plug to release water, then unscrew the filter. Clean it under a tap, removing all visible debris, before reinstalling it firmly.
