what should i check when my Bosch washing machine shows E:18?
on Bosch washers using E:18 for drainage trouble, debris around the pump/filter or a restricted outlet path can be involved. let retained water cool before any permitted maintenance.
model scope: Bosch washing machines displaying the E:18 drainage warning.
use the exact model's controlled draining and filter instructions with the power disconnected and tap closed. check an already-visible outlet hose without moving the machine, and do not force the main door or a stuck cap. persistent failure needs further assessment.
the linked filter-replacement guide is relevant only if the removable cap, basket or sealing ring is damaged. an intact obstructed filter may only need cleaning. for WAP28482AU/01, check cap clearance and service-flap closure; do not select a cap for another WAP revision from the range name alone. a cap that will not seat or a service flap that will not close needs a fit check, not force.
first checks
- prepare for controlled draining
find the exact e-nr instructions, allow cooling, close the tap and disconnect safely before loosening the filter.
possible causes
- debris obstructing the pump/filter area
- a restricted outlet hose or waste connection
- another drainage fault if cleaning does not restore operation
