what does F:18 mean on my Siemens washing machine?
F:18 on the covered Siemens washing machines is a drainage warning. a blocked outlet hose or pump area needs checking before assuming the filter or motor requires replacement.
model scope: Siemens washing machines displaying the F:18 drainage warning.
disconnect power safely and let the water cool. use the exact manual's emergency draining and removable-cover instructions; do not loosen a cap against a full drum or force a locked door. inspect only the visible hose without moving the connected washer.
the linked filter guide concerns replacing a damaged owner-accessible cap and basket, not buying a filter for every F:18 warning. its 00605010-style assembly includes a fitted sealing ring but not the pump housing or motor. the thread, basket, grip and ring position must match and the cap must seat without force.
stop for a stuck cap, leakage or a flap that will not close. if drainage still fails after permitted care, arrange service.
possible causes
- an obstructed drainage pump area
- a blocked outlet pipe or drain hose
- another fault requiring service after the drain path is clear
