Code F9
medium severity
Samsung models: Samsung front-load pump filters (WF series) are behind a push-open panel at the lower-right of the front fascia; top-load models (WA series) have no user-accessible filter. The SmartThings app can read active error codes on Wi-Fi-enabled models and often clarifies which sub-component triggered the fault.
Common causes
- Partially blocked pump filter reducing flow
- Drain hose routed too high, increasing back-pressure
- Pump impeller starting to wear
Step-by-step fix
- Clean the pump filter (see OE steps above).
- Ensure the drain hose peak is no higher than 100 cm from the floor.
- Run a drain-only cycle and listen for the pump — a healthy pump sounds steady, a worn one may pulse or whine.

Prevention
- Clean the filter monthly.
- Do not route the drain hose higher than specified in the installation manual.
When to stop DIY
If drain performance is slow even after clearing the filter, the pump is wearing and should be replaced before it fails completely.
