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
- Pressure sensor hose kinked, disconnected, or split
- Small amount of water or debris in the pressure sensor port
- Faulty pressure sensor
Step-by-step fix
- Unplug the machine.
- Locate the pressure sensor (usually a small round component connected by a thin clear hose, near the top of the machine).
- Check that the hose is connected at both ends and has no kinks or cracks.
- Blow gently through the hose to clear any water.
- Reconnect, power on, and run a test cycle.
