Washer-dryer will not drain; water remains in the drum, and F05 is displayed.

Safety: Unplug the machine. Keep towels and a shallow tray ready for any water spillage.

• Clean pump filter: Open the lower access flap. Slowly unscrew the pump filter cap and allow water to drain into a tray. Remove debris such as coins, lint, or buttons. Ensure the pump impeller spins freely.
• Check drain hose: Inspect the external drain hose for kinks or blockages. Detach it from the standpipe or sink trap and flush it through with water.
• Test drain pump operation: With the filter reinstalled, plug in the machine and select a drain or spin cycle. Listen for the pump running. If it hums but does not pump, the impeller may be jammed or the pump could be worn out. If it is silent, the pump or its wiring may be faulty.
• Inspect pressure system: If the tub drains but F05 persists, clean the pressure hose and chamber as described for F04. A stuck pressure switch can falsely report water as present.
• Replace pump if needed: If the pump coil is open-circuit or the impeller is damaged, replace the drain pump assembly with a compatible Hotpoint unit.
