Code F2
high severity
Smeg models: Smeg dishwashers have a stainless-steel tub interior. The filter is in the centre of the tub floor, twist-out. The retro colour finishes (Cream, Pastel Blue, Pink, etc.) are cosmetic — the internal components are identical across all SMEG dishwasher colours and finishes.
Common causes
- Inlet valve failing to close fully — machine slowly overfills
- Water level sensor (pressure switch) fault
- Blocked drain causing water to back up
Step-by-step fix
- Cancel the cycle and check whether the machine is full of water.
- If overfull, check the drain first — a blocked drain can cause apparent overflow.
- If the drain is clear, the inlet valve may be failing to close — test by unplugging: if water continues to trickle in, the valve has failed.
