Possible Causes

Empty or incorrectly inserted water tank, Faulty water level sensor in tank, Blocked water inlet to steam generator, Defective water pump (for tank models)

How to Fix / Troubleshooting

Safety first: Allow the appliance to cool before handling the water system.

Step-by-step checks:

  • Check water tank: Remove, fill, and reinsert the water tank firmly until it clicks into place. Ensure no debris is on the tank contacts or seals.
  • Clean tank contacts: Wipe the electrical contacts on the tank and in the oven with a dry cloth.
  • Run rinse program: If available, run a rinse or cleaning program to flush the water circuit.
  • Listen for pump: Start a steam program and listen for the water pump. If silent, the pump or its wiring may be faulty.

When to call a technician: If F50 persists with a full, correctly inserted tank, have a technician test the water level sensor, pump, and inlet valve.
