F7 is a flow meter fault. The flow meter is a device which measures the flow of the incoming water & shows a fault code if not enough water is coming in. Caused by the following:
- Water tap closed during water inlet. (Check tap is fully open)
- Water inlet hose blocked.(Check hose & filter)
- Water inlet valve defective.(If water can be heard coming in then valve is ok)
- Flow meter defective.
