What it is
The pipe flow sensor with O-rings is a Main component for the Multipoint FF range of water heaters. It monitors water flow through the appliance so the control system can respond to a hot water draw-off. The assembly is supplied complete with its O-rings for sealing on fitment.
Signs this part needs replacing
- The appliance fails to fire when a hot water tap is opened
- Hot water delivery is intermittent or cuts out during draw-off
- The burner ignites and then shuts down shortly after
- Water weeps from the sensor body or around its O-ring seals
- Flow-related faults recur after the sensor has been cleaned
Before you order
- Confirm your appliance is a Main Multipoint FF or Multipoint FF ErP
- Check the model and GC number on the appliance data badge against the fit list
- Verify the existing sensor part number is 5111380
- Inspect the O-ring seats and pipe connections for damage before fitting
