What it is
The Baxi 247502 is a DHW flow switch adaptor kit manufactured by Baxi for its Combi HE range. It carries the flow switch that monitors water movement through the domestic hot water circuit, so the boiler recognises a hot water draw and fires to heat the water. The adaptor mounts the switch in the DHW side of the appliance, where it responds to changes in flow as taps are opened and closed.
Signs this part needs replacing
- The boiler does not fire when a hot tap is opened, leaving no domestic hot water.
- Hot water is intermittent, or the temperature at the tap fluctuates during a draw.
- The boiler fires briefly on a hot water demand and then shuts down.
- A fault code relating to DHW flow or water sensing appears on the appliance display.
- Scale, debris or a sticking switch mechanism interrupts reliable flow detection.
Before you order
- Check the appliance model and GC number on the data badge against the compatibility list before ordering.
- Confirm whether the previous part number 246229 is the number currently fitted to the appliance.
- Check whether a gasket or seal is needed for the DHW manifold joint when the adaptor is replaced.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
