Baxi Manifold Flow Switch 240667

The Baxi 240667 is a manifold flow switch used in Baxi Bahama 100 appliances. It is mounted in the hydraulic manifold and senses water movement through the domestic hot water circuit, sending the signal that tells the boiler to fire when a hot tap is opened. The part is supplied by Baxi as a direct replacement for the original component in these appliances.

• No domestic hot water, or hot water that only runs intermittently when a tap is opened
• The boiler does not fire on a hot water demand even though the tap is running
• The appliance lights for heating but ignores DHW calls, or drops out shortly after ignition
• Flow switch sticking or failing to register low flow rates, giving inconsistent hot water temperature
• Repeated lockouts or fault indications linked to the DHW circuit

• Confirm the appliance model and GC number against the compatibility list, as the Bahama 100 was produced with both Honeywell and Sit control variants
• Check the previous part numbers 241896, 9102593 and B241896 against the component being removed, as these identify the same item
• Inspect the manifold seals and O-rings while the manifold is open and replace them if they are perished or flattened
