Baxi Diverter Valve Maxflow Combi 247395

The Baxi 247395 is a diverter valve assembly for Baxi Maxflow Combi appliances. It forms part of the boiler's hydraulic group and controls where the heated primary water is sent. When a hot water tap is opened, the valve moves to route boiler output through the domestic hot water plate heat exchanger; once the tap closes, it returns flow to the central heating circuit.

Because it sits between the two operating modes, the valve has to move cleanly and seal properly in both positions. Wear, scale or a failed actuator motor will show up as poor hot water performance or unwanted heating.

• Hot water runs lukewarm or cold while the central heating is running
• Radiators warm up when only a hot water tap is opened
• No hot water at the outlet even though the boiler fires and the pump runs
• The diverter actuator motor sticks or fails to travel, often flagged by a fault code
• Inconsistent performance when switching between heating and hot water modes

• Check the GC number on the appliance data badge against 47-075-03 to confirm the model.
• Compare the valve already fitted with part number 247395 to confirm the correct assembly.
• Cross-reference the alternative number 1116292 when checking older documentation or stock records.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
