Baxi Diverter Valve Motor 7211409

The Baxi 7211409 is a diverter valve motor and head assembly, the electrically driven actuator that moves the diverter valve inside the appliance. It is manufactured by Baxi and belongs to the Bahama 100 appliance family, where it controls the changeover between domestic hot water and central heating operation. When the motor receives its signal from the control board, it drives the valve spindle to the correct port so the flow is directed to the right circuit.

• Domestic hot water runs hot and cold, or the appliance delivers heating when hot water is demanded
• The diverter valve head does not move when the appliance switches between heating and hot water modes
• Radiators warm up during a hot water draw-off, or hot water is slow to reach temperature
• The actuator motor is noisy, buzzes continuously or fails to return to its rest position
• The valve spindle stays in one position regardless of the demand from the controls

• Check the GC number on the appliance data badge against the numbers listed above to confirm the correct variant
• Compare the existing motor/head against the alternative part numbers below, as earlier builds used different references
• Confirm whether the Honeywell or Sit control version is fitted, as the two Bahama 100 variants are listed separately
• Have the appliance model and serial details to hand when ordering
