Baxi Main Potterton Diverter Valve Motor 7216534 – Replaces 248733, 5132452 & 710188301

Product Overview

The Baxi Main Potterton Diverter Valve Motor (Part Number: 7216534) is a replacement actuator designed to operate the 3-way diverter valve within selected Baxi, Main and Potterton combination boilers.

The motor drives the diverter valve, controlling the direction of heated water between the central heating and domestic hot water circuits. This allows the boiler to respond correctly when switching between heating and hot water demand.

Part number 7216534 replaces the earlier references 248733, 5132452 and 710188301 in applicable installations.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please check the available options from the dropdown menu.

Technical Insight & Common Failure Symptoms

The diverter valve motor operates the internal 3-way valve mechanism. When domestic hot water is requested, the motor moves the valve to prioritise hot water production. When the hot water demand ends, the valve can return to the appropriate central heating position.

A worn or faulty actuator motor may prevent the diverter valve from moving correctly.

Typical symptoms associated with a faulty diverter valve motor include:

• No or inconsistent domestic hot water
• Radiators becoming warm when hot water is being used
• Boiler failing to switch correctly between heating and hot water
• Intermittent hot water operation
• Diverter valve failing to move correctly
• Motor making unusual buzzing or clicking noises
• Reduced heating or hot water performance

Replacing a faulty diverter valve motor may help restore correct switching between the central heating and domestic hot water circuits.
