Product Overview
The Baxi Potterton Main Boiler Service Kit (7224763, 5118381, 248733 & 5114725) is a replacement hydraulic and service component kit designed for use within selected Baxi, Potterton and Main heating systems.
This kit contains commonly replaced boiler components, including a 3-way diverter valve assembly, actuator motor, and NTC temperature sensor, which are important for maintaining correct heating and hot water operation. These components work together to control water flow direction and monitor system temperature, helping support reliable boiler performance.
Replacing worn hydraulic and control components during servicing can help restore correct boiler operation and reduce issues related to heating, hot water, and temperature monitoring.

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 3-way diverter valve controls the flow of heated water between the central heating circuit and domestic hot water circuit. The actuator motor operates the valve mechanism, allowing the boiler to switch between heating and hot water demand. The NTC sensor monitors water temperature and provides temperature information to the boiler control system.
Over time, hydraulic components can experience wear, internal scaling, debris build-up, or electrical failure, affecting boiler performance.
Typical symptoms linked to faulty components include:
- No hot water while heating works normally
- Heating operating when hot water is requested
- Intermittent heating or hot water operation
- Incorrect temperature readings
- Boiler failing to respond correctly to demand
- Diverter valve sticking or failing to move correctly
- Temperature-related fault codes
Replacing these service components may help restore correct hydraulic operation and reliable boiler performance.
