What it is
The Worcester Bosch flow manifold 87161050930 is the manifold assembly built around the diverter valve section of the boiler's hydraulic block. The diverter valve is a directional water device found in combi boilers, and it routes heated water either to the central heating circuit or to the domestic hot water circuit serving the taps. This manifold carries that valve section and forms part of the waterway assembly on Worcester Bosch 24 CDI combi models.
Signs this part needs replacing
- No hot water at the taps while the central heating continues to run normally
- Domestic hot water runs hot then cold as the diverter fails to hold its position
- Radiators warm up when a hot tap is opened, or heating stops when hot water is drawn
- Water weeping from the manifold or diverter housing
- Boiler locking out or cycling repeatedly on a hot water demand
Before you order
- Check the GC number and model on the appliance data badge against the compatibility list.
- Confirm the part number 87161050930 matches the manifold currently fitted to the boiler.
- Inspect the manifold seals and O-rings, as a seal kit is often needed when the assembly is disturbed.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
