What it is
The Worcester Bosch 3 Port Valve Body (HSV3) is a hydraulic component used in Worcester Bosch combi appliances. It sits in the water circuit and directs flow between the central heating side and the domestic hot water side, so the appliance can switch between the two duties on demand. This listing covers the valve body under part number 87161084860.
Signs this part needs replacing
- Domestic hot water runs lukewarm or cold while the heating circuit stays hot
- Radiators heat up when only hot water is called for, or hot water runs when only heating is called for
- The valve head moves but the body does not change the flow path, so demand is never satisfied
- Water temperature at the tap fluctuates sharply as the valve fails to hold position
- Visible scale, debris or leakage around the valve body port connections
Before you order
- Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list before ordering
- Check the part number on the existing valve body and compare it with 87161084860, 1020409 and BS50755
- Inspect the mating seals and O-rings on removal, as these are commonly disturbed when the body is separated from the manifold
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
