What it is
The Worcester Bosch water pressure switch, part number 87161051110, is a replacement sensing component used across the manufacturer's Junior RSF boiler range. It monitors water pressure inside the appliance and closed system, switching its contacts to allow or restrict flow according to the pressure it reads. The switch sits within the boiler's control chain, so its readings directly influence how the appliance responds to changes in internal pressure.
Signs this part needs replacing
- The boiler fails to fire on a hot water or heating demand
- Intermittent lockout that clears on reset but returns shortly afterwards
- The pressure gauge reads normal while the appliance behaves as though pressure is low
- The pump runs but the boiler does not progress to ignition
- Water pressure related fault codes appear on the appliance display
Before you order
- Confirm the GC number on the appliance data badge matches one of those listed above.
- Compare the existing switch against the alternative numbers 1014445, N5924 and WB87161051110 before ordering.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
