What it is
The Worcester Bosch 87161461640 is a flow sensor used in Worcester Bosch domestic gas appliances, including the SI II and Junior RSF ranges. It monitors the movement of water through the appliance and passes that signal to the control board, so the boiler can respond correctly to a hot water demand. A working sensor is central to steady ignition and consistent hot water delivery.
Signs this part needs replacing
- No hot water, or the appliance fails to fire when a hot tap is opened
- Hot water temperature that fluctuates or runs intermittently
- Lockout or a fault code appearing during a hot water draw-off
- The appliance runs but does not ignite on demand
- Repeated resets needed before hot water is restored
