What it is

The Worcester Bosch 87120001160 is an on/off control knob for a range of Worcester Bosch and British Gas-badged RSF appliances. It mounts on the control panel and turns the appliance's on/off switch, giving the user direct control over the boiler's operating state. Supplied as a serviceable spare, it restores positive, tactile operation where the original knob has worn, cracked or come loose.

Signs this part needs replacing

  • The knob turns freely on the spindle without operating the switch
  • Cracks, splits or missing sections in the knob body
  • On/off markings worn away or no longer legible
  • The appliance does not switch on or off when the knob is turned
  • The knob has worked loose or detached from the control panel
