What it is

The Ravenheat flow detector switch RIV150050 is a sensing switch used in Ravenheat gas boilers. It detects water flow through the appliance and signals the control system accordingly, forming part of the boiler's demand and ignition sequence. It is listed under switches within Ravenheat gas boiler spares.

Signs this part needs replacing

  • The boiler fails to fire or recognise a hot water or heating demand
  • Intermittent operation, with the appliance cutting in and out without a clear cause
  • No pump or fan response when a tap is opened or a heating call is made
  • Fault codes or lockout conditions relating to water flow detection
  • Visible damage, contamination or sticking at the switch

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the existing switch and its part number before removal
  • Verify whether your boiler is natural gas or LPG, as fitment differs by variant
  • Isolate the appliance and follow the manufacturer's guidance when replacing
