What it is

The FLOW SWITCH GT 413 A / 414 A is a De-Dietrich flow switch used across the GT boiler family. It monitors water flow through the appliance circuit and signals the boiler control accordingly. It is specified for GT 413 A and GT 414 A models and is shared with a number of other GT series appliances.

Signs this part needs replacing

  • The boiler does not fire when there is a call for heating or hot water
  • Intermittent operation or lockout during a draw-off
  • Domestic hot water runs cold despite the boiler being powered
  • The boiler fails to register flow in the water circuit

Before you order

  • Confirm the appliance model on the boiler data badge matches one of the fitments listed
  • Compare the part number on the existing flow switch with the part number shown here
  • Check the connection type and wiring on the existing switch against the new item before fitting
