What it is

The Baxi 5108961 is a timer harness cable supplied for the Baxi Platinum Combi ErP boiler range. It provides the wiring connection between the boiler's control PCB and an external timer, and is specified for installations where no integral timer is fitted. The harness carries the switching and supply connections required for the timer circuit.

Signs this part needs replacing

  • The timer fails to switch the boiler on or off at the set times
  • The boiler does not respond to the external timer at all
  • Visible damage, scorching or chafing on the harness cable
  • Loose, corroded or cracked connector plugs at either end of the harness
  • Intermittent timer operation that changes when the harness is moved

Before you order

  • Confirm the boiler model is a Baxi Platinum Combi ErP
  • Check the boiler serial number ends in DC or EC, as listed above
  • Inspect the existing harness connectors and PCB terminals for damage
  • Verify that the installation uses an external timer rather than an integral one
