What it is

The Baxi 7213620 is a low voltage wiring harness used in Baxi Ecoblue Advance Combi and Ecoblue System boilers. It carries low voltage signals between the boiler's control components, such as sensors, switches and the printed circuit board. The harness is supplied as a complete assembly with its fitted plugs and connectors.

Signs this part needs replacing

  • Intermittent faults or random lockouts that clear on their own
  • Error codes relating to sensors or low voltage circuits
  • Visible damage to the harness, such as chafed, burnt or brittle wiring
  • Corroded, loose or heat-damaged connector plugs
  • Boiler failing to fire or respond correctly to controls despite other components testing sound

Before you order

  • Confirm your boiler model and GC number against the fit list above
  • Inspect the existing harness and compare the connector layout and plug count
  • Isolate the electrical supply before removing or fitting any wiring
  • Check that the fault is not caused by a separate component on the same circuit
