What it is

The Andrews 7709388 is a wiring harness for the twin heat exchanger on Andrews Maxxflo EVO water heaters. It carries the electrical connections between the heat exchanger and the appliance control circuit. The harness is supplied as a complete loom for the twin heat exchanger assembly.

Signs this part needs replacing

  • Intermittent ignition or the appliance failing to fire consistently
  • Brittle, cracked or heat-damaged insulation on the loom
  • Corroded, loose or discoloured connectors at the heat exchanger
  • Fault codes relating to the heat exchanger or flame sensing
  • Continuity faults traced to a broken conductor within the harness

Before you order

  • Confirm the appliance model and variant, whether 90/302 or 120/302 and LPG or NG
  • Compare the connector layout and number of plugs against the harness being removed
  • Isolate the electrical supply before removing or fitting the harness
  • Check the harness routing for chafing points that may have caused the original fault
