What it is

The Andrews 7709387 is an upper wiring harness for the single heat exchanger used on Andrews Maxxflo EVO water heaters. It carries the electrical connections between the appliance's control components and the heat exchanger assembly. This loom is specified for the 90 and 120 Maxxflo EVO models.

Signs this part needs replacing

  • Visible damage to the loom, such as cracked insulation, chafing or exposed conductors
  • Scorching, discolouration or a burning smell at the connectors
  • Loose, corroded or heat-damaged terminals
  • Error codes or fault indications relating to the heat exchanger

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list
  • Check whether your unit has a single heat exchanger, as this loom is specified for that configuration
