What it is

A flow switch manufactured for Andrews water heaters, carrying part number 7876379. It detects water movement through the appliance circuit and signals the control system when flow is present, allowing the burner to fire safely. It is listed within the Andrews hot water spares range.

Signs this part needs replacing

  • The appliance fails to fire despite water being drawn and the pump running
  • Burner locks out or shuts down shortly after ignition
  • Intermittent operation, with the unit running only at certain flow rates
  • Fault code or diagnostic indication pointing to a flow or water detection fault
  • No switching signal at the flow switch terminals when flow is present

Before you order

  • Confirm the part number 7876379 matches the label or parts list for your appliance
  • Check the appliance model and serial details against the Andrews water heater documentation
  • Inspect the wiring connections and the switch paddle or sensing element for debris or damage before condemning the part
  • Verify that the fault is not caused by low flow, air locks or a blocked strainer upstream
