What it is

The Andrews current leakage safety device (part E758) is a safety component used in Andrews Fastflo water heaters. It is listed for Fastflo Lwh42, Lwh56, Wh42 and Wh56 models. Its role is to provide protection against current leakage faults within the appliance.

Signs this part needs replacing

  • The RCD or RCBO trips when the water heater is switched on
  • The appliance repeatedly loses power or fails to operate
  • A burning smell or visible heat damage is present around the safety device
  • Intermittent electrical faults that clear after resetting the supply
  • An earth leakage test indicates a fault within the device

Before you order

  • Confirm your appliance is an Andrews Fastflo Lwh42, Lwh56, Wh42 or Wh56
  • Check the existing part number and reference 240 EJSJ022
  • Ensure the fault is with the safety device rather than external wiring or another component
  • Consult a qualified heating engineer if unsure about diagnosis
