What it is

The Ariston 571053 is a water flow switch used in Ariston Jupiter Hx series appliances. It detects water movement through the domestic hot water circuit and signals the appliance to fire when a tap is opened. It is a service component for the Jupiter Hx range.

Signs this part needs replacing

  • The appliance does not fire when a hot tap is opened.
  • Domestic hot water is intermittent or cuts out during draw-off.
  • The appliance fires without a demand, or fails to modulate correctly on hot water.
  • The switch shows signs of scale, debris or mechanical wear on inspection.
  • Fault codes or lockouts relating to water flow detection appear on the appliance.

Before you order

  • Confirm the appliance model and edition against the fitment list above.
  • Check the part number on the existing component or against the manufacturer's parts list for your appliance.
  • Inspect the flow switch housing and connections for scale or damage before fitting a replacement.
  • Verify that the fault is with the flow switch itself and not with the pump, diverter or water supply.
