What it is

The Ariston 560166 is a diverter valve for the domestic hot water (DHW) circuit, supplied with a microswitch. It is used in Ariston gas boilers to direct water flow between heating and hot water operation. The microswitch is included as part of the valve assembly.

Signs this part needs replacing

  • No domestic hot water, or hot water runs cold while central heating continues to work.
  • Central heating operates when only hot water is demanded.
  • Hot water temperature fluctuates or drops during use.
  • The valve does not move between heating and hot water positions.
  • The microswitch does not operate, so the boiler does not detect a DHW demand.

Before you order

  • Confirm the boiler model and serial number against the fitment list.
  • Check the GC number where shown on the appliance.
  • Verify the existing valve is marked 560166 and has a microswitch.
  • Confirm the appliance is an Ariston gas boiler covered by the listed models.
