What it is

The Ariston 410666 is a handle unit — a lever assembly that forms the flow regulator control knob on Ariston Eureka and Doccia Eureka boiler models. It provides the manual grip used to adjust the flow regulator setting. The part supersedes reference 42891.

Signs this part needs replacing

  • The knob is cracked, split or has broken away from the lever
  • The handle spins freely without changing the flow regulator setting
  • The knob is missing, leaving the spindle exposed
  • The lever has become stiff, seized or difficult to turn
  • The handle no longer grips the spindle securely

Before you order

  • Confirm your appliance model against the fitment list above
  • On Eureka 2000 WT / WC, check the serial number is 4120245 or later
  • Check the existing part for the reference 410666 or the superseded reference 42891
  • Verify the part is the flow regulator control knob and not another control on the appliance

Not sure which part?

Tell the parts assistant what it's going into — the appliance make and model, or the GC number off the data badge — and it will check this part is on the fit list.
