What it is

The Ariston 61307845 is a temporized fuse rated at 250V and 0.315A. It is a time-delay fuse used on the control side of Ariston and Chaffoteaux gas boiler PCBs, where it protects the circuit from overcurrent without tripping on brief inrush surges. It is listed as a gas boiler spare for the appliance families below.

Signs this part needs replacing

  • Boiler is completely dead with no display or indicator lights.
  • No response to a call for heat or hot water.
  • Fuse shows no continuity when tested with a multimeter.
  • Visible scorching, blackening or a broken element inside the fuse.
  • Fuse blows again immediately after replacement, pointing to a fault elsewhere in the circuit.

Before you order

  • Confirm your boiler model against the fit list above.
  • Check the rating and type markings on the existing fuse match 250V, 0.315A and temporized.
  • Isolate the electrical supply before removing or fitting the fuse.
  • If the fuse has blown more than once, investigate the underlying circuit fault before fitting another.
