What it is

A 3.15A time-lag (T) glass cartridge fuse rated at 250VAC, measuring 5mm x 20mm. It is supplied by Biasi as part number BI2145106 and protects the electrical circuit on Basica COND M275V series appliances. The fuse interrupts the supply if current exceeds its rating, preventing damage to the boiler's control and power circuits.

Signs this part needs replacing

  • The appliance is completely dead with no display or indicator lights
  • The boiler loses power immediately after the supply is switched on
  • A continuity test across the fuse shows an open circuit
  • Visible scorching, blackening or a broken element inside the glass body
  • The fuse blows again straight away after being replaced, indicating a fault elsewhere in the circuit

Before you order

  • Confirm the rating on the existing fuse matches 3.15A, T type, 250VAC
  • Check the physical size of the fuse holder accepts a 5mm x 20mm cartridge
  • Isolate the electrical supply before removing or fitting the fuse
  • Investigate the cause of the failure before fitting a replacement, as a fuse is a protective device rather than a fault cure
