What it is

The Ideal 075487 is a central heating pressure switch disk, marked Bi1011 111. It forms part of the pressure switch assembly on Ideal domestic boilers, where it responds to changes in system pressure and allows the boiler to prove that the heating circuit is correctly pressurised before it fires.

It is an Ideal Domestic Boiler Spares component used across the Mini C, Mini HE, C95 FF and Europa ranges.

Signs this part needs replacing

  • The boiler fails to fire on a central heating demand while the pressure gauge reads normal
  • Heating runs intermittently, cutting out and restarting without an obvious pattern
  • The boiler locks out or shows a fault after a call for heat
  • The pressure switch does not prove, so the fan and ignition sequence never completes
  • Heating behaviour changes after the system has been drained and refilled

Before you order

  • Check the appliance GC number or serial plate against the compatibility list to confirm the disk suits your model
  • Confirm the part number on the existing component matches 075487 or 1174135
  • Inspect the pressure switch housing and any seals while the assembly is apart, as these are separate items
  • Work on the boiler casing and controls should be carried out by a competent person
