The fault

When your boiler shows a fault code

A fault code is the boiler telling you which circuit has a problem, ignition, pressure, a sensor or the fan. The same code can mean different things across Worcester, Vaillant, Ideal, Baxi and other brands, so it needs interpreting correctly.

Note the code and the make and model before you call, it helps us arrive with the right parts and fix it faster.

What a lockout usually points to

  • Ignition or flame-detection fault
  • Low water pressure lockout
  • Faulty fan or air-pressure switch
  • Failed temperature sensor (NTC)
  • Condensate blockage or PCB fault
