Boiler fault finding and diagnostics

Intermittent faults, fault codes, pressure loss and odd noises traced to the actual cause, so you pay for the repair you need and not for guesswork.

Fault finding & diagnostics

What this covers

Intermittent faults, error codes, pressure loss, leaks and strange noises are investigated methodically rather than guessed at, so you only pay for the repair you actually need. With over 30 years on the tools, I know the common failure points across all the major brands.

  • Fault codes and lockouts that keep coming back
  • Pressure dropping or climbing
  • Hot water fine but no heating, or the other way round
  • Boiler cutting out or short cycling
  • Leaks you cannot trace
  • Noises: banging, whistling, gurgling, humming

How a visit works

The same engineer on the phone and at the door, every time.

You get a two-hour time slot, not a day off work
A call about 30 minutes before arrival
Spare parts for most boilers carried on the van

Methodical, not guesswork

A fault code tells you which circuit tripped, not why. I test the suspected part rather than swapping it on a hunch, because fitting a new PCB to a boiler with a failing fan fixes nothing and costs you twice.

Thirty years of common faults

Every make has its known weak points, from expansion vessels that lose their charge to diverter valves that stick and flow sensors that fur up. Knowing them is what turns a two-visit job into a one-visit job.

Straight answers

If the boiler is near the end of its life and a repair is not good value, I will say so. If it is a ten-minute fix, I will say that too.
