Repair of Halstead Ace High Boiler
Fault was cutting out after 3 seconds when using central heating or hot water.
You would then be left with a flashing LED. This could only be cleared by powering off/on the boiler only for the fault to then repeat.
Troubleshooting claimed this was due to a faulty flow switch.
This was not the problem.
