Stanley Brandon 80k m3 not firing heating

[stevieboy2k]

Hi all, hoping someone can point me in the right direction with a Stanley Brandon (oil, with digital display).

I’ve been having a few issues that seem to have escalated:

• Initially, the heating was cycling on for about 3 minutes, then off for 3 minutes repeatedly
• During that time, the radiators were getting very hot very quickly
• Then I started getting Boiler Limit / Oven Limit warnings, followed by Error Code 04 (overheat)
• Now the system has got worse:
  
  • It’s not firing at all (no heating or hot water)
  • The clock/display is showing a strange/random time
  • Controls seem a bit off

Things I’ve tried:

• Turning the system off and back on
• Resetting where possible
• Checking thermostat settings

From what I understand, it could be:

• Boiler thermostat / sensor issue
• Circulation or heat dissipation problem
• Or possibly the main PCB / control board (especially due to the weird clock)

Before I go and spend £300–£400 on a new PCB, I just wanted to ask:

Has anyone seen this combination of symptoms before on a Stanley Brandon?
Does this sound like a PCB failure, or something else I should rule out first?

I’m leaning to main PCB Board being the issue, If it this how old is to replace by a old ish IT Hardware Engineer of 30 years

Any advice or things to check would be massively appreciated

I think your money would be better spent employing an experienced technician on this appliance. There are several electrical circuitry checks needed to identify the failed components before purchasing expensive PCB's.
