PCB Dead? Hot water/No Heating Engineer wants £2500

Hello

Hoping for some advice to save me £2500 as I not that knowledgeable but think I know what I need to do.

First issue was we had no heating but did have hot water.  Got my mate out and it looked like it was the connection from the thermostat dial not making contact.  To get round this we wired it so it bypassed that and was controller by the switch on the boiler on/off/timer etc.

That worked fine for a while until the heating would stay on even if I turned the switch to off or timer and also not come on when I turned it on…was totally random but at least we had heat.  The heat then stopped for a few months and then just came back on again but heat was randomly coming on.  Now I can’t get any heat again and the pilot sometimes comes on for a few min and thought it’s time to find out why.

Had someone out to look and as you can see there are 4 LED lights and no LED screen read out.  They engineer said the board will cost £500 and cheaper to just get a new boiler.

Edit: says I cant post external links or emails for 7 days. Please contact the forum administrator for more information.  But you can copy and paste that address please imgur.com/a/IiaE49k




Even though I don’t know much I don’t believe him.  Has anyone had a similar experience? I found someone who will repair the board for £45 so thinking of trying that first.  I did see the thread on the capacitor repair process on here but I am not very confident doing that. https://gledhill-repairs.forumotion.net/t969-pcb-fault-fixing


Was warned by technical support not to buy off the internet or refurbished boards...


Thanks very much 

Search on here for murray Martin my heating went last Christmas and I got a refurb from murray fitted it. Touch wood it’s worked better than it has in years. I did fit two new pumps and valves at the same time but my dad’s looked at the old pumps since and said they were ok. I will be getting another pcb in the new year as a spare. Just in case as in my case everything seemed to point to the pcb being at fault all the way along.

Hi
It sounds like the ACB
GT 155
But you may have other problems.
Check fault codes once board fitted.
Also check For&E tank
Check boiler pump is ok too.
Check unit casing for any leaks or stain marks.
Bottom right is one of the places.
If you put your location /area someone may be local to you.

Thanks very much for all the advice. I am in Newcastle if you do know anyone that would be amazing

Hi the ACB is definitely in a fault state I can repair it for you or provide a reconditioned ACB as well. For details have a look at my website www.murraymartin.co.uk There are also some videos on there that might be of interest.

The ACB is relatively easy to swap out as it plugs into the system.

Sorry Also posted a new topic as the board has been fixed now

Had my PCB fixed by https://gledhill-repairs.forumotion.net/t2141-pcb-dead-hot-water-no-heating-engineer-wants-2500 so cheers for that. Boiler downstairs light is on and I now have hot water!!

Thermostat is up to full and all the 3 pumps are boiling hot HL1,2,3 lights all on and the LCD display says

--
- ON

The radiator in the bedroom near the boilermate 2000 is hot but I can still hold my hand on it and not burn and the rest don;t seem to be heating. Was going to check the pump as people have suggested but just wanted to make sure this could be the reason and what should I be doing to the pump?

Thanks for all the help btw!
