Hello,
Would be great if someone could help me.
Our Oil Warmflow combi boiler UP90HE has started playing up. It has a built in timer(TM-0521 or TM-0522) which allows manual operation of the hot water and heating.
If i manually turn the hot water on, the boiler ignites when a hot tap is turned on.
If i manually turn the heating on, then turn the thermostat up, the thermostat clicks when turned over current room temp. But the boiler does not ignite. The orange finder relay does click. ( I have replaced this relay already)
If i have the heating on and i turn the hot water on, neither work.
I have to turn them both off, then turn the hot water on, on its own.
I had my boiler serviced hoping this may help but now i cant get the heating to come on at all. Before it worked like the hot water did, but only on its own. Now it doesn't work at all.
I do have a spare parts boiler so i thought i would swap out the PCB. As i removed the old PCB from my boiler i noticed some of the soldering on the back had either melted or what it actually looks like is someone has added solder to try and fix a connection. I also noticed there was some burning inside the central transparent relay/switch on the PCB.
At first i thought this was a good sign as it meant there was a problem. But after replacing it with the same board from my spare parts boiler(which looked immaculate) it has not fixed the problem at all.
Other things i have noticed ;
Any help or advice would be good.
Thanks for your time.

If i manually turn on my hot water and heating, the timer/programmer screen dims. This seems to happen when i try to turn the heating on.
On the timer there is a amber light next to the hot water, bu a red light next to heating. This may be normal but thought i best mention it.
When i manually turn the heating on i hear the relay click, if the pump is turned to 2 or 3 i also hear a brief noise from the pump too. if the pump is set to 1 i only hear the click from the relay.
