Hi,
I think I am heading for an early grave!!!
I am having a nightmare sorting out this system! Any advice would be greatly appreciated.....
My model of boiler is a Vaillant Eco Tech plus 637 r1
History....
The boiler has been recently serviced (two months ago) and had a new F75 error pressure sensor V3 fitted after problems with that. All was good for a few weeks. Then the hotwater would work, the heating would not. A new Wireless thermostat receiver was fitted, and the heating started to work - problem solved, but NOW....
Regardless of if I want hot water, or heating, both, or just one or the other (using the Honeywell timer switch) the boiler fires, runs for about 3-4 minutes, then turns off. The flame goes out on the screen, all that is left is the icon of the pump (round circle with triangle in it) and the radiator icon, and the temperature - on the LCD screen.
Then the pump icon goes out, then the Rad icon goes out and I am left looking at the temperature reading (30ish) and nothing on the digital screen at all.
When I try again, everything off and on, from master spur swithc, the pump light comes on, then the rad icon appears, then I hear a cluncky click sound and the pump icons disappears, and then appears 10 seconds later, I hear the same clunk and out it goes again. After a few more clunks, the icons all go out, and all that is left is the Temperature.
I cannot believe what aggro I have had with this system.
The pressure is good at 1.0bar for cold, and the twisty temperature controls on the front are in the right positions.
Also to add, I did replace the Honeywell timer recently, vainly trying to fix the F75 - which has been sorted. So I think I can rule out the timer as well.
There are no error displayed for my latest issue.
If ever there was a product, I wish I had avoided 7 years ago - this is the one!!!!
Any advice would be great.
Regards,
Richard.
