Had a Remeha Avanta boiler fitted some time ago. It really never work properly and now that the weather turned really cold I know this system is not working properly.
3 different technicians from Remeha have paid a visit. each time they seem to blame something different/
The first one blamed the pump. The pump was changed by the instaler even tho the original pump was working correctly.
Second technician changed the microprocessor board.
The third technician changed the heat exchanger as suggested by installer
All three left the boiler on and all rad hot and hot water.
only touble was that when the system was switched off it never came back on. This happened everytime
I managed to get it going one by bleeding the rads.
Last time it was switched off it has never come on.
When switched on the boiler goes over a 3 min venting cycle and then goes onto stand by mode and nothing happens. there;s no heating or hot water.
The last technicia suggested the system is losing water, but there's no evidence of that anywhere.
When trying to bleed the rads little air comes out and water only trickls out.
One suggestion is that the cold water feed pipe is partially blocked as the system fills in quite slowly if drained, but even so when the system has water the boiler should function correctly.
The system was not power flushed when the boiler was installed.
The Remeha technicians seem to suggest that the boiler goes into stand by mode because there's not enough water pressure or no enough water in the system hence they siggested it could be a leak.
Is there a pressure sensor on those boilers? could it be faulty?
Has anyone got an idea what could be at fault here? I've been without heating for nearly two months now.
TIA
