Need a bit of advice fitted a vaillant pro in Nov. Cold mains flushed system and then added cleaner and did hot flush then cold flush and fitted instinct filter 2 wks ago vaillant went and plate was partially blocked. They fitted new plate, filter had some dirt in but not as bad as some I have seen. Did another hot flush but hot water is playing up again. Filter has some magnetite in but not much. I think the radiators are breaking down internaly advising customer to change rads. Never had a problem with any other boilers.
