Below are examples of faults people have experienced with their Biasi Riva boiler.


Can anyone help me out diagnosing a Biasi Riva Compact HE Mk2.
HW works fine.
Rads stop heating except bathroom and bedroom (closest 2 to the boiler). Pump is making sounds as if it is working (stops when unplugged)
Flow is hot, return is cold when CH is running. Boiler cycles keeping flow hot,but return does not get warm.
My though is Diverter Valve, but if this is stuck on the HW position, would the flow get hot on this boiler (assume it is dumping heat into the flow by gravity flow)
On the Biasi does the whole diverter need replacing, or just the actuator?
All leads greatly appreciated

hi i posted on this topic before but not sure how i add to it so i have started a new topic..
i have an 8 month old biasi riva advance boiler that has a hot water fault in that the water goes hot then cold and so on, i had a good few replies that were very helpful and all said its probably the he plate blocked as the boiler was not powerflushed when fitted,the pipe work is also the old microbore pipework as i have a victorian i bought a new he plate and today had a plumber to fit it and why he was here he also fitted a fernox tf1 mag filter and all the chemicals that i also the problem is still there??
plumber says leave it a week or so to see if the chemicals and filter do unblock/solve the issue??
if not he says its probably the heat exchanger and its not worth doing due to time and cost…
can anyone shed some more experiance on this for me please….also i know the boiler is still under guarentee so worse case ill get biasi to come out… thanks
