I have an Ideal Isar boiler - it's approx 4 years old and installed by the previous owner.
I noticed the other day that when in central heating mode the diverter valve clicks constantly. In DHW mode this doesn't happen.
On closer look the valve positioner is constantnly stoking open and closed.
I removed the actuator head and found that the cam is constantly turning.
Would anyone be able to guide me as to whether the actuator or control board is at fault?
Thanks for your help,
Lucy
