Hi I have a 38cxi the heating works but no hot water i have changed the internal parts on the diverter valve installed a new heat exchanger and replaced the actuator but still no hot water there are no error codes and its at 1.2 preshure
Please does anyone have any idea where to go next
Thank you for your time
 
Do you know if it’s sensing a hot water demand? Could be flow turbine/sensor. Was the actuator new? Did you confirm the diverter was at fault or just sling the parts in with fingers crossed?

Hi thank you for your reply all parts were new as it turns out the actuator is working i kept it I put the old one backon on when the hot water is on the boiler does not fire up if its the sensor how do you test it ?
 
Test it with a multimeter with tap off and then tap on. Information can be had from Glow worm online resources or Glowworm technical helpline. Does sound like the flow sensor though.
