Glow worm 30cx dhw fault

[Nigel Cutler]

dhw runs for a few minutes as normal, then runs cold. Flip out the the connection to the flow turbine, then reconnect, dhw returns to normal. Then it goes back to same fault. Same if I shut down the hot water then open back up again.

No codes flashing, heating working fine, dhw thermistor replaced. I'm suspecting pcb? Any one else experienced this?

Tried calling Glow-worm technical, can't get through.

Flip out the the connection to the flow turbine

What are you proving doing that ? flipping out ????

 

[Nigel Cutler]

That it's not the flow turbine playing up?

if its the black and grey turbine suspect it strongly, if its the all black one probably look somewhere else
