Vokera Linea hot water problem

[Deleted member 32524]

Hello,

Above boiler when shower runs cuts out at 38 deg, CH shows 90 deg when I close the filler loop. Thought partially blocked DHW. Flushed through pump head twice with chemicals, still same prob. Thought maybe primary thermistor fault? Cant get to it to test it, cant get a reading on board. No 07 code though.

What are the thoughts on Primary themistor fault or new dhw plate? Or both? Or something else?

Thanks for the help.

Thanks everyone. DIVERTOR was the issue. Service kit sorted it. I was about to waste my time going to my olds garage and digging out an old 15/50 head to try that.

Wish I had looked there first!! Got a spare service kit now and will keep that in mind. I appreciate the help from everyone.
