Mend Valve Dhw Working

Divert valve and dhw termistor?

Hi Again
You are right. After cleaning the divert valve all starts working properly but now again heats central instead a hot water, so will buy new valve. I'm from Poland so that is a little delay with delivery infortunately. Also new problem occur it shows DHW thermistor malfunction, so should I replace both of them some time? Thanks for help.
