DHW IS VERY POOR UNLESS CENTRAL HEATING IS SELECTED, I SUSPECT THE DIVERTER VALVE IS PASSING AS THE FLOW IS GETTING HOT. DO I NEED TO REPLACE THE WHOLE VALVE OR IS THERE A QUICKER (CHEAPER) SOLUTION.
MANY THANKS

you can just replace o rings to check if its diverter thats faulty turn isolation taps under boiler off and see if hot water is ok
