I have a worcester 28CDI, diaphragm has been replaced in diverter valve, and has worked for two weeks, boiler is firing up on microswitch, but hot water seems to be going to central heating, if i isolate flow and return on heating, i have hot water from taps. :?:

Merely replacing the diaghragm will not fix it if the lower part is jammed.

You should call back the engineer and get him to fix it properly !
