Don't know this boiler that well, but it does have an electrically driven motorised valve as the diverter and a separate flow switch.
If you're right in saying that it's OK on heating (CH), but noisy on hot water (DHW), I would guess that the pump might not be operating in DHW mode. But if you want to have a crack at fixing this yourself, you'll need a copy of the manual.
