Could anyone tell me why the DHW on my boiler is not hot enough. The temp is set to max and the burners are lit and there are no fault lights on.

I have the same problem though in my case the red LED on the front panel is flashing. I need to replace the DHW sensor, when this sensor fails the boiler will carry on supplying hot water but restricts it to 64degs cent. only. It does this by using the flow sensor and CH sensor to regulate the temp. at the taps
