I'm having problems heating only the water with the boiler. When i have heating & water set it works fine, but when i try to heat the water only, the heater goes off & the light to show sanitary demand never comes on.

Clearly a fault !

If its a heat only boiler then perhaps a motor valve problem.

It's more likely to be the diaphragm in the domestic hot water flow switch.
This is situated on the right hand side hydro bloc and is a diy fix.

Look to see if the pin moves out of hydroblock behind flow switch, if it does not diaphagm at fault, and could be microswitch but more than likely diaphragm
