Question about Water Heaters

Worcester greenstar hot water fluctuation

The boiler is only two years old (28i junior). the hot water wont hold its temperature, i noticed that the green eco button wasnt illuminated and pushed it and the water is better but next time i use it the eco button has gone out again. The pressure looks ok but the heating is always on when i go up there. i have no key to top up but couldnt see the filling loop to fill it up anyway. am i barking up the wrong tree and how do i fill up my system? would love some of your clever help !!!!

Worcester 28i junior , won't come on, I have no heating but have hot water

First check, in there a room thermostat fitted. If not look at the boiler timer if a circular clock type move the side slider to gentral position and set the timed pins do that when the clock face rotates the pins operate the boiler heating on switch OR if a digital type press the button marked mode to so that on the display there indicator bar moves to the on position.
