Vaillant Ecotec+ 837 - no hot water

[Tom Craig]

Please let me know if you can advise.
I checked the boiler and saw the water pressure needed a little topping up.
I turned the two valves underneath and the pressure went back up.
However, when I turned the valves back, there was no no hot water.
I've tried turning the two knobs again but the hot water's still not come back on.
I've also tried using a screwdriver to turn the screws, but that hasn't worked either.

Thanks

What are these screws that you have turned?

Are you totally sure you have turned the valves to the original position?

What am I meant to think when you say "no hot water" ??? Nothing out of the hot taps at all? Or cold water coming out of the hot taps?

What does the display show?

are you getting the tap sign in display when running hot water ??
which two knobs are you turning ? if on filling loop why turning again when pressure reads ok already ?? or are you turning the knobs on the front ??
if problems getting pressure back up the knobs underneath can round off and keep spinning with no effect , you need to explain your problem properly so it makes sense so people can help you. are you getting tap sign in display with hot tap on ?
if pressure is adequently adjusted and by the sounds of it i would advise you get a repair gas engineer

The handles on the filling loops on these are prone to failure. Undo the screws, pull the handles off and use a spanner to open the valves

Often the strong plastic knobs from washing machine valve will fit!

Far cheaper!
