Hot water help needed

[Dc19910]

Hi all! Just wanting some help with a hot water problem i have. I would normally just wait and call a plumber out but its Sunday and i really cant wait till tomorrow as i have the first day of my new job tomorrow and really need hot water for shower! Anyway back to the problem.
I have a vallant eco tec plus boiler and the hot water taps and shower is not letting any water out. Cold water is flowing from the taps but thats it. It was fine untill i used the gage under the boiler to raise up the pressure as it had dropped a little, does this often. I forgot which gage it was so i turned both. Then i put them both back so it says close. I have triple checked that i have defiantly closed them. Ever since then my hot water has stopped running. My heating is fine though no problem with that. Any suggestions or advice would be amazing please.

Many thanks.

Try opening the grey knob that you open to top up pressure (just the one on the right hand side). Open up a hot tap. Do you get any water coming out?

I had a vaillant boiler where if you shut that off it shut off the cold supply. Very strange!! Let me k is if that's works please.
