No hot water in some parts of house

[Jackie]

I own a top floor flat in a 4 storey block, i bought it 3 months ago (meaning that this is an issue i will have to personally deal with, no landlord). at first i had no issues, but recently, we have no warm/hot water in our kitchen or bath taps. the bathroom sink hot tap gets warm, and the shower water gets hot with no issues at all, but the kitchen sink taps and the bath taps have no warmth to them whatsoever. we are an electric only block and i have no idea where the boiler is/ what water heating system we have. i have an old looking water heating control panel on my kitchen wall, but doesn’t seem to do much even when the light is on.
it’s impossible to do basic things like properly wash dishes or run a bath, really frustrating.
any advise on who i could talk to for help, how i can diagnose/ fix the problem myself, or any general knowledge on this topic would be really helpful for me just now.
thanks

Hello Jackie, are you able to post a photo of the cylinder? If all electric you might be on twin immersion heaters and one could have failed. Is the shower a mixer or electric?
