Boiler does not heat hot-water cylinder, after bleeding rads

[Frank Gary]

I have an old glow worm 45-60b I bled the radiators in the house because of noise then found out the tank in the attic was empty.Fixed that then found I had no hot water.The radiators were working fine but no hot water.water pressure is fine
On the hot water.Any help please.

So it’s not heating the water?

It's heating the water in the radiators not the water in the hot water cylinder.

when you bleed the HIGHEST radiator in the house, does water squirt out forcefully, and without dying away?

Is the cylinder higher or lower than this radiator?

Air locked cylinder coil . Have a look for a manual air bleed valve on the hot water coils pipework ,near the cylinder.
