Hi Steve, I am not a plumber but have done a lot of DIY on my own heating system with Worcester Bosch combi boiler! I believe that you can have the hot water on without the heating system filled, just turn all the settings as for summer use and the thermostat right down so the heating is forced to stay off!

SOURCE: flashing red light on Worcester 24i junior combi boiler

Pressure is ok? at 1 bar or above
I think on this one there should be a reset button [red] on the left hand top of the casing - or lower the control panel [ phillips screw on each side] and the button is on the left of the base plate. Press this and try the heating.or hot tap
P.S. if you're on a prepayment meter check you have gas.

Testimonial: "Thank you, very helpful advice. Still got the plumber coming to check everything over but the boiler is up and running for now. Thank you so much"

NO!!! DO YOU HAVE A MONOFLOW ONE PIPE WITH 2 TEES, OR A SINGLE PIPE LOOP GOING IN AND OUT, OR 2 PIPE SUPPLY AND RETUUN SYSTEM ? ZONE VALVES OR SEPERATE CIRCULATORS ? EATHER WAY BOILER WATER NEEDS TO CIRCULATE FROM SUPPLY TO RETURN. JUST FINISH WHAT YOU STARTED.

Hello, I have a Worcester 24i boiler and the heating is working fine but the hot water will only stay hot for about a minute at a time in the kitchen sink, the shower is ok but only when the heating is on....

http://homeguides.sfgate.com/flush-out-tankless-hot-water-heater-53060.html
The link is to how to flush a tankless system.
This should be done once a year.

This link is to the manual on the unit.
On my unit, it the hot water is running slow the unit turns off and the hot water goes cold, so for me its run the water on full.

My worcester bosch 24i junior pressure keeps dropping if i have heating off for an hour i have to top up boiler and reset also when i have heating on the pressure jumps right up to over 4.0bar

When water is heated it expands. To deal with this all boilers are fitted with a small expansion vessel which is like a reservoir which holds the excess water.

This expansion vessel is like a balloon in a metal pot. When the water goes in the metal pot the baloon squashes a bit to make room for the extra volume of water. When it cools the balloon pushes the water back into the heating system.

What has happened is your expansion vessel no longer works. When the water heats up there is nowhere for it to go so the pressure jumps up to 4 bar. The Worcester boiler lets high pressure water escape (most boiler allow this to go through the safety valve at say 3.5 bar).

When the water cools the pressure drops very low as the volume of water contracts.

The problem is your expansion vessel - normally a little red painted metal cylinder inside the boiler.
