rumbles then stops - no hot water! TRIED EVERYTHING!

Im moving house in 2 weeks and need this working

At first no lights on anything (timer, circuit board or green/red light). Electrician got electrictity going to circuit board (now the red light on this flashes).
Then electrician bought a now Grasslin timer and installed that so now the lights on this work.
The next day the vertical radiator looking component began to get damp - wiped it down and seems fine now.
The boiler started to rumble but then stopped and wont start again... then randomly did restart and now wont - assumed it had tripped but when i checked the reset button it was still flush. Now it won't start no matter what i do. On just checking... it seems the 'Cold in from mains' pipe and 'Hot water to taps' pipe are also wet (not dripping, more like cold condensation that keeps coming back)

I feel like its one step forward two steps back! Any advise would be greatly apprecaited! The water is still ice cold and we move in 2 weeks!

Thanks Guys

You have 2 heaters one must be working?
If the unit is hot.
Run a tap, pump runs and that is it.
Get the unit hot first.
Checked the water level?

Check the water level and then the pump. This is difficult to give advice on as we cannot see the unit.

Have you moved yet?
