Can't increase boiler pressure on Ideal Classic 2 combi

[WarV9]

I bled a couple of radiators in the house earlier but the heating and hot water stopped soon after. The boiler pressure is now at 0 but I cannot seem to increase it. The valves underneath don't do anything, despite this working for other boilers I've had in the past. Any idea what the issue is? According to the manual, all the valves are currently open which is strange. Bought this house 3 months ago and the heating and hot water has been fine until now

Is the filler loop in cupboard below ?.

Doesn't have thre integrated fill loop that are found between the right 2 valves (blue and black) on Ideals

Must have a braided hose type loop somewhere between the cold water pipe and the central heating pipe - look for something similar to this.

No internal filling loop on this boiler.
Look for external one.
Silver braided hose with black lever valve at one or both ends.

So we actually found the external loop in the storage under the stairs. But thanks, we would have known what to look floor thanks to all the responses!
