TLB: Performed an operational test of LH overwing EMERG EXIT outside access flap - success.

The exit will not give-in to spray pressure while still locked. However, the external access flap is designed for a push from outside, innit?

Looking at the external photo of the door in the above link it starts to make sense that the water pressure was strong enough to push the ‘push to open’ handle. It does appear that the water pressure from the hose was too much for the handler to cope with. But, would the slide not disengage if the hatch was opened from the outside?

Are you not just a little skeptical about this "fact"?

Don't think it was someone holding a hose! Think monitor and not well controlled.

The amount of force that this water cannons can generate is beyond belief ... Takes a tremendous amount of force to project water, of which 1 cubic meter weighs 1000 kgs, to a distance of 80 or 100 meters. I wouldn't want to be at the receiving end of it, even at a distance of 100 meters ...

Some years ago there was an incident with a Delta 767 in a maintenance hanger that had an "automatic" fire supression system that, for whatever reason, was inadvertently activated. Cabin windows were pushed-in and, needless to say, there was water everywhere inside of the aircraft. Can only imagine the cost to repair everything on that aircraft ...
