whirlool tub leak help!

About a year and a half ago I remodelled my upstairs bathroom. Among other things I installed a whirlpool tub.
The other evening I was watching television and at the back of my mind I heard an unusual sound--at the time I though it was a fan blade making a whirring noise. A short time later I got up and while walking to the kitchen i noticed water was coming through the drywall ceiling directly below my upstairs bathroom. I shut the main water valve off in the basement. The next day I shut the valves off that control the water that goes to my tub and shower and turned the main water on and no water leaked. Today I cautiously turned the water back on to the tub and shower and no water leaked.

I am not about to turn the whirlpool tub on.

I am speculating that a hose on the whirlpool tub sprung a leak and the sound I heard was the pressure being released. Is the water in the tubes in a whirlpool tub under pressure when the tub is turned off?

Maybe a seal or something blew in the pump.

I have a hatch at the back of my tub apron that opens up that gives me access to the pump and I don't see any specific location where it is leaking.( its been 2 days since the leak). I cannot see all of the tub tubes from the hatch so I cannot
see a tube that is leaking. If it is a tube leak I will have to dismantel my tub apron which I tiled over.

Any suggestions on what I should do next?
