Hotpoint Aquarius FWD60 causes trip switch turn off randomly?

I tilted it to backwards. Roughly 2 liters of water run out of back corners. Now at the moment I press the power button, that same blue switch trips. What should I do next? Which panel to pop off? Will it be dry by itself without popping off anything?

Thanks you very much for your help.

I think it's RCD. Because it is blue and placed separately from all the black ones.
I'll try what you said and will write the result.

Thank you for detailed answer :)

You've not said whever it's the MCB for that individual circuit on your fuse board that's tripping, or the RCD that covers most or all of your circuits. I'll make the assumption that it's the RCD that's tripping which would mean you probably have an earth leakage. There are multiple conditions that could cause this, but the first place to check is the tray at floor level. Check this is not flooded by pulling machine out and tipping it to see if water runs out of the base. If this is the case, pop a panel off and dry it out to see if this solves the problem.
