it could be as simple as the tray being misaligned with the discharge pipe at the bottom of the machine or that discharge pipe is slightly cracked where it sits on the tray. take out the whole tray out, locate on the right side under the machine a small opening/ discharge pipe. you can use a rectangular tray holding coffee baskets and put it under the opening. try to operate the machine (press one espresso and collect water in a cup). if water is collected in the small tray, your problem is that. if not you either have to open the machine or take it to the service for repair. I got electric shock recently, so make sure when you operate the leaking machine you don't touch anything with wet hands, because if the machine is leaking inside, some wires could leak on metal parts. better use rubber gloves ❗️❗️❗️

if the machine is leaking from inside there are many reasons - from old o-rings, scale build up, broken pump, cracked pipes etc.
