Water in drip tray

Hello everyoneI
have son problem with my DeLonghi Lattissma Pro EN 750Always
when I take water, or after the milk foam rinse the milk unit, runs a lot of water in the drip tray. When making coffee or latte macciato everything stays dry.
Is this normal, or is there something defective? I just bought the machine used.
I hope you can help me...
Best regards, Frank

Hello,water go in drip tray or coffe container ?
Probably you have a problem with piston circuit,try to remove the coffe container and put a small piece on the pin of the container to see from where water comes
