Water flying out

I have a multi-split system. One indoor unit has water not dripping but flying out of it. When I opened up the cover to inspect, water was dripping onto the roller fan. That explained why the water was sent flying out.

Above the roller fan is the coil-fin assembly. When I poured some water onto the coil-fin assembly directly above the roller-fan, I noticed the water dripped straight through to the roller fan. The two should be kept water-tight from each other, right? And my problem is that whatever that is separating water from the two is leaking?
