MP40 Question

[Kevotron]

Had a little incident in which water made contact with the mp40.
Power supply adapter still has a green light but when plugged into the interface, the unit barely lights up to almost nothing at all.
looked everywhere online and only the Dry side motor or power supply being the only replaceable part.
anybody want to chime in to as what I can do to get it back working as I don't want to spend another $500 on a new pump.
