I've got a cpa (motor/pump/heater portion) mounted on a cooler that i've been using as a tempering bath for about 3yrs. The other day, it tripped the gfci outlet while warming up. When i lifted the unit off the cooler to check it out, nasty water with sediment began running out of the seam, any holes and spout. There was a lot in there. I removed the top cover and it appears it had filled itself with water some time ago but the looks of the gunk in there. Since I've had other gfci's go bad, I powered it up on a non-gfi circuit after it dried out. Everything works except for the motor (which i dont use). I ran it for a while and no water seems to be leaking anywhere.
What caused this mess?
