Re: Marco UP6/E pump and MASS+ light

Salt water is almost certainly the cause for a short circuit between the pumps electrical supply and the case and hence the bonding system. The other, less likely, possibility is accumulation of carbon dust from worn brushes. 

The solution is to disassemble the motor, clean with fresh water, dry, spray with CorrosionX, and reassemble.
