Hi JP and Arno . I have the duo 60, it is bonded and I have no corrosion.

I have the Duo 100 aboard and have had problems with corrosion as well. It was most noticeable at the small interconnects between the membranes and caused leakage. I discussed this with the engineer who designed these 2 units.
He said the AMEL bonding system was at fault and the corrosion would end if I omitted the grounding connection. I did this last year and I am pleased with the absence of corrosion. He also mentioned that the bonding issue had been a problem with AMELs but that AMEL would not modify their POV on the matter.
(In future, if I need to replace my water maker, it will not be Dessalator. Their after sales service is so SICK that Lagoon catamorons have dropped them. I feel DESSALATOR is headed to failure)
I'm wondering about a thing after removing my Duo watermaker. I noticed quite some galvanic corrosion despite the fact that the green/yellow bonding wire was attached at several points to the watermaker.
I was actually just in time taking the thing apart as I'm still able to salvage all the important bits.
From traces I could see I'm guessing one of the endcaps on the pump has been leaking also given the amount of salt build-up at the chassis and pump-base.
What I'm wondering about is the bonding sytem. Is it also connected to the shore power earth lead? From earlier conversations I vaguely remember it was not connected. If not then why is the earth connection of the 230 Volt pump connected to the mains earth?
Any advise appreciated.
