Morning guys, I'm OTW Iraq
Leaving for London today, sorry Ant, not able to contact you before I go... no email. Not sure when will be back, should be at least 3 weeks.
Mike, please don't use "water wetter".
But if you send yours back, you will likely still get a replacement.
One of my engineers is studing the long term effects of this and other additives, and he will likely REALLY want to look at your unit.
Note: I'm not the expert, but it is my understanding it causes an "ecthing" effect which leads to failures.
But given how you had no noise before it stopped, likely not additives but a bad cord or electronics. We had 2 of the first 500 come back, one didn't fail was just a piece of silicon on the motor cap making noise, the other a bad cord, hence my best guess.
Thanks for the picture, good to see the housing corrosion is no issue even though it is standard anodizing.
For those that don't know about corrosion, this picture is just about perfect
You want to see no "scaring" or white build up around the inlet / out let ports.
There is a small flake which could be some concern if it didn't occur during removal. Otherwise it looks clean and stable. Wish I had a "bad" corrosion picture to show the difference.... only have laptop with me.
Daves around at C-systems all the time, if you need something Ant.
