I was using my 50l rotovap from lanphan when I noticed the flask was a little loose so I shut down the speed control box. When I hit the off bottom I heard a click sound and didn’t think anything of it.
I tightened the flask and proceeded to turn the control box back on only for it to show this error “Eo”
Anyone have ideas on what this error could mean and went possibly wrong?
It could be a relay, not sure how the machine works but if a relay fails it can still click. Is there a panel you could open to take a look at what’s going on?
I opened the panel and took a look, nothing looked wrong with it. I did had a relay burn out in control panel for the heat bath on this rotovap a while back and it was pretty obvious and melted.
