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?

Does it click when you’re trying to use it?
Yes I do hear a click when I try to power it on.
Sounds like the gears are misaligned. I had an issue on my re501.
Look in the tricks of the trade. I put the fix in there.
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?
Thanks I’ll check that thread out. Sounds like that’s what may have happened since the flask was loose.
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.
Do you have access to a wiring diagram? If you’ve had a relay fail before I’d take a glance, unless the machine is good to go now.
