MVP V3 center pin spring

[Wakefulpanda]

So I recently purchased an MVP 3. The center pin is supposed to be spring loaded but mine is getting stuck when depressed. After I unscrew an atty (subtank nano) and then put on my K4 it won't read the atomizer.

I try to push down on the center pin after removing the subtank and it appears to be stuck down. I then have to pull it back up with a screwdriver.

Has anyone else had this issue?

This was an issue with the original MVP which I owned. I often had to use a nail file or precision screwdriver to tease the 510 center pin up to make contact with my juice delivery device.

You may want to clean your MVP's center pin connector with some isopropal alcohol (higher % the better) in case some old juice has gunked it stuck. Other than that, you might contact your vendor that your MVP has a defective 510 center pin.

Man this actually worked! I only had it a day and I was ready to send it back. Looks like there was some black gunk, maybe machine oil on the pin. Little rubbing alcohol freed it up. A million thanks to you!
