A couple weeks ago I had a small manual DAV seem to go out. It was fully charged, manual light lit up, post raised, but all it would do was 'suck air'. I tried multiple different pre-filled carts (thats all I was using at the time) and still only sucking air. I would take the carts I was trying on it and put them on a different DAV and they would be fine, so I knew it wasnt the carts.
I called CS and got an RMA, so no biggie.
This week I now have had 2 more small manuals 'suck air'. With these I have tried carts, Smileos, and tanks and still only air.
I just dont get it! But I will be calling CS as soon as they are open this morning.
I did take a toothbrush (dry) and ran it around the threads and the post. I have no gunk cause I just started using tanks this week.
Anyone else having any trouble with the small manuals? Or have any ideas for me to try?
