I'm glad to hear you got everything resolved. That's great! I had a tech out years ago for those plastic bits getting stuck. Since I've replaced the holder, no issues, but I know there's great online resources to permanently fix it (I never used the height adjust anyway).
I've checked and re-verified all connections at the PCB and took a look at the control panel. Still no luck with the flashing "CE". At this point, I'm going to try a replacement control board because the new ones should fix that annoying power button issue that I've never planned to get fixed.
