I have an Alkatronic, I bought it as soon as the second production run became available. I used it for a few months and it is an amazing device, however, it was just too loud for my living room.

The device sat unused for a few months while I built a box to contain it (and traveled a lot too).

I am now ready to set it back up, but neither of the large blue pumps (A or C) work. Pump A will make a whining noise when initiated but the rollers will not engage. Pump C makes no noise what-so-ever.

All of the firmware is up to date. The tubes are not clogged.

Can you please provide any advice on how to rectify this? I'm excited to get this device working again.

Thanks!
