Stern did me right with a correct fix. It is a power supply issue. If your machine is a PRO model, they are shipped with a 320W 48V PS. The LE and PREMIUMS come with 500W 48V PS. Swapping the 320 to a 500 ensures that the machine can handle the addition power requests on mods we add. Solved my Kiss machine issue instantly. Only about $120 to swap out but the most important Mod for a PRO model.
