Alex, from time to time I have to give an extra tap to my joysticks to get them back to the center. You can try flicking the valve closed with a little more force, and also rotating the joystick a bit when your machine is turned off so a different part of the mechanism is being locked.

That black hose connects to the expansion valve as well as the vacuum breaker. Is your machine fully warmed up? If it continues to do this then your vacuum breaker may not be fully sealing. If a steady stream flows out of that black hose when a plumbed machine is sitting idle, or when a machine running in reservoir mode is pulling a shot, then the expansion valve likely either needs to be opened up and cleaned, and possibly adjusted tighter.
Please loop in firstname.lastname@example.org so we can provide you the best information and instructions to get back up and running.
And FYI Ken, our tech department hasn't experienced any issues related to overfilling the reservoirs (or the machines getting wet inside). The parts you're referring to are covered by a stainless steel partition that separates the reservoir from the internals.
