Just an FYI should anyone come here looking for help on this:
When removing the dispenser bottle from the dispenser holder from the "home" position the dispenser holder can lift slightly from the gantry and the pressure switch can get stuck under the dispenser holder. If this happens when the unit is off and you go to power it on the dispenser holder will jam and make quite a racket as it tries to find the "home" position with the switch stuck under it.
Turn the unit off, tilt the dispenser holder up enough and slide it away from the pressure switch, let it back down, and then power back on the unit and it'll be fixed. I attached a picture of what the right and wrong ways look like if this happens.
