Not working 2022 bizerba vsp. Screen will only boot up sometimes and when it does, it says “communication error" it could be a simple fix. I just don’t have the knowledge or time to try and fix it. When the unit is plugged in the green light on the light adjustment knob lights up and when you press the green button I hear clicking coming from underneath the unit. I’m just trying to sell it for what I paid for it at the auction.
