Hi, We have multiple GP40 and GP50 systems and a couple of them are having this electronic issue where the pump seems to be pressing the buttons on the control by itself. You can not really control it because the the display is constantly beeping and the cursor is moving around, sometimes changing percantages and/or turning the pump on/off. I replaced the pump display as well as the board that the display is connected to but the problem seems to persist?

I am hoping there is somebody else out there who had experienced the same issue.

Thanks

Hakan
