rvitko said:I don't understand. Does the driver run the pump? Do you mean the connnector where the pump connects to the driver (blue box) inside, or the socket where the transformer connects to the driver- externally accessible. If it wiggles where the transformer plugs into the driver this is normal. The plug is not secured by screws, it is held in place by the three solder points. If it works, that is all that matters.
