No problem, now, the blue box is the driver- that got hot or the transformer? The transformer is the black hockey puck and if that is hot, it likely will work again after it cools down, it has a safety shut off if it gets too hot. The transformer would get hot if the pump was stopped by a blockage.

The most usual cause is water damage short of that there are two possible causes.

The first scenario is an assembly issue and the transisitors did not contact the heat sink material (aluminum body) sufficiently to dissipate the heat and burned themselves out. The second scenario is the pump got dirty repeatedly and shut off and alarmed repeatedly so the transistor warmed up and cooled and the repeated expansion and contraction loosened the screws at the top and the contact to the heat sink. Either scenario is pretty rare.

Just send me the driver and I'll replace it as long as it isn't a water damage issue.
