The MP20 driver has an internal breaker that will shut off the pump if it senses too much load. What is happening is the bearing which is comprised of the driveshaft in the ceramic bushing is getting tight. If you take the wet side apart, and can not easily separate the two, that is the problem. You can soak the parts and work them apart to where they are free. Call EcoTech support and talk to them about it. There are upgraded parts available that may help this. Running in Lagoon (purple)mode will be better.
