I own 4 MP10 pumps. One of my oldest started flashing red and green. Found a piece of egg crate jammed in in. Let it cool down and nothing changed. Opened the dry side found some debris in it. Like the paint on the magnet is pealing. It now runs for about 30 seconds and then the controller goes dead. or flashed red/green. I am sure it will need servicing. Was not sure if there is a flat rate on these now that the QD's are soo much cheaper...
