I've had my duetto for probably four years. I admittedly havent used it in probably a year. I ordered some coffee so decided to get my machine ready. I turned it on and it stays on for a few seconds. The PID lights up, see the boiler lights blink then after a few seconds the PID turns off. You can hear it click and go off. The light on the main switch stays on though. There is water in the reservoir and I do see the float float up so don't believe it thinks there is no water. Anyone have any ideas?

Figured it out. It was in fact the magnet. When I cleaned it I pushed down the float stop (for lack of a better term) so the magnet was floating but not as high as it needed to be.
