I was wondering if anyone had problems with their water pump not turning on. Before it stopped working, I also realized it was fluctuating in pressure (after reading about these pumps…they have a variable speed motor and should keep water pressure pretty constant. Our Cyclone has a Shurflo 5.7 5900-0201 pump. After testing all the electrical, I realized that there was something else wrong (Also a note: the pump has a 2nd fuse next to it) I removed the pump and took the top piece off that holds the pressure sender/switch where there is a very small hole that allows water to pass to the sensor. I then turned on the pump and forced water out of the hole (thinking there may be something stuck). Put the pump back together and was working again. My questing is…..Has anyone had a sensor go out or do these pumps get clogged that easily. I really don’t want to put the pump back in if it needs to be replaced.
