A couple/three weeks ago my potable fresh water
pump died. Specifically it started out as the water
pump breaker popping after maybe a minute or so (but the pump still working while the breaker was on) and then it stopped completely. I checked voltages at the pump leads and they were fine. I decided the pump was dud (also a Jabsco
Sensor Max 14) and installed the replacement. Replacement worked fine and in my eyes this proved the pump to be dud. About a week ago, I took the dud pump home, hooked it up to a power supply and wonders of wonders, it worked fine. Made a mental note that maybe the motor
has a sticky spot or something similar and brought the old pump back to the boat as an emergency
spare. Forward to today, I open the faucet and no water ...... damit !!!! The problem is exactly as before. There is power to the pump but the motor
doesn't turn on. I disconnected the output hose from the pump in case there was a plumbing
issue but no, there was no pressure.
I could make an assumption that both pressure sensors were bad ... but this is a brand new (10 years old but new in the box) pump and the chances of both pumps having the exact same symptoms seems remote
Has anyone run into this before? Are the sensors on these prone to failure and it's my lucky day or am I somehow missing something here ?
