The freshwater pump on my 2005 330 Express stopped working. Reset the freshwater rocker switch and examined pump which seemed fine. Any other thing I may be missing other than replacing the pump? Thanks!
 
On my 2005 the freshwater pump would fail to pump occasionally. I finally figured out it was the pressure switch. If I left the system pressured up after a trip and did not pull the trigger and let off the pressure then sometimes the pressure switch would stay depressed and not let the pump work. Usually I could bang on the pump head and it would start working. I finally took the pump apart and figured out how the switch worked. I replaced the switch only and never had another problem. Its worth a look to see if the switch is your problem before you buy a complete pump. Just jump 12 v around the pressure switch and see if the motor runs.


This is where I got my replacement switch...

Those pumps go every 10 years or so. I'd just change the entire thing out. Very easy once you locate it and not expensive to buy the replacement.
