I’m trying to help a friend diagnose why his Spectra 340 water
maker has stopped working. The initial supply pump
which lifts the raw water
up to the pump
module appears to working OK. The high pressure pump inside the pump module is making a humming noise
but nothing like the noise
my pumps make on my Cape Horn system. In turn, the Clarke pump isn’t operating properly and only gives a half-hearted whimper thump every 30 seconds or so. My best guess is that the high pressure pump is faulty and not supplying the Clarke pump with enough pressured water
...but it’s only an educated guess.
I’d welcome any input.
