Spectra 400 Watermaker

[LivingWater54]

I have a Spectra Newport 400 watermaker that was just serviced. It has 15 hrs on it, we made one tank of water fine all went well. Started it two days later in the same water, it started fine, the numbers were good and then the salinity number went over 800 and the feed pressure went to 60PSI. Looked up troubleshooting and the possibility of the feed pump is the problem. It has 15 hrs. on it am I missing something? I tried the flush mode and tried again and it did the same thing. Any thoughts?

Check intake is clear.

Thank you. We did check the intake and it flows well.

What control system do you have on your NewPort400, the MPC controls or the new Connect controls. The MPC has the push button controls and the Connect has a touch screen control. What service did you have done to the system and was it calibrated once the work was complete?
