Water maker in (not so ) troubled water

Hello wise sea men,
My water maker, ( brand AQUABASE for that maters) ran fine in sea water the last time I used it . I then rinsed it properly with its own made fresh water.
I am now trying to use it in the fresh water of Rio Dulce, Guatemama.
It starts fine, turn on its green light showing that the water produced is salt free , i.e. its resistivity is high, and sent to the fresh watertank by the 3 way valve. Then within 5 or 10 seconds, it switches the green light off as if it had detected salt (low resistivity)in the fresh water produced and turns the 3 way valve to throw the water produced back in the Rio.
Yet salt cannot come from the Rio which is not salty
In addition, I compared the water in my tank made previously and the water made now: Same absence of taste and same resistance around 30 KOhm measured with an ohmmeter .

Could this be caused by the use of the water maker in the Rio's fresh waterinstead of sea water ?

I am thirsty for advice

Membranes have maximum flow limits as well as pressure limits.

If you're running the membrane at seawater pressures in fresh water you could damage it from excessive flow.

ie in seawater ~ 800 psi is normal, in fresh it could be closer to 100, to get the maximum allowable permeate flow.
