I have a 300H alarming 204 insufficient water during a run. I’ve replaced both boards, optical sensor, pump, and needle valve. Anyone got any suggestions on what’s next. Contacted Marcor but feel like they just throw parts at it.
have you done a low ph clean on the membrane? we do monthly, now we're having to do twice a month. water just went super crappy, clogs the filters and the membranes, have to replace all the filters as frequently.
In addition to kendec's questions, what's the actual output of the ro?
