So, I have a doozy one here. I have a CWP 106 H that intermittently restarts on its own. Tech support recommended replacing the screen as we still had the original version. Screen was replaced last night along with cable and for the most part, it worked fine up until this evening. There is no alarm when this happens, it just restarts. Now, we have the CWP in water saver mode due to our city water that tends to drive the conductivity up in our area. So, it is not a conductivity issue. Even if it was, there would be an alarm for high conductivity. Has anybody encountered something like this? PLC maybe?? Currently waiting on Marcor Tech Support and have literally been on hold for 40 minutes as of when this was written.

Test your incoming power lines for fluctuating VAC. It should be fairly stable even during operation. If you have fluctuations then connections need to be tightened in the CWP and the power line leading to the unit. If you have these fluctuations in multiple places in the clinic (use the ESA its easiest to test outlets) then you have a neutral problem coming into the building. I have come across both situations for power issues. With no alarm that's about all that makes sense, that the CWP thinks that the power has been cycled off/on. I am curious so please post your find.

Thank you justabiomed. I will definitely look into that. As of right now, we ordered a new PLC just in case. It's been running normally for the past couple of days, but we are continuing to monitor the issue. I will let you know what comes out of it. Thank you for replying.

Just thinking, depending on where you are at in TX (maybe?), those stormes there could be running havoc with the power grid.

Yes to the PLC. Last year I had the same issue with one of my CWP's. Marcor suggested replacing the screen, which we did, only to have the same issues afterwards. Replacing the PLC is what fixed it for us. The old software version in the old PLC is the issue.

I had a contactor going bad that was doing that intermittently many years ago. Changed that out and fixed it fairly cheap (for MarCor). If you can swing the whole PLC, go for it!
As for the screen, we still have the old MAC controllers so changing that out is akin to saying "change everything but the pump and membranes"...lol
