We moved into a house last summer and I am in the process of getting the pool squared away and have everything humming except for the SWG. It is a Ecomatic ESC-36 that looks to have several years on it. It is from the Monarch days. Cable looks to be in good order.
Salt level is at 4700 based on salt strip and pool store readings. All the other levels in the pool look fine based on my test strips and taking water in to the local pool store. I've had to supplement with liquid chlorine due to the issue outlined below.
The issue is that, the SWG works at 100% if it is turned on at one polarity, when it switches polarity, it will reduce down to a number lesser than 100%, usually around 45%, then go one LED red, then two.
If I turn it off, switch the leads, turn it back on, it will go back up to 100% and begin producing chlorine.
If I do the opposite, have it run at 100%, turn off, switch leads, turn on, it will run at the 45% go one green then two at which point it is no longer generating chlorine.
I've taken the cell out, inspected it and cleaned it. It doesn't look new by any stretch but is free of scaling and erosion of the plates.
My questions to the experts is, does this seem indicative of a bad cell, or does it seem like something in the unit itself?
Any further analysis I can do to isolate the problem?
Thanks in advance.
