I have an Aqua Rite unit - Code says AL-1 and software 1.4. I think it's probably 4 or so years old. My salt reading was around 2600 and I kept adding salt and eventually began getting algae in the pool. I went to the pool store and had the water tested and they showed a salt level of 5000. Thinking the cell probably needed to be replaced after that many years I ordered a new T-Cell 15 and replaced the old cell and the salt reading even with the new cell continues to be low.
I drained some of the water and put in fresh and according to a recheck at the pool store I got it down to 4000 now - but the Aqua Rite now shows only around 2000.
The unit comes on and says its generating for maybe a minute, but then stops and the check salt and check cell lights come on.
I tried recalibrating the cell per the instructions I read on this forum but since my instant salinity reading never goes above 2000 to 2100 level I cannot set it any higher than that. I reset it to 2000 thinking if the reading was low the unit would still think it was within limits and generate - but no luck. It continues to run for a minute and then the check salt and check cell lights come on.
I opened the box and inspected the boards and I could see no issues. No burned spots - at least from the front of the board - and no dirt, ant issues, etc.
I have ordered one of the water testers and hope to get that soon so that I can confirm the salt reading from the pool store. Having tested it twice, though, a week apart, I'm guessing their reading it fairly accurate.
Any ideas on why the salt reading is so low or how I go about resetting it? Do I have a problem with the main board? The cell is new - so I'm pretty sure that isn't the problem now.
Any help or ideas would be appreciated. Thanks.
