I have an Aqua Rite t-cell-15 and control panel rev 1.4 that was installed in July 2008 when my pool was built. I have (or think I have) maintained the t-cell properly every season, removing and rinsing with a strong jet of water 3 or 4 times a season and I've never seen any deposits or buildup in the cell. When I opened my pool this past weekend, I gave the cell an acid bath (4 parts water, 1 part muriatic acid) for 10 mins as per Hayward instructions. Yesterday, I turned on the SWG for the first time after bringing the salt level in the pool up to 3200 (tested with Taylor salt water test) and last night the Aqua Rite control panel showed a salt level of 3200 before I shut the pumps off.
This morning when I checked the salt level on the Aqua Rite control panel about 15 mins after the pumps came on, the salt reading was 1600 and the check salt and inspect cell lights were on. I tested my water again with the Taylor salt water test kit and the salt level is 3200.
I don't have a diagnostics manual for my revision (1.4), the nearest diagnostic manual I can find is for rev1.5 which is from 2009 and there are some obvious differences so I'm not sure if the diagnostics in the Rev1.5 manual will apply to my equipment.
The readings on the control panel are (I know what some mean but not all):
Avg Salt: 1600
Chlorine %: 52P
Instant salt level: - 0
Compatibility setting: AL-0
Power light is on
Check Salt light is on
Inspect Cell light is on
Switch set to Auto
I realize it's 7 years old and maybe it's time to be replaced but if I don't have to, I'd rather not.
Does anyone have any suggestions on what I can do or try??
