Stuck on 2200 Salinity

I have 3 year old Blue Works Model BLH60-A SWG. I moved my pool equipment to a covered warmer place this past summer so I did not close my pool this winter. I notice back in the fall the salinity read 2200 despite knowing it was higher - assumed it was due to colder water temp. Today officially tried to make sure the pool was ready for the summer - water temp 69 deg F. Measured salinity with electronic reader and it was over 3400.
I cleaned the SWG with muriatic acid water mixture for 30 min.

Afterwards it still reads 2200 -- I wouldn't worry about inaccurate reading but after running the pool and SWG for 12h or so I get a "SLO" error. I am prtty sure some chlorine is being generated but nowhere near normal amount.

Sugggestions for troubleshooting or fixing?

Thanks!!
 
Is your SWG panel powered when your pump is off?

This is the basic information we need to know in diagnosing a problem:

  • Report all diagnostic readings when you..
    • Move the switch from auto to off and check all of the readings.
    • Move the switch back to auto and recheck the readings.
    • Move the switch to off for a minute and then back to auto and recheck the readings.

The SWG is powered through the same 220 as the pump. Variable speed pump runs 24/7 but slower at certain times.
I have tried the on off auto switching
And leaving off for a minute or more
Tried full power off for a minute or so
 
You know you have 2 clocks and at least one of them is wrong. With the typical variance of the cell reading, your actual could be swinging while the cell reports the same number.

The handheld meters can be off by a similar wide range. Maybe at +/- 500 they are both reasonably right. Or at 2700 the cell is slightly more right that the out of calibration handheld.

You just don't know unless you know. I suggest you find out for real. :)

Nonetheless you should never dose from an electronic test for this exact reason. You need a drop kit either way.

Here are the readings for each scenario (in the order of cycling through them):
starting
0.71
28.3
-0.00
73P
0500
At - 5
r611
t - 15
E000
--EE

next
0.71
12.2
21.4
-3.73
-4.51
73P
2500
At - 5
r611
t - 15
E000
--EE

after off for 1 minute
0.73
18.2
-3.04
73P
3700
At - 5
r611
t - 15
E000
--EE
 
Your Blueworks is a Aquarite clone system.

The diagnostics are reporting salinity of 2500 on one polarity and 3700 on the other polarity.

The 2500 is indicative that your cell is depleted and needs replacement.

Do you know if there is a good source for ordering a replacement sale and hopefully Cross referencing a sale that will fit into my current plumbing and work with my electronics?

Nope. BlueWorks is not widely available and I have never needed to deal with them.

How did you end up with a BlueWorks SWG?
