No flow error on LCD screen

[mtesh73]

Hello everyone. I just noticed the "no flow" message on the LCD screen. I just cleaned the sensor with a scotch brite pad, just cleaned the cell with water and muriatic acid. I hit the reset on the daughterboard and am still getting the message. I also have a add salt message. The computer reading is 2.6, the Taylor test kit reading is 3000. Any suggestions as where to go from or I am destined to start replacing parts?

Also the water temp is reading in 100s at the SWCG LCD screen. I hit reset buttons for HTEMP and RTEMP as well.

My FC is also dropping it is 4, I will add some bleach.

ETA: recalibrated system to 3.0

@JamesW thoughts?

Disconnect the flow salinity temp sensor from the front board. Press and hold the test buttons marked salinity and R-temp. While still pressing the test buttons press the ‘Salinity’ key (‘C’) on the front cover of the unit. The LCD should read 2.8 gpl*.
While still holding the two front board test buttons press the ‘Pool Temperature’ key (‘D’). It should read 75° F or 24° C.
Next, press and hold the board ‘H-Temp’ test button, and at the same time press the ‘Salinity’ key (‘C’) together with the ‘Chlorine Production Rate’ arrow down key (‘A’) on the front cover of the unit. The LCD should read 91° F or 33° C .
If the readings are correct then the front board is O.K. and the problem is with the flow sensor.
On the other hand if the readings are different then it indicates that there is a problem with the front board.
When the testing and repair is complete reconnect the flow sensor and reset the internal computer (do this by restarting the unit).

How old is the system, cell and trisensor?
What is the number on the CPU of the circuit board?
Does the little daughter board have the jumper?

Turned out to be the sensor. Got one from Amazon. Newer design, easy install. Up and running with no issues.
