Aqua Rite Display only shows Salt reading.....Help

[JEC_PA]

Hi everyone!

Been searching for a while and with no luck, I've even called the folks at Aqua Rite without much success.

Here is my problem.

The display only shows the salt reading I can't get it to change. Tried re seating the display board, I've replaced the mother board. The display is nice and bright just wont budge when I hit the diagonostic button.
I've tried holding it....Holding it and cycling the auto/off button...nothing

Tried to recalibrate....no luck.

Has anyone else had this issue?.....Is the Next step is to replace the Display board?

Can you tell if the membrane button is actually working?

Don't know how to tell if it's actually working....I know it does depress and is not stuck.

Is there a way of telling if it's not?

Usually if it "clicks" for lack of a better term, when you press it it's working.

Well after taking another look I found 3 screws holding the display and membrane button to the PCB...I took the 3 screws off and discovered a greasy film on the PCB.....after a nice cleaning I put her all together and BINGO !!!

All working again !!!

Thank you for all the help and a 100.00 savings !!!
