    AquaPure 1400 Code 120 &121 Help

    I just got these two error codes a few days ago (120 & 121). I tested my cell and flow sensor and i got some weird data. My cell voltage read 14v. It reads the same from where the cord connects to the board. But when i test port 4&5 it reads 0. Ive cleaned the flow censor and the cell also. My question is, wouldn't i get a different code if I had a bad board? i have the old 2 port cell. Im contemplating if I should just by a whole new system if i have to replace the cell. I had the unit for 4 years. What do you think?

    Welcome to TFP.

    I've seen those codes in a thread before. You might want to use the search box at the very bottom of the page to search for those and see what the outcome was.

    I found this troubleshooting document online a couple of years ago. It reports that:

    120-Low cell current in forward direction -check DC cord, clean cell if necessary or replace cell.
    121-Low cell current in reverse direction, same as 120 above.
