Hi just checked my system and it is reading for panel "cell off service 1.r.-then when I push salt button it reads "cell off wait clean 1H7 or 5 " my manual says see 6.5 step 2. This is under electrolytic cell cleaning but step 2 is unplug yellow connector. Can anybody tell me if I just need to clean the cells? Last month I replaced the tri-sensor. Not sure if related or not. Thanks.
