I hava a Polaris Autoclear Plus SWG. It is 6 years old and just replaced Salt Cell 30 days ago. It is now showing error code 91. I have been told there is a combination of buttons used to reset the unit. When I hold the test button it shows the salt level is 0000 but test strips show 3250ppm which is a perfect reading for my pool. Any help would be appreciated.
After trial and error i figured it out. Unplug power to unit, wait for all lights to go out. Then press and hold the "UP" and "PROGRAM" buttons while you plug unit back in. Continue holding while display shows 8888 and then will display program time to run. You should now be able to set water temp and adjust time to run. Test button will now display Salt Level.
