I have an AutoPilot Soft Touch Model #ST220, cell SC-36, 230 VAC. Unit is approx 4 years old.
Service light flashes twice constantly.
I have done the following:
1.) Checked the cable, banana plugs and salt level. Plugs looked slightly worn but appear to be snug. The contact pins on the cell appeared not to be corroded and were wiped clean.
2.) Neighbor, an electrician, checked the internal fuses - OK
3.) Calibrated the unit in the salt mode as per the instructions. Salt 3000 ppm.
4.) Checked the cell. It showed light scale build up which I cleaned. The blades do exhibit some wear but it is difficult to see them very well.
Diagnostic readings as of yesterday...
Volts = 2.5
Amps = 1.8
Unit produces purifier and maintains good FC level in pool.
With this scenario, does the flashing service light ultimately mean the cell is on the way out?
Any suggestions would be appreciated.
