A cloudy saltwater pool usually means something is out of balance, under-filtered, or under-chlorinated. The salt system may be working, but it cannot fix every water problem by itself.
The mistake most pool owners make is treating the symptom first. With a saltwater pool, the better move is to check the system in order: water balance, flow, filtration, salt level, and then the salt cell.
A salt chlorine generator can only work with the water it is given. If pH, alkalinity, stabilizer, or calcium hardness are out of range, the pool can drift even when the control panel says the cell is producing chlorine.
Use Pool Chemical Calculator to calculate pH, chlorine, alkalinity, stabilizer, and calcium adjustments without guessing.

Make one change at a time, circulate the water, and retest. Saltwater pools are steady when the chemistry is steady, but they become frustrating when several small issues stack up.
Yes. Poor filtration, low stabilizer, high pH, or heavy swimmer load can cause cloudy water even when the salt cell works.
Shock can help if chlorine is low or combined chlorine is high, but test first so you know what you are treating.
Many cloudy pools need continuous circulation until clarity improves, then normal runtime can resume.
Low salt can reduce chlorine production, but cloudy water is usually a water balance or filtration issue.
