Pool salt cell not generating chlorine? Dit is wie je moet bellen

A salt chlorine generator that stops producing chlorine lets sanitizer levels drop, turning the pool cloudy or green within days. The most common cause is calcium scale buildup on the cell plates, but a worn-out cell, low salt concentration, or a faulty control board can also be responsible. A pool technician inspects and acid-washes the cell, tests salt levels and water balance, checks the control board for error codes, and replaces the cell if it has exceeded its lifespan.
