Troubleshooting; Common Problems And Solutions; Possible Causes Of Little Or No Free Chlorine Residual; Leds Not On - Hayward Salt & Swim® 3C Owner's Manual

and troubleshooting your Salt & Swim 3C Electronic Chlorine Generator.

Common Problems and Solutions

The Salt & Swim 3C's various LEDs show the operation status as well as alert the user to any
problems that may have occurred. Some indications may require a combination of LEDs to il-
luminate. To aid in interpreting these indications, Hayward has created an interactive tool located
at www.hayward.com. Use this tool and the information below to identify and correct problems
that may arise.
1.

Possible causes of little or no free chlorine residual

- DAILY CHLORINE OUTPUT adjustment setting is too low
- Low stabilizer (Cyanuric Acid)
- Filter pump time too short (8 hours for average size pools, more for large pools)
- Salt level too low (below 2400 ppm)
- Salt level too high
- Very warm pools increase chlorine demand--increase Output %, or filter run time
- Cold water below 50ºF causes Salt & Swim 3C to stop generating
- Cold water between 50ºF - 60ºF causes Salt & Swim 3C to reduce output regardless of
DAILY CHLORINE OUTPUT setting
- Excessive scaling on Cell.
- High level of Nitrogen in pool water.
- "Yellow Out" or similar treatment recently used. Some yellow algae treatments will use
chlorine at a very high rate and deplete the residual free chlorine. Manually shock the pool
if indicated in the directions on the algae treatment. It still may be a matter of days before
the pool returns to "normal" and chlorine tests will show the desired 1-3ppm free chlorine
reading.
2.

LEDs not on

Depending on current conditions, there should always be at least one LED illuminated when the
Salt & Swim 3C is powered. If no LEDs are on, check to make sure that the linecord is plugged
in and that the GFCI outlet is powered. If no power is detected, the GFCI may have to be reset.
3. STANDING BY LED blinking
The Salt & Swim 3C has shut down because the temperature of the pool/spa water is too high
(120ºF) or too low (50ºF). The system will not resume operation until the water temperature
returns to normal. Note: This condition can sometimes happen if the pool/spa temperature is
already high and the heater is running. The temperature coming out of the heater and into the
Cell could possibly be high enough to shut down the Salt & Swim 3C.
4. INADEQUATE WATER FLOW LED illuminated
Salt & Swim 3C has sensed a low flow or no flow condition and has stopped generating chlorine.
- Verify that the filter pump is running and there are no obstructions or restrictions in the pool
plumbing.
- Backwash the pool filter.
- Increase the speed of your variable speed pump
