SOURCE: water not flowing out of pump

Have you primed the pump by bringing water down to the pump? It will not work if the supply line is not filled with water from the pool.

SOURCE: Low flow indicator light comes on chronically.

If you have excessive calcium in your pool the calcium will solidify on your titanium plates. Look for little bits of white scale (looks like paint chips) in the pool usually by the outflow. To fix, unplug the chlorinator, remove the inflow and outflow hoses from the chlorinator, also remove the flow meter (piece of pipe that has the wire attached to it. Look in at the titanium plates. If it has white calcium coating it, then flush with the hose till it all comes off, if it doesn't come off remove that piece of PVC and soak in vinegar (haven't had to do that but thats what the manual says). Manuall says to drain 25% of your pool and refill with fresh water but I elected to just keep cleaning it out when the alarm went off untill all the calcium in the water turned to solid (had to clean 3 or 4 times). Be sure and vacuum up the calcium in the pool.

SOURCE: Intex salt water chlorinator I added a higher flow

your pump has nothing to do with chlorine generation.
You need to get a salt test kit that reads in #'s not colors.
Now get your salt to 3000ppm or as close to it as you can.
The amount of salt reccomended in the manual is just a starting point
any lower than 2800 and you will not produce enough sanitizer and over 3600 and your pool can go cloudy, taste bad, and rust metal parts

No flow is red and no chlorine lights indicating chlorine

I assume you are describing a salt system.
Ensure all baskets are cleaned out, filter is clean and proper flow of water.
Check salt cell for calcium buildup.
Beyond that it could need a flow sensor replaced.

Zodiac LM2 Chlorinator. Super Chlorination light comes on, no other buttons work. Unplug and plug back in with same effect.

there is a 'secret' reset button located toward the bottom left of the control screen. if you run your finger around the zodiac symbol, you will find the indent where the button is located.
you will see all the lights go off and then light (or the other way around) as it resets.
make sure the leads are all connected.
if this doesnt work, or stays the same, remove the cell and inspect where the leads hook up to see if one has burnt off inside the cell. sometimes, you have to clean the cell to see it properly

Most low flow alarms are caused by the pump stopping before the chlorinator cycle ends. You must set the chlorinator hrs between the pump cycle. Start and set your pump cycle, wait at least15 to 30 minutes and then set you chlorinator hrs and make sure to it completes it's cycle at least 15 to 30 minutes before the pump cycle ends, If your pump turns off before the chlorinator cycle ends, you will get a low flow alarm......

Im getting a blinking 93 and my water wont clear up.

93 is stand by mode indication of the cycle completed.. You may need to increase the cycle time.. The manual is very conservative!!! I have a 14000 gallon pool and I run my intex salt system during the summer at 10 to 12 hrs pump and 8 to 10 hrs chlorination in between those 12 hrs and my pool stays very clear. But..... If you don't clean the unit and let it alarm for low flow, low salt or not run the unit log enough, you WILL HAVE GREEN WATER!!!
Hope this helps, If it does, please rate the tip!

Intex Chlorinator Problem: After holding down left arrow and it beeps, i set hours on timer and then it blinks with that number for about 2 minutes and goes to CODE 94=not operating.

First make sure the pump is running and water is flowing through the clorinator. (wont work if water isnt flowing). Make sure water is going in the right direction. (into chlorinator on the right side from the pump, and out of the chlorinator on the left side). The timer controls can be touchy.Try increasing the hours by holding the up arrow until the time is one hour more than you want, then use the down arrow to get it back to the time you want. Sometimes it wont cooperate with increasing the time and just stays at 1 hour, so you have to keep trying a few times.

Thank you for posting your question here on

Have you checked your water for acid levels to ensure you have enough to maintain your chlorine level? Adding stabilizer (cyanuric acid) helps the chlorine remain in the water longer and if you had to replace much of the water since your chlorine levels were OK you need to add more stabilizer to keep the chlorine in the pool. Have you altered the amount of time the pump runs too? An erosion feeder like yours only adds chlorine when the filter system is running. If you have scaled back the amount of time the equipments runs you will also be adding less chlorine over time than you previously had.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

I have a Pentair 320 automatic chlorine feeder. I have filled it with chlorine tabs, but I am still getting a zero reading for chlorine when I test my pool water. Can it be plugged?

It can be but probably isn't. A three inch tab is meant only to maintain your chlorine level. You must first bring the chlorine level up to specs, by adding either liquid or powdered chlorine, than add one or two tabs a week to hold it at that level.
