How to remove the salt cell from the system

turn off pumping system and close flow valves (if present). turn off power to duoclear system. remove the cap from salt electrode (press on). if it is hard to remove, that is good. wiggle it a bit and it will come off. unscrew the retainer ring on electrode. the electrode is now ready to be removed. lift it straight out of the housing. sometimes, the trap door on housing will get stuck in the electrode. this is a real pain. do not force the unit out. you have to take a bent wire and while lifting the electrode out of housing, use the wire to push the door closed (toward the nature2). once this is done, the electrode should lift out easily.

I want to clean my electrode, but the electrode connector seems to be stuck. I don't want to pull too heard. Could there be a build up of minerals holding it on? What do I do>

there is a 'one way' door on this unit that sometimes gets stuck in the electrode when it doesnt close properly. there are two things you can try.
lift the electrode and using a bent wire, try to close the door (on intake side). if this doesnt work, try reversing the water flow from the pump to close the door.

Can't adjust the chlorine output level of Zodiac LM3-15

Nost often it just needs to be cleaned. Calcium build up can clean in a tub of 1 Part muratic acid to 5 parts warter. or a 2 to 1 soultion of vinigar and water, otherwise it could be faulty. Cleaning typically works.

When I turn the system on the return water is cloudy

This is typical for the first 3 days to a week (depending) on climate. the unit is designed to let the first solution as a sort of shock which tends to cloud the water. This will clear up and water will turn clear.

Three of the burners don't work.

Basically, the electrode that causes the spark to jump from it to the gas ring/top is shorting out because of the water. It has to be bone dry and clean for it to work. With the rings off, make sure they are dry and use say kitchen towel to clean and dry the electrodes. Be careful, the electrodes are fragile and will not take any punishment. If in doubt you could use a hairdryer to dry the electrodes but do not have it too hot - the force of air alone may be sufficient to clear away the dirt and damp.
Watch the spark on the one that does work to see what it should do!

I have the zodiac duoclear system and have used it for nearly two years. All in all, it's a very good system. I have had similiar issues on occassion. Have you tried the master reset button on the lower right hand face of the control board? I've been able to clear up the lights by resetting the system.

If the salt content in the pool is not correct, the system will not allow you to superchlorinate. Your salt level should be at 4000 ppm. The add salt light is programmed to come on if the system gets below 3600 ppm. When the system is below 4000 ppm, it is unable to generate the chlorine needed. The lower the salt, the less you can chlorinate. Might not be your problem, but I've run into this before too.

The lights for replacing your cartridge puzzle me. I'm making an assumption that your pool is probably dirty if you're trying to superchlorinate. The dirtier the water, the faster the electrode in the cartridge will get covered in scale from the current and conversion process. Try cleaning the new cartridge by placing it in a bucket with a 75% water and 25% muratic acid mix. Let it soak for a few minutes and gently swirl it around in the mixture. This will clean the contacts in the cartridge.

Keys with the Duoclear system: Salt content and clean the filters regularly. Don't know if this will solve your problem or not, but good luck.
