There can be a couple of reasons for this issue. First, have you had your water tested lately? In the manual, there are specific levels of chemicals that need to be watched so the unit will work more effiecently. Another item is have you cleaned the unit lately? If not, try to clean it. First with the garden hose on high pressure, if you have tried this, then it is time for a chemical bath.

To do one of these, you will need muriatic acid, water, two buckets, and a freezer bag and rubber band- if you do not have the chemical cleaning accessory kit. You will need to mix the acid and water in a 1 to 4 part mixture, 4 parts water to 1 part acid, in one of the buckets. Then turn off the pool system, if you have the check valve in front of the IC, close that also. Then remove the unit from the piping, on one end you will see a metal piece-looks like a flap hanging down- this is the flow meter for the unit. On the end with this, take the freezer bag and lay it across the opening, put the rubber band around the bag, this will make the cleaning MUCH easier. Once that end is sealed, place the unit, with the sealed side DOWN into the other bucket. Then pour the acid mix into the cyclinder, make sure to cover all the inside of the unit. You can wait five minutes, or until the bubbling stops, before pouring the mixture out of the cell. Rinse the unit with the garden hose and reconnect it. See if this helps, but I would DEFINATELY have the water levels checked first.

If you can give more details, like are there any lights on, or off, on the unit? How long have you had the unit will help also.

Our system continues to give a 90 code reading even though we have a big enough filter pump to push enough water through the system. Everything is tight and the system is clean. how do we correct this...

Code 90 indicates that the water flow rate is not high enough for the system to operate properly. This is measured by a white plastic piece hinged from the top of the pipe. As water flows by the plastic piece gets pushed back and up against the top of the pipe so that it touches a sensor. A couple of solutions are as follows or a combination of these:
1) make sure that all pipes and filters are clean and clear. Leaves or other stuff will slow the water flow.
2) check that the clorinator is clear of any blockage or dirt.
3) unscrew the flow meter and pull out to check that the hinge is clean and the plastic piece moves freely.
4) when you put the flow meter back in place try turning it ever so slightly which might make a difference. This has worked sometimes for me.
5) make sure that the clorinator is level. I tilted my unit so that the inlet side is slightly higher than the outlet as an experiment and this works as well since I was trying to get the flow valve to travel less distance.(it's a geometry issue)
6) make sure there is no air stuck in the lines. Try lifting the pipes/tubes to move air out and make sure you bleed your pump to ensure that it is full of water and there is no air trapped here that would reduce flow.
7) try taking any nozzle off the hose going into the pool. These may slow the flow coming into the pool and cause back pressure in the pipes.
8) I have a solar panel with a bypass valve. The clorinator only works when I run the water using the bypass valve so that no water runs through the solar panel. Try running all water only through clorinator with no other devices in line to slow the flow or produce any restrictions.
9) Try running the clorinator but take out the pump filter as an experiment. The filter may need replacing. Taking the filter out should tell you if this is the case if the clorinator works without the filter in place.
10) As a last resort check the flow rate requirements for the clorinator and on the pump you have. The pump may be undersized.

Too much salt in pool (4,100)

the leslies employe is right the only way to get rid of the high salt level is to drain the water i would say drain a 3rd and fill pool and check salt level some salt genarators can not make chlorine at high salt levels or when the water is cold
