It is not your sensor

Most likely you either have air in the system or a blockage

A blockage can occur at the front of the motor from skimming or direct suction
you would be surprised what sneaks through the pre filter screens
Undo the hose in front of the motor first
there is a plastic housing screen that usually gets clogged

If it is air drain the hoses and the filter cartridge housing
now blast out your cartridge with a strong garden hose
Put it all back together
now open all bleeders except the one on the bottom of the cartridge housing
open dishcharge hose side first
when water starts coming out of the bleeders then open the inlet hose

Turn on pump for 30 seconds and then close the bleeders this should do it

Started my salt water system soon after adding a bag of salt. Now I'm getting a low flow warning even though there is plenty of flow. What could the problem be.

You may think you have good flow, but the sensor that always is confirming the proper amount of flow is telling you that it is not!

Especially if you have a Toy system. The filters that come with these systems are way too small and will clog quickly and provide a restriction of water flow.

Test naked Try this (after waiting 24 hrs and if problem still persists) take the filter out of filter housing and see what happens? Does the error go away? If so, then replace with "New" filter, not a cleaned one. Filter elements get clogged, with metals & minerals, that you can't see with a naked eye. It may look clean, but is not.

If all this is still creating a problem (with no filter element in place) then you may have a faulty flow sensor?? But I would not go there immediately because the sensor is probably just doing its job.

The first thing I would do is clean everything out as much as possible. Clean the filter and any screens to make sure they pass water well. I am told that the flow sensor comes apart and can be inspected, cleaned and if bent may be able to be straightened. I hope this helps.

Low water flow code

Most causes for this code is that the pump stopped before the chlorinator cycle ended. If not, you may have a dirty filter, low water in pool that caused no flow to the unit or stuck flow sensor... Make sure that you sync your chlorinator between you pump cycle...

System is completely clean (all areas) and it still beeps low flow when we try to get it to clorinate. Is the sensor gone?

If you have checked intake and outake valves at pool end for clogs and opened all the way, cleaned skimmer if using one. checked for blocked air in the system, made sure pump filter is clean, confirmed water is going into the salt generator on right side, and out on the left side, checked that the flow sensor isnt loose, checked that the flow sensor hinge/flap moves freely and is clean, checked that the filter on the right side of the salt generator is clean (most common cause of this problem), and that the electrolytic plates are clear, and if the alarm comes back on after turning off the unit then turning it back on after checking all the above then the sensor probably is bad and you would have to contact Intex Service Center for a new one.

It says low flow, how can i fix it. its a Intex Automatic Salt Water System for Above Ground Saltwater Pool

After five years of using our pool each summer, we assembled it last week and I kept getting the "low flow" warning (with irritating beeping) even though the water flow was very good. I disassembled the unit and checked the flow switch, and found that the switch itself was the culprit. Here's what I did: (this is probably not recommended by Intex...) I unscrewed the main portion of the salt water purifier (the part with the digital display on top) from the base and lifted it up to expose the circuit board and wiring. All the fuses were intact and everything looked good. At the bottom of the circuit board, about an inch from the right edge is where I found the connections for the flow sensor. One was marked "flow" and the other was "grnd". I removed the plugs that run to the slow switch, closed the circuit by making a direct connection between the two plugs, and voila! No problem. I ended up cutting the wires about 1-1/2 inch from the plugs and connecting them with a wire nut, then I plugged them back in. The unit is working perfectly again.

If you attempt this, make sure the unit is unplugged and be careful when dealing with the circuit board. Don't be intimidated, it's not a high-voltage connection you are working with, you are simply closing the circuit and telling the board that the switch is closed as it would be with adequate water flow. I was comfortable making this "modification" and bypassing the flow sensor because we have several years of experience with our pool and because I clean and swap out our pump filter every day during summer, and because we know the difference between strong and weak flow just by checking the inlet and outlet ports in the pool.

I hope this helps someone! It took care of my problem. Best of luck.

What can i do to get the salt water to reading

start by unscrewing the ring around your sensor and remove it. Although most likely not the problem proceed with blasting it out and making sure it moves freely

Re install

now drain all hoses and blast out your filter cartridge
now disconect the hose going to your PUMP check for debris and hair build up in the plastic filter housing

now put everything back together
open the top bleeder screw on the cartridge cap top and the one on the motor if your model has one

now open outlet hose first when water starts coming out the bleeders open the intake hose

now turn pump on for 30 seconds and close the bleeders

this should do it
if not intex will replace pump/filter or your 8110 before 2 years if you have a valid receipt.
Just call them and you will fax them the info they want usually your replacement will arrive in just a few days

hope this helps

Brand new system... Code 90... Checked for air in hoses & loose hoses, changed pump filter, everything installed correctly... Help????

Make sure your flow sensor moves freely. Soak the unit in vinegar if it looks dirty
I would also try bleeding the system run your pump with the bleeder screw on top of the filter cartridge open a few turns Just enough to allow the water and air to flow do this for a minute or so and then tighten the screw

If your pool has the skimmer system there is a hose coming from the bottom of the skimmer to the wall of the pool which would be your suction to the pump. Disconnect the hose clamp from the suction port that goes through the wall of the pool remove the hose then unscrew the blue adapter on the inside of the pool there you will find a strainer / screen. Whatever gets pass the basket in the skimmer get's plugged up in that screen causing the pump to starve for water causing the LOW FLOW sensor to go off on the Saltwater pump.

Let me know if this helps any.
