First follow the diagram in your service manual. Make sure the water pressure is off. The sensor is held in place by a few clips. Fairly easy to remove. Once the sensor is dis connected make sure it is clean. Often there is a calcium build up. A soak in something like vinegar will dissolve the build up. After soak rinse with water. The wheel should turn freely. If so lubercate using PAM spray. Place unit back together. Flush air out of the system and it should be good to go.

It is best to just replace it. You can try and soak it in vinegar if there is calcium build up on it. For more info you can contact tech support at 1-800-519-8794

Do as they say below, I try to flush mine out about once a year, google it and the process will come up, it is pretty straight forward and easy to do. You will need a pump to pump it though, I have had no issues with my unit I love it, we use it a lot also with 4 kids using it and taking baths ( 100 plus Gal tubs )

Other option is to remove the mass air flow sensor and spray the wire/sensor. Did it to my VW passat and wasn't too hard.

Well, in my humble opinion we (Jandy owners) have been taken to the cleaners on everything they sell salt-wise. Did you clean the cell with diluted acid? If so try that. Did you install the sensor with the new chip adaptor? If so, take off the adapter. It is a really bad fix. It seems to make all the bugs that everyone complains about worse by increasing, rather than decreasing, the sesitivity of the sensor. I got a few months (my non-heated season) out of my sensor (with one cleaning midway) by removing that jumper. I too am now getting a 121. I am going to clean the cell tomorrow, make sure the three prone plugs are clean, reboot the whole thing, and see what happens. If it doesn't fix, I am turning the whole thing off, saving my money, and buying something that works. Good luck.

It has a filter on the bottom, so just keep that clean and it should never lose CFM. You can wash it with water as it is plastic, just make sure it's dry when you reinstall.

This was surprisingly easy to do. Use a flat head screwdriver to carefully pry out the black gasket and screen. Set aside. Use a 1/4 inch drill bit and drill slowly into the flow restrictor below. When the drill bit punches through the plastic (60 seconds) pull and out will come the flow restrictor attached to the drill bit. Replace the gasket/screen and you are good to go. This took less than five minutes, and I am not a handy person.

If you are asking if the sensor itself can be cleaned, I don't think so. I recall the instructions recommend simply vacuuming the unit once a month but this is a pretty standard sealed unit, minimal maintenance sort of detector.

On the bottom of the black filter cylinder there is a tiny + and - button. Push on the - button with a skewer to decrease the flow. You have to pull the whole black filter out of the white case to do this.

I did reset mine but I probably didn't need to. I also covered the sensor with a piece of tape.

Sorry to hear about your trouble, try to run it on max without the ion function on for 15~20 min after you clean the filters. Good luck

Right below the red light is a recessed reset button for the light. Once you clean the filter stick a pencil or an object that can fit into the recessed button below the red light to reset the cleaning indicator. Took me an hour of fustration to figure that out >.<

Use the tip of a ballpoint pen in the hole next to the red light indicating clean the filter. Takes a few seconds and the red light goes off. I haven't had a problem with this. Janice

You have to remove the mass air flow sensor from the air cleaner housing. You still have to use the frame work the sensor mounts in and install it on the end of the tube coming from the throttle plate. The is not a happy camper without the mass airflow sensor.

My unit blinks if the filter needs cleaned but has never bleeped. You could try cleaning the filter, plugging and unplugging, and look into filter chamber to see if something is stuck in there. Otherwise, I don't know of a reset button.

Have you tried washing the sensor? Just use water, nothing else. My sensor got dirty and I had this problem. Cleaning off the sensor did the trick. And don't forget these are warranted for five years. When my motor died, they sent me a new motor with instructions how to change it out. Piece of cake.

It appears there is something wrong with the sensor! I will be contacting the manufacturer since it has a warranty.

I had to replace one a few years ago. I believe I reset it so many times that the reset failed to function properly. I read Hippie Bob's suggestion and wish I had tried that before I discarded the original sensor. Good luck .

One of the parts that comes with the system is the "Quick Connect Fitting with Filter and Cap." The screen inside may need to be cleaned per the instruction manual. Other filters that you may have installed may also be restricting flow.
