Just replaced with new filters and red light is still on....
66632
Not having one in front of me, I would wager that the red light, which is supposed to remind you to replace filters periodically, will stay on for a given length of time and then turn off. It does not read as though it has a pressure or air flow sensor in the unit, so I do not believe its red light comes on except for a brief time every six months of operation or perhaps three or twelve months. You may be able to turn it off manually, which procedure may be told in the owners manual or you may be able to unplug the unit and, upon plugging it in again, it may reset itself. There is nothing to worry you overmuch because the unit is still operating and ridding your room of particulates as designed.

Yes, there IS an indicator for filter life...it's on the top of the unit between the faucet and the filter. BUT....it's not electronic, so there is no "light," per se. It's a mechanical indicator, under a lens, that moves slowly as water passes over it; when enough water has run through the filter, the indicator starts to show red, and when it's completely red, it's time to change the filter. The problem is that it's not electronic, which means that it has no actual light itself, but rather depends on reflection from light outside the filter. I found that while I could sometimes see it at night with the light over the sink turned on, it was much more reliably visible by shining a flashlight down into the little port.

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 &gt;.&lt;

I did not know there was a light. Suggestion: write the installation date on the filter canister.

I had the same problem with the red light a couple times. I ignored it and used the filter anyway :)

With the filter removed, look down into the cup that holds the filter and find the 2 contact posts that are right above and back a little from the light display. Check for dirt or anything that might interrupt the contact with the filter. Also check the bottom of the filter itself.

Usually the light goes out because the battery is dead. I took the battery out because it got to blinking red. Problem solved! I've never changed filters 3&4 as often as Watts says but if you use a lot of water you might have to. We have had RO filters, mostly Watts, for over 30 years and change filters based on water taste. You will know when.

I have the same situation, but after a much longer period of use. My second filter was at the stage when the light would flash red. Before I replaced it, the light stopped working. I replaced the filter, and still no light working. Checking online, I found that, with the filter out, you can access the switch for the light. I pressed it and the light activated. Put the filter back in and it didn't work. Repeated a couple more time, with no success. I also read online that there is no direct relationship between the light and the filter itself; it simply tracks water flow. I have decided to keep using it until there is an obvious change in either flow rate or water quality. I have the same situation, but after a much longer period of use.

My first assumption is in the filter wiring, or construction. This is assuming you are not using any other cables. If you are, first try changing the cable, and see if it helps. If not, contact Amazon about replacement.

Throw it. When you can't find it, it's fixed. No actually, I have never had one last long enough to deplete that tiny integrated battery which can't be replaced anyway. I guess just replace the filter every couple months and press on without the light...

The valve has been in the open position long enough for sufficient filtered water to have flowed to suggest changing the filters (probably not the RO membrane, just the other three). Just pull the battery and put it back to reset.

The pitcher can't "tell" when the filter is getting old. It's just a sensor in the lid that senses how many times it's been removed, etc. So it 'guesses' when its time to replace the filter. Holding down the button resets that counter to zero so do it when you put a new, fresh filter in and the light will give you an estimate on when to change the filter. I tend to use the filter at least a month after the light goes red.

After using mine for about a month I also noticed the same thing and had this same question. It was like that right out of the box. After researching the manufacturers website about this product it became clear that the red light means a burnt out UV bulb. The bulb cost as much as the whole filter and was not available so I trashed the whole filter. This is clearly not a quality product. Check www.aa-aquarium.com and see what you can find out.

I have owned and Alen 350 for about 5 years, and changed the filter about every 6 months. The indicator light does advance to red at about that time. I now own a new one, and the light seems to be progressing at about the same speed. I run the unit 24.7.

No, but the light on our filter doesn't work anymore period. Not green. Not red. Nothing. I just try to change it when I remember to do so or when the water starts the taste differently.

If the light is turning red check the sensor. If ita not turning on at all, it could be a circuit issue.

of course filters need to be replaced. try reading the description of item before asking such rediculous questions.
