I received this unit yesterday and it worked great. Today it wont "see" there is water in it. Filled just below square but red light just flashes. ??

I had the same problem and finally returned it after trying for weeks. There must be a defect.

We have three in our office and they work great. Decided to purchase two more and they didn't work. Both with different issues. One worked one day and then would not work after that. The other one kept shutting off - overheating. We sent them back and haven't reordered. Sorry yours does not work. Return and get a replacement if you want to hopefully get one that works the next time. When they work they are great.

Make sure you're not using distilled/reverse-osmosis or high-alkaline water, the vapors won't come through if you do. If straight tap water yields the same results, return the defective unit.

Hi - we had a similar problem and contacted the company. They were extremly helpful and replaced the unit . A pain shipping it back but the replacement was quick and the second unit works perfectly .

When the unit is working the light is very faint, but it is also possible that the bulb has blown or the unit isn't working. I would try putting it in the tank, turn off all the lights, and then see if the light is on at all. If it isn't you could try returning the unit, contacting the company, or just buying a new bulb to see if it was just the bulb. I have been using this for a while without any problems. Also, you will only see the blue light in the little circle at the bottom in the front when the unit is plugged in and workign properly. Hope this helps a little! Good luck!

i had the same problem, the red light stayed on & couldn't get the green light to show until i adjusted the float knob (the white knob)...then it worked perfect!

Mine worked fine. If you don't see a light inside the unit when you plug it in, either the unit is defective or it not connected properly.

Water will flow through the unit until the sensor detects a leak. There is an audible alarm then as well as a flashing light. There is no water flow then.

Well, to begin with, my device did not work right from the beginning. It opened water fine but did not always close the valve. I had to return it.As for your case, did you replace a battery? Or maybe battery voltage is lower than normal. Clean the contacts maybe.

well i would try to fix it myself first by checking all the batteries, check for water in unit etc etc. if all else fails you should let amazon know about this problem see if they will exchange if not move on..

Mine had the same thing. I actually cleaned it out real good and ran straight water through it and now the issue is resolved. Not sure what it was though

Clean it out completely and check cords. Also make sure there is water in it, If not it may slow down or stop without it. Mine did that, but after I cleaned it and filled it back up, it was up and running. I think it's because the water was too low. That makes sense to me.

It would do that for me as well when there wasn't enough water in the reservoir or if the canister and top weren't totally locked onto the base. I also remember reading reviews where some of them had glitches that caused the lights to flash and it wouldn't turn on. I would contact the manufacturer!

I just bought this unit in December and I have the exact same problem. I love the unit. It is on my bedroom carpet so I am going to try to put a mat underneath it to see if that helps and I will try to change the water level a bit as another person suggested. My guess is that the water sensor works well and the system needs to be level. Someone else told me to put it up at the highest setting and that may help. I really don't want to have to replace it and its too late to return. It really is an awesome unit. Looks great too

Hi Melanie, Sounds like somethings wrong. I put mine in the water first, then turn it on, & it runs.

Yes, the level is red and should be visible when there is water in the unit. When the level gets down to the MIN mark it isn't as obvious but at that point, a signal goes off to let you know it is low.

The light started flashing in mine as well -- still worked though and I couldn't find where I put my manual. We completely emptied it out because we were going out of town for a week. When we returned it was working normally! Try emptying it and refilling, I read somewhere that the 'float' may not be working right, and thinks the machine is empty.

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.

It will flash empty where the water reservoir is half full. Fill it to the line and it should restart. If you are using oils - as opposed to hydrosol's then cleaning off the metal disc occasionally has made it work for us. As another said it is only recommended to use with water soluble oils - hydrosols
