The unit is completely clean and dry. When I turn the power on, the light goes immediately to red(clean). What's wrong?

Make sure filter is positioned correctly and fully seated.

If it does not come on with a clean dry filter it may be a faulty high voltage component.

Wiping it off won't clean the filter. I submerse mine in hot soapy water ( oxiclean w/any favorite multipurpose liquid cleaner.Let it air dry completely before placing it back in unit.I have tried the dishwasher method and it didn't clean it.I also thoroughly wash all crevices of the unit.If red light doesn't go off, reclean the filter(s). It has all ways worked for me.

When you cleaned everything did you also turn the whole unit upside down and gently shake to remove trapped dirt in the bottom of the unit. As for taking this unit apart to clean throughly there is no need. Just use some q-tips with 91% Isopropal alcohol not Rubbing alcohol to get to the small areas. Pay close attention to the small arrow shaped metal contact near the bottom of the unit. Make sure it is wiped clean and everything is completely dry. Plug unit back into power and the red button should turn green.

I have the same problem. If there is no reset switch I'd say it's trashed.

The Classic XL-15 should have 2 individual indicator lights. The 'red' light is the ionizer indicator, and the 'green' light is the ozone level indicator. Both lights should be illuminated, if the unit is operating properly. The red light should be pulsing, and the green light should be dimly lit, and brightened as the output knob is turned up - indicating a higher ozone production. If the green light is not lit, you likely won't smell the ozone. The first thing you should try, is cleaning the filter and glass ozone plate. Unplug the unit and remove the rear air filter. Clean the filter with clean water and allow to COMPLETELY air dry. Removed the glass plate by depressing the lever behind the glass plate, and gently pulling it out. Clean the glass with a half water, half ammonia (or distilled white vinegar, if ammonia not available) and an old toothbrush to clean between the mesh. Dry plate with a hair dryer and re-place plate into unit. Replace dried air filter, making sure the little tab on the bottom is secured into the interlock. Power the unit on and you should see the indicator lights and smell the fresh ozone!

slow blinking light means the unit is in DRY MODE.. flast blinking light means some sort of arcing or bad power supply..
if in dry mode let the unit run for an hour and it will stop blinking ..

If, when you push the on button it sizzles for a sec and then shuts off (red clean light goes on), I have the same problem and haven't been able to fix it. However, others have had the same problem and have posted their solutions. The sizzling sound is caused by electrical arching between the plates and one or both of the two tungsten wires that are run parallel to the plates (if you turn off all the lights and wait for your eyes to adjust to the dark before turning on the Ionic Breeze, it's a pretty cool light show!) Here are things found by others to cause the arching and what they did to fix the problem:

• --dirt, lint, or tiny hairs stuck somewhere (usually towards the top or bottom of the plates or wire, and maybe in the grid contact points). Clean it better. Using canned air can help blow out the problem.
• --water droplets. Make certain there is no moisture anywhere when you put the grid (plates) back in. Using canned air can help dry hard to reach areas.
• --burn marks or melted plastic. These indicates a short circuit. Says dnewcombe1: "There is a feeler bracket that guides the two rear thin wires while the cartridge is being inserted. This "feeler" can melt and become disarranged." You can't fix this issue.
• --build up on the ionizing wires. Clean them. It's hard. I took mine apart and used steel wool.

My ionic pro did the same, the red light just wouldnt go out, so I looked down the plate opening, (with unit unplugged), and could see one of the wires was broken. (these are the ones you clean by pulling up that plastic tab). I am currently looking for replacement wires, will post my progress. GregV

"A blinking light indicates when the blades should be wiped clean with a damp cloth." I actually had a "handyman" contract last year to visit an elderly gentleman once a month and clean all 9 of his Ionic Breeze GP air purifiers. Before I did that for him, they would make hissing noises and he really didn't like that. Here's how to clean the operative compnents of these machines: First, unplug the machine and place on a work surface, such as a table or kitchen counter. Second, remove the metal blade insert from the top by gripping the release tab and lifting it up and out. Also remove the front and back grilles by pressing on the plastic tab at the bottom and lifting up on them. Third, use a damp rag or paper towel to wipe the three metal blades clean. Do not immerse this assembly in water, because it has to be completely dry when re-installing it in the machine. Fourth, use a small piece of damp paper towel to VERY GENTLY wipe clean the two thin wires inside the unit. These are located behind the two rubbery flat blades just inside the unit and can be accessed from the front side. You won't damage these rubbery flat blades by pushing your hand gently between them, but be VERY CAREFUL when wiping the wires clean. (This step is important, as the wires must be clean.) Fifth, using another bit of damp paper towel, carefully clean the wire attached to the inside of the front grille. Dry this off with a dry bit of paper towel, then clean any accumulated dirt off the front & back grilles. Check the metal contact near the bottom of the front grille (attached to the wire) to verify that it's clean and will make good electrical contact. Sixth, pick the unit up and turn it upside-down & right-side up about 6 to 8 times. The two wires inside have plastic beads on them that slide up and down the wires. This brushes any bits of leftover dust or lint off of the wires. (Again, these wires must be VERY clean.) Seventh, replace the front and back plastic grilles by placing them in their slots and sliding them down to snap into place. Verify that the assembly with the three metal blades is COMPLETELY dry, using a hair dryer if necessary to dry off damp areas, then slide it back into place from the top of the machine. Now the cleaning process is done, so plug the unit in and turn it on to test operation. If it makes ANY noise, then some component is not completely cleaned off, or still has a presence of moisture, which must be completely dried off before the machine is ready for operation. Hope this helps! ;)
