Did you clean the plate contacts with alcohol? How old is the plate? Is the glue that holds the grid in place turning brown? If it is, it may need to be replaced. Call (336) 499-2505 and ask for free email supplemental cleaning instructions before you do anything else. The instructions may help you solve the problem.

CLEANING PREFILTER(S), CELL(S) AND POSTFILTER(S) CAUTION Sharp edges. Can cause personal injury. Carefully handle cell(s) or wear protective gloves to avoid cuts from sharp metal edges. Setting a regular cleaning schedule To ensure optimum performance from the air cleaner, the prefilter(s) and cell(s) must be cleaned regularly- twice a year with normal use or more frequently with heavy use. Use the wash reminder schedule below to help establish and maintain a regular cleaning schedule. Mount the wash reminder schedule in a convenient location. NOTE: You may let the heating or air conditioning system operate normally while the cell(s) are being washed. Simply turn off the air cleaner switch. Cleaning your Prefilter 1. The quickest and easiest way to clean your prefilter is to use the brush attachment of your vacuum cleaner to vacuum the lint off the dirty side of the prefilter. Greasy dirt may require soaking the prefilter in a tub or rinsing with the garden hose. Do not wash the prefilter in the dishwasher or car wash 2. The prefilter should be cleaned every 6 months or more frequently with heavy use. This will keep the prefilter clean of air choking lint that can make your system work harder. Vacuum the prefilter with a brush attachment, rinse it with a hose, or soak it in a tub. Do not wash the prefilter(s) in the dishwasher or car wash. Cleaning your Cells 1. A quick cleaning of the cells can be done by simply wiping down the ionizer wires with a damp cloth. This will help boost the efficiency of the air cleaner between full cleaning cycles. Ths quick clean can be done every time the prefilters are cleaned. 2. A full cleaning of the cells will return the air cleaner to its peak efficiency. An easy way to wash the cells is in a tub of hot, soapy water. Just soak the cells until the water cools, agitate and rinse. For details on cleaning cells, see below for Washing the cell(s) in a tub or Washing the cell(s) in your automatic dishwasher. 3. Because the efficiency of the air cleaner remains high even as it loads up with dirt, a full cleaning of the cells can be put off for yearly maintenance and a quick cleaning can be done more often. Those wishing to renew to peak efficiency or with heavier use may want to wash more frequently. Replacing your Postfilter 1. The postfilter is an optional filter that boosts the efficiency of the air cleaner. Do not wash the postfilter because that will neutralize the factory applied charge. 2. The postfilter should be replaced every six months to ensure peak performance.

Try unplugging it for 1/2 an hour and it may reset itself.

Yes. You will have a prefilter and after that you will have a HEPA filter. Keep good maintenance on the prefilters which are not washable. You will need to check it once a month to see if it is time to replace. If you have good maintenance on the unit and change the cheaper prefilter, you will get years of service out of you HEPA filter. Bad maintenance means replacing the HEPA filter which is a good chunk of the cost of the purifier.

I've had a problem with the contacts being broken. there are little contacts on the bottom of the plates that spring out when it is reinstalled. they push against 2 wires inside teh unit. make sure they have good contact...

Hi There,

Here's how you can clean the machine, and I have copied the link to the owners manual below for your convenience.

Cleaning
The Cabinet
You can clean the air purifier cabinet with mild, non-abrasive cleanser and a
soft cloth. IMPORTANT: Unplug the unit from its electrical power source.
Do not spray cleansers or furniture polish into the louver or grill areas.

Collector Cell
Indicator light is green under normal operation and flashes red
when the cell requires cleaning. To clean, proceed as follows:
The red "WASH CELL" light will flash or illuminate when it is
time to clean your cell. However, it is recommended that every four to
eight weeks or if snapping sounds become frequent, clean your
electronic air purifier. Your electronic air purifier is still filtering the air
when the red light illuminates. Cleaning your electronic air purifier is a
snap too... and a must for efficient operation.
1. Turn the unit off and unplug it from the electric power source. If wall
mounted, remove unit from wall.
2. Remove front grill by unscrewing the retainer screw under the grill on
the cabinet bottom. (fig. 1)

3. Pull the cell out of the cabinet by using the two small handles on the
front of the cell. (fig. 2)

4. Snap off the charcoal odor absorber from the back of the cell. Change
as necessary for continued odor removal. (fig. 3)
5. Slide off pre-filter. This can be cleaned with the cell and reused. (fig. 4)
NOTE: Handle the electronic cell with care. Damaged metal plates
and/or broken wires will cause the air purifier to malfunction. (Do
not wash charcoal odor absorber; it is disposable.)
Cleaning with Assail-A-Cell® Cell Cleaner:
6. Using Assail-A-Cell® Cleaner, thoroughly saturate the cell and prefilter.
Be sure to spray between each cell plate and cover every
surface. Allow product to soak for a few minutes, not allowing it to dry.
Rinse thoroughly with water. For extremely heavy deposits, repeat the
process.
IMPORTANT: Dry the collection cell thoroughly outside of the
air purifier before reinstalling it into the air purifier. Ensure
that all areas including corners and areas that may trap
water are dry before reinstalling into the air purifier. DO NOT
place a wet or damp collection cell in the air purifier

I hope this was helpful to you. If this helped, please be kind and rate the repair, or leave feedback for me. Thank you,

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 it says "Clean Cell Now" and it is a new machine, it is broken. I have six, yes six, of this model. They are all new and you shouldn't have to clean the filter/cells for a few months.

The way to clean is:

1. Unplug
2. remove the white cover
3. remove the prefilter. Good time to clean the prefilter by removing the 2 retention clips and gently swing the prefilter outward. Clean or groom it with a vacuum. Use the upholstery brush. wash the prefilter in warm, soapy water. No Chlorine! Rinse clean with regular water. Wipe with a paper towel and let dry completely. It is okay to gently use a hair blower to speed up the drying process.
4. Onto the Cell.
5. The cell can be washed one of two ways. Either in a hot tub of water or in a dishwasher.
6. Wear gloves to protect your hands. Never touch the fins or wires. It will ruin them and cut you up. Use the two handles.
7. Use hot water and dish detergent.
8. No chlorine and no abrasives.
9. Soak for 10 minutes, then dip a couple of times to remove stuck dust/dirt/schmutz.
10. Rinse with clean water.
11. Allow to dry
12. Allow to dry
13. Allow to dry
14. Okay to use a hair dryer to speed up process.
15. Reinstall
16. Power up
17. Press and hold CHECK button for 3 secs to reset.

Thanks.
