The "clean metal grid" light is flashing red and i have already cleaned it very well and it still flashes. So, my question is: Does anyone know how to clean the metal grid properly or is it just a malfunction?

Usually there is a "reset" feature ont hese type of machines that you have to reset after cleaning filters etc. - often it is a combination of buttons.
Hope this helps :)

If none of the hi voltage grid wires have broken then check to be sure grid wires are truly cleaned. If not cleaned in a while like every 2 weeks they will have carbon build on them. And from my experiences with cleaning them is the build looks similar to the color of the wire. Try some qtips dipped in alcohol or cotton balls. The build comes off like flaking metal. Also be very tender with these wires they break fairly easy. When done cleaning turn upside down and back so beads can scrape up and down on wires. Also you do know once clean the parts especially the big collection bars they need to dry for at leased 24 hours before ever powering unit back on. Hope this helps.
You should clean the purification plate once a month. Using a 1 part water and 1 part amonia solution, dip an old toothbrush into the solution and scrub the metal grids on the plate to remove any dirt or deposits on the grids. Remember to do both sides of the plate. After the grids have been scrubbed, rinse with warm tap water and allow it to dry completely or use a hair dryer to speed up the drying time.
It would be a good idea to scrub the metal contacts that touch the plates inside the purifier as well. The plates should be changed if they develop a crack or there is noticeable arcing when the purifier is running. Hope this helps you.
make sure not to forget cleaning the corona wires. i used light grade sandpaper and gently cleaned the wires as well as scrubbed the metal grids with scotch brite pads. the unit has been running normally .
i have the same unit. clean the corona wires very gently with light grade sandpaper and scrub the metal grid blades thoroughly with a scotch brite pad. my unit was sparking like a lightening storm. after i cleaned it this way it runs perfectly.
the metal contactors and the wire spade connectors get pretty corroded and can cause continuity problems .i have had to replace those spade connectors and clean the metal contactors with emry sand cloth.another trick is to soak the plate in ammonia to reduce the corrosion present on the grids
I had the same problem: Had cleaned it inside, taking off both grids, washing wire, etc. Still the red light blinking would come back on after a few minutes. So here's what I did next:
Take off the grids on both sides. Make sure the grids are clean with water and paper towels (lots of black) On the unit itself, wipe out the metal sides and all the plastic. Then, here's the KEY,
get out your computer cleaning canned AIR and blow it into the open unit and blow the air on both of the grids too. I first used a hairdryer to blow it out, but the canned air is much stronger and I got all kinds of little black particles out with it.
Put it up and down 3 times, plugged it back in and WALAA! The unit is back to working perfectly and no red light has come on again!
I'm sure this will work for everyone if you just get the canned air and blow out the unit and the grids too even though you've cleaned them!
Sharper Image was giving customers a small rebate for the product since it was proven to be ineffective for cleaning the air by Consumer Reports as well data by the EPA.
This has caused a mess for Sharper Image that they went into bankruptcy as a result of it. The Consumer Products Safety Commission is going to be making a decision on ionizers at the end of year since there are hazards in the air from using the devices. It could be that ionizers are no longer sold in the US next year.
The industry should have been regulated and unfortunately the government never did anything about it until Sharper Image and Consumer Reports went to court on it.
Have you cleaned the bars lately? I believe that red light means that the bars that collect the junk from the air are at capacity and needed to be wiped down.
If you don't know how to do this, pull them out from the top after having turned the machine off. Get a rag or paper town moist, but not dripping and just wipe the black soot off all visible sides of the metal bars. Lay it aside when done over night for it to dry completely, then re-insert them into the machine. Turn on and hopefully that should take care of it!
I cleaned the filters as well earlier and the red filter light still blincked to clean the filters. Then I pushed the power button for about 10 seconds continously and then turned it on and the light turned off.
