Remove the plaques and using an old tooth brush clean with mild soap and water.. Rinse thoroughly, towel dry and finish drying them with blow drier. The interior of the unit and it's filter should also be cleaned. Depending on what type filer it uses (Aluminum mesh or soft mesh plastic) they too and can be washed with mild soap and water, rinsed and thoroughly dried. Any other type filter material may need to be replaced. Clean the interior with canned compressed air with a straw nozzle and a dry paper towel.
Of course, before you do any of the above, unplug the unit.
Just had the "snapping" problem over the last 5 weeks. First try was to wash the cells in the normal fashion. when the snapping started again in a week I washed the cells in the dishwasher. They began snapping again in a week or less so I removed the cells and made a very close inspection of them. Using a very bright light I noticed the wires had a very uniform coating of something light gray in color. I picked at that coating with my finger nails and it came off to reveal the BARE wire underneath, Ah Ha, that coating was NOT supposed to be there ALL the time. So, CAREFULLY using my fingernails and a bit of wooden stick I scratched off that coating on all of the wires (it goes all round the wire) to reveal the bare wire and now it works with out snapping. Those wires can be broken if you are not careful. They can be replaced but that's just more hassle than being careful.
Good Luck, be careful, it can be done by the homeowner (and should be done too).
*Plug in air cleaner and press POWER button until short “beep” sounds. . Press the RESET FILTER button by gently inserting a paperclip into the RESET FILTER hole on the control panel. The light will flash 5 times before a “beep” sounds to indicate the filter has been reset.
Pull off the front panel and look at the upper right, you will see two holes. One on top is the size of a pencil, and one below it the size of a dime. Use a paperclip, pen tip, ect and push the reset button in the center of the dime sized hole.

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.
My unit would display e001 and e003 errors. Cleaning the filter and replacing the ceramic ozone plate did not fix it. Ended up taking the board out and inspecting it. Three capacitors were bad. After replacing, the system is working again.
