Shark NV22L... | Answered on May 16, 2019

The disassembly is simple. Remove the four screws you noted at the top of the unit. Each side panel will then slide up about a half inch. Pull outward and they're off. (The bottom is held on by tabs on the unit and slots on the panels). Clean it with a combination of vacuum and compressed air. Wipe the blades down with a mild cleaning detergent. (Spray it on the rag and not on the unit to keep the electronics safe). When re-assembling, be CAREFUL...the two panels are not identical. One has the spot for the light bulb. Carefully replace this panel so as not to break the light. Align both panels well by pushing down so the slots re-engage the tabs, and you're done.

The lock symbol means the buttons are locked to stop kids etc or accidentally changing the settings. The owners book should say what to press to unlock it. Most of the time, 1 or 2 of the buttons need to be pressed down for a few seconds to unlock. I have no idea which buttons.

I am having the same issue. I've just replaced the filter and it started leaking out of this hole, where it never had before.
I am thinking that maybe the filter isn't seated properly, and that's causing the leak. But I have attached a picture of the hole in question. Any advice would be helpful. Thanks!

which model XL series do you have? There is obviously something shorted or arcing on the plates of the cell. look at the plates and see if they are laying flat and the wires are all still attached across the front of the cell. A loose, sagging, broken or bad contact on the end plates will cause the bad cell lights. clean off the area where the cell makes contact inside the unit. The metal strips that run across the ends of the cell make contact with the plates inside the cell and get their power from them, dirty contacts in any part of these contacts will cause the problem. Even a bad contact from the end cap to the plates inside the cell will cause this. Try wiggling the cell around, kind of push on it on edge to get the plates to shift slightly and clean the points where the plates touch the outer strips on the sides. Check for arcing with the lights turned off,

Solution, perhaps...

All electrical contacts can get a film on them. Try cleaning the contacts (at the bottom of the blade unit; you should see the three with the blades out) with an alcohol swab (make sure the contacts are dry before reassembly in this case) or a pencil eraser (vacuum the debris out before attempting to start it again).

If those contacts don't make up properly, the unit will think it needs cleaning, even though it doesn't.

HEPA is a type of air purifier. It stands for high-efficiency particulate air. To qualify as a HEPA filter by government standards the filter must remove 99.7% of all particles larger than 0.3 micrometers from the air. The following site lists the top 10 HEPA purifiers available online -

I would verify that all the parts you removed are properly seated back in their exact locations.
There is undoubtably a safety switch that is not properly closed.
A door, a panel, or a latch that is not properly seated and closing the safety switch is probably the cause.
