When I replace the filter I can't get the unit to start working again. Is there something special I should do? I took out and placed back in the new

Put the old one back in for a minute to be sure it still works with the old one.......

MAke sure the replacement is inserted to same was as the old(gray side up) and that the small lever on the left side is not bent as the filter must make contact with the lever when re-inserting the filter- it activates an internal switch before you dial in a fan speed. If the problem still persists contact germguardian.com as they are very helpful & if its still in the one year warranty period they might offer a replacement unit (that happened to my unit)

I have the same problem. They sent me new filters but that didn't help. So, probably not.

Seems like it's faulty to me. I just replaced my filter with a new one and the flow is the same as the one that came with the unit.

When I got mine out this winter it was doing the same thing but I had put new filters on it and think them weren't soaked yet. I changed the water and restarted it and the thing has been working ever since so that is all the help I can be.

Your pump and the rest of the filter system needs a good cleaning. Take everything apart and clean it and it will work again. You can find a cleaning kit of brushes the right size for all the openings here on Amazon. Also, you need to be replacing the charcoal filters as needed.

The filter starts back up again. If it spins but doesn't pull water up and through, pull the tubing up and drop it down into the shaft. That works for me.

Sorry, I can't help with this. I returned the item due to poor performance and didn't have it long enough to have to clean the filter. Good luck.

My first assumption is in the filter wiring, or construction. This is assuming you are not using any other cables. If you are, first try changing the cable, and see if it helps. If not, contact Amazon about replacement.

Is this a new filter unit? If it is new, sounds like defective to me. My experience has been that the filters always end up leaking when it is time to replace. Quality of workmanship and design is not directed at longevity.

It's definitely the filter, if you have a new filter replace it if not take the filter out and see if it still happens, I had a exact same problem, replacing the filter took care of it. I even tried to clean the filter but that didn't help.

I have the same situation, but after a much longer period of use. My second filter was at the stage when the light would flash red. Before I replaced it, the light stopped working. I replaced the filter, and still no light working. Checking online, I found that, with the filter out, you can access the switch for the light. I pressed it and the light activated. Put the filter back in and it didn't work. Repeated a couple more time, with no success. I also read online that there is no direct relationship between the light and the filter itself; it simply tracks water flow. I have decided to keep using it until there is an obvious change in either flow rate or water quality. I have the same situation, but after a much longer period of use.

I was finding it impossible to unscrew the old filter, too. Then I tried putting the whole assembly in a bowl of hot water for a few minutes, and that did the trick! I also gently slid the edge of a thin spatula around the circle where the filter meets the housing, if that makes sense. Not sure if that did anything, but the warm bath definitely helped. I was thinking I'd have to trash it and replace the entire unit before I tried the hot water. Hope that helps.

Not a problem with mine. It could be a clogged filter or to much pressure/flow from the supply. Replace the element and/or turn down the flow rate.

This happen to me once and I hope this will solve your problem. I just change a new filter.

Nothing like stating the obvious but did you allow your filter to dry out completely? That would be an important step and if your not sure try washing it thoroughly and dry at least over night to 24 hrs. I've washed mine and honestly let it dry out a few days before I attempt using it. I hope that helps.
