I have water in the discard container and wet grounds. They used to be dry brickets.

There were other systems as well like Halon, which is no longer used and CO2 systems, which I am not even sure if they still use either since they now have a water fog system that I am told works very well. Maybe I should investigate and see what they have come up with since I retired.

Rinse it well with hot, soapy water and allow it to air dry.
Once it is dry, take some loosely-crumpled, dry paper towels or napkins and leave them in it for a week.
You could also either fill the container or put a box worth of baking soda into the container and leave it for a week. Discard the baking soda afterwards or use it to clean your toilet.
Either of these should eliminate or dramatically reduce any foul odor.

Canned cat food has some advantages: it does not require as much additives, it contains morewater, it has higher amount of animal protein, and it contains much loweramount of carbohydrates than dried food.

Discard the first few batches of ice made by the ice maker. If new plumbingconnections are installed, discard the first few batches of ice. The plumbingsystem is flushing and may cause a bad taste or odd color. Discard ice stored in the bin for long periods of time. Wash the ice binwith warm water and mild dish detergent. Dry thoroughly before replacing thebin. Place foods in airtight containers to prevent the transfer of odors.Thanks and hope it's helpful.

i figured it out on my own  Many thanks

Several possible problems:
1) Did you clean the blue lower pickup container (dirty water) before putting it away?
Take out the pickup container and open it up, check the filter (under the little blue piece on top) and also open up the container itself and clean under the flapper on the "screen".
2) Look inside the housing and check the vac hose that goes from the front of the unit up to the rubber grommet where it goes into the lower pickup container. Is it clogged? If yes, take off the front pickup (the part the runs along the floor in front of the rotating brushes) and run a very narrow lint pickup brush (like for cleaning dryer vents) and clean out the hose. It works great.
3) Check the front pickup for clogs and clean
4) If you are trying to pick up water, make sure the setting is set to wet. If you are trying to use it as a vacuum, set it to dry.

Hope this helps.
