Bosch dishwasher will not drain - causing moldy odor
Dishwasher is about 7 years old and water has always remained in the in the base - not actually on the floor of the dishwasher but in the lower part where the spinning washer part it. I take a food baster and remove it to prevent odor from sitting water. Can you help?

Re: Bosch dishwasher will not drain - causing moldy odor
Hello Mimhoff it depends on how much water is down there. The sump area always has a little water in it to prevent the circulation pump seals from sticking. Usually around 1 to 2 inches. If there is more than that, check the slots at the bottom of the sump on the left side for being clogged and check the end of the drain hose to make sure it is clear. If you are getting a moldy/odor from the dishwasher, try running Dishwasher Magic or Tang thru the dishwasher. This will remove any build up of food or detergent from the dishwasher. If you are running the dishwasher every few days and just scraping your dishes, then either leave the door ajar or run the rinse & hold cycle to help keep the odor down. Bosch doesn't reccommend running bleach thru the dishwasher as this can cause damage to the rubber seals. However 2 tablespoons of bleach once a year won't hurt.

Yes you will have no problem if you use the sink, I would however recommend that you lower the drain hose after each wash to the floor (emptying into a bucket or somesuch), and siphoning any remaining water from the machine.

this may be caused by a leak your dishwasher as a build in anti flood switch which stops water from entering when it leaks into the base of dishwasher . You may be able to check this for yourself by unplugging your dishwasher and slowly pulling it out and lean it back if water runs on to your floor you have had a leak .if at this point you turn it back on it might start to fill again .if it does start to fill turn it off again . it will need further examination to see why it leaking .if you feel you can't do this call your local engineer .
To cut a long story short, lower the drain pipe as close to the floor as you can. Some dish washers have a non return rubber which holds the water in the cabinet until asked to drain.Meaning water wont just flow out with pipe being low.(Im assuming the drain pump is operating correctly).Check if this alteration makes any difference.
The problem is most likely that the drain is blocked. Remove the lower front panel on the dishwasher. You will see the drain hose connected to a small pump close to the floor. disconnect the hose and remove the pump. There will be some water so be prepared with some paper towels, or rags. Remove the small pump so you can visually inspect it on the inside, remove any debris you find. If there is no debris there go under the kitchen sink and disconnect the other end of the dishwasher hose. you can then remove the entire hose to inspect it for a blockage. If no blockage in the hose, you must then check the path of the drain water through the garbage disposal [if you have one] and then the trap.
If there's no water entering your dishwasher, check these:
Water-inlet valve Float switch Water-inlet valve
The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it.
The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.
you could fix this, however the price of repair will be 1/2 of the price of a new dishasher. I would suggest you buy a new oneand not waste money on a six year old dishwasher. find a good scratch and dent model.
Clearly a design or manufacturing flaw. I have the same model and the rack is disintegrating after 6 years. I believe it is a manufacturing flaw. Our previous dishwasher rack lasted over 20 years in the same conditions. Same construction, vinyl covered steel. New upper and lower racks cost over 200.00 and there is no guarantee that this won't happen every six years. I recommend a new non-Maytag dishwasher as soon as you can. Meanwhile, limp along with the defective racks.
