Question about Bosch 24 in. SHU6802UC / SHU6806UC Built-in Dishwasher

3 Answers

Bad smell This is more of a general question. When I run the dishwasher there is a bad smell as it fills with water. It comes out of the sink/garbage disposal. I have cleaned out the line that comes from the garbage disposal to the drain and that doesn't stop the smell. Is there a line that needs to be cleaned from the dishwasher to the sink or how can I fix this issue?

It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:

Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.

Most problems with smells in Bosh Dishwashers come from failure to have the 20" rise in the drain line between the dishwasher and the drain as the installation manual requires.

My factory installer failed to do this. After looking at the installation manual, which shows a 20" rise, I used electrical ties to hold the drain line 20 inches above the floor. The smell which was causing us to run the rinse cycle every day to get rid of the smell has not been back in five days.

The smell is almost certainly from the garbage disposal unit - dreadful devices! bset solution is to plumb in drain elsewhere. this is a fairly common problem

Water backs up from the drain in my dishwasher and smells. what is the problem?

Two things can cause this problem:
1. The check valve in your dishwasher may be defective, allowing water and food debris to seep (or run) back into your dishwasher.
2. Your drain hose may not be "mounted up" the way it should be. Look under your sink. Look at how your drain hose is connected to your garbage disposal. If the hose runs down to the floor of your cabinet and into your dishwasher, that is wrong. Instead, it should be mounted up so that water from the sink and garbage disposal would have to flow up first to get into the dishwasher. If you do this, then even if you have a bad check-valve in the dishwasher, it will prevent the problem (or greatly reduce the problem) of dirty water flowing back into your dishwasher.

How do we remove the horrible smell in our Bosch dishwasher?

First check out your model to see if it has a built in garbage disposal, if so, make sure it is not mucked up.
Run hot water down your sink drain while running the sinks garbage disposal. Pour baking soda down your sink garbage disposal followed by white vinegar. Let it sit and foam. Run hot water down sink disposer while running. When finished:
Run empty dishwasher with no soap, let dishwasher fill with hot water to wash and then pour 1 cup of white vinegar into the bottom and resume wash. Make sure you take it through the dry cycle. When finished, open dishwasher and let it air for a couple of hours, longer if you live in humid area. Hope these steps do the trick.

When dishwasher is emptying it is backing into sink

there is probably nothing wrong with Dishwasher itself.
Your Sink drain is stopped up or your Garbage disposal is clogged.
usually, dishwasher drain is connected to the Garbage Disposal, but if the dishwasher empties the water into the Garbage disposal, if its clogged then water will come out of the sink. Same if sink is clogged between sink and sewer.


If you fill up your sink and then water drains away, then you know your sink itself is not the problem. If its only the Garbage disposal side that does not drain, its the garbage disposal that is clogged.

Newer Maytag dishwasher smells really bad inside

This problem can normally be fixed very simply and you can do it yourself.
1. There is a flexible drain line that goes from dishwasher to the sink drain line or garbage disposer.
2 You will find this flexible drain underneath the kitchen sink.
3. Make sure that the flexible dishwasher drain line goes up above the sinks lower portion of the sink basin and then comes back down into the sinks drain line or grabage disposer. The dishwasher flexible drain line must go above the bottom of sink basin like an upside down u shape, it will act as a upside down p-trap that you see under the sink in the sink drainline.
4. Once you have the flexible dishwasher drain line in this configuration (upside down U shape or p-trap) it will prevent air from leaking out of the dishwasher as the smell you are smelling is coming from the drian line.
5. You should also look inside the bottom of dishwasherr to make sure the drain screen is not clogged up.

Bad smell coming from bottom - water doesn't completely drain out

Make sure the drain hose is not blocked or pinched.Also check where it drains into your sink pipeing to be sure food isnt blocking the drain way.
Its eather the drainage path is blocked or the pump stoped pumping.
Also, the drain hose must be installed so as to have a high spot higher than the sink drain or the water from your sink will be able to "run down hill" or drain into your dishwasher. Take a look and see!

also It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:

Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.

Bad smell in dishwasher, have cleaned and even used bleach. The smell just comes back. even smells on the dishes. the smell is like a stink bug.

Three things, dryer coil, food stuck inside.

Most washers have a one way valve on the drain and a water trap
created with the line, so no water or smell can go into the machine.

Check the valve, remove the hose,that should be under the sink,
wrap a cloth around it and blow,it should not be able to blow into it.
Then make sure the hose at some point go higher then where it
connects to the drain.

Fill a bucket and fill the washer until you see a little in the bottom of the machine, watch it for a few minutes to see if it drains, it
shouldn't, dump in a bottle of white vinegar and run the machine, make sure dry is off. Then run it again, do not add anything.

Had standing gray water under house got the water out and fixed the drain problem but still have the smell How do we get rid of the smell of the stagnent water its bad. Thanks

Many commercial cleansers are good for neutralizing odors, but several common household products can be used as well. Vinegar is an extremely versatile grocery item that neutralizes many odors, including those left behind by pet accidents and skunk sprays.

Baking soda, whether applied dry to an area or mixed and sprayed with warm water, is another effective way to absorb and neutralize household odors. Baking soda carries the added benefit of absorbing moisture, so it often makes a good secondary application for a moist stubborn stain causing an odor. Citrus fruits like lemon and oranges deodorize and leave a pleasant smell behind. Using citrus juice on fabrics is not usually recommended, but they are good for things like running through garbage disposals.

Bad smell

smell is not the fault of the dishwasher but your waste disposal unit - they stink!

it may be awkward, but arrange your drain so that there is a water barrier. better still. install a standpipe for the drain, again with a water barrier

SHU43 Bosch Built-in dishwasher

Try running citric acid (3 tablespoons) through.
You can get it from a drug store.
Or, run 1/2 cup vinegar through.
Do this in both the dish washer and the disposal.
After doing this try running some water into the disposal and then see if the next time you run the dishwasher if it still smells.
You could be having a problem with water not staying in the drain trap under your sink that is why if you run water and fill the trap, then you will find out if it was the dry trap that caused the smell from sewer gases backing up into the house trough the garbage disposal.
