My Bosch Dishwasher gives off a smelly odor and appears to take longer than usual to complete a cycle. It was recently re-installed after we renovated our kitchen. Filter appears to be clean.

Here is an excerpt from "Bosch Dishwasher Troublesoooting".

Running a Test Cycle
Bosch dishwashers have a test cycle which can be run as a troubleshooting measure. The method to run this test cycle is similar across the Bosch dishwasher range so if your dishwasher features seems different from those described below then try experimenting, as the process is fairly straight forward and will be very similar. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in. The other key difference is whether your dishwasher has a display panel (which can display error codes) or not (in which case a program light will illuminate to tell you the fault.
To run the test cycle hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Whilst held down press the ON/OFF button. The lights above them should flash. Now you can check the status of each dishwasher program by pressing its button. Now you can run the full test cycle = Press the POWER SCRUB PLUS and REGULAR WASH buttons again. The dishwasher will start up and when the cycle has ended one, if you have no display panel on your dishwasher model the indicator lights will illuminate if a malfunction was detected as follows -
CLEAN - A temperature sensor fault. If this is the case then the test cycle will be very short as the dishwasher will terminate the test once it's been detected.
RINSE/DRY - A water sensor/filling fault. If this is the problem then the test cycle will not complete as the dishwasher cannot detect the right level of water, the dishwasher will just keep filling and draining again.
WASH - A heating fault. Check your heating element.
If you do have a display panel on your Bosch dishwasher then after the cycle is complete an error code will be shown if a fault has been detected. The error codes are as follows -
0 - No errors have been detected.
1 - A water sensor/filling fault.
2 - A heating fault.
4 - A water filling fault. This can also appear as F on the display during a normal cycle.
8 - A temperature sensor fault.
When troubleshooting your Bosch dishwasher, running the above test cycle is a good start in diagnosing the problem and should give you an idea of where the problem lies with your Bosch dishwasher and what fixes and repair are in order. Our general troubleshooting page will give you some ideas on other things to check on your dishwasher. Good luck!

The fact your machine gives off an odour and a slow cycle seems to point to a blocked pump, Disconnect the machine from the main power supply, Remove the back and you will find the pump located at the bottom of the machine, Remove the large hose by squeezing together the retaining clip and you should find it is clogged. Clean all filters within the machine and it should clear the odour and help the machine to run better.

Hello Peter, Welcome to Fixya. I'm going to start by asking a couple of questions, but that is part of a proper and thorough diagnosis from afar...in my opinion. Does a "normal" wash cycle take longer then 2 - 3 hrs ? Do the dishes appear to be dry when the dishwasher completes the cycle ? Further to this question, does there appear to be any heat in the machine upon completion of the cycle ? I ask these questions specifically because heat is a crucial factor in desolving the detergent ( usually a minimum of 145F ) and thus cleaning the dishes as well as allowing the dishes to dry properly when cleaned. If we could start here I will be better equipped to helping you solve your dishwasher troubles and with any luck assisting you in repairing it yourself. I'll watch for your reply and we'll go from there. macmarkus :)

every bosch dishwasher unit is different. you can get odor from different source. #1 solution to fight odor is the proper maintenance. every month run the cycle with just a cup of vinegar on a hot wash. i am a old bosch tech and alot of people dont add the jet dry properly. this is for drying,spots and-cleaning you must add the jet dry or rinse agent (same thing)into the compartment. close compartment,then lower and raise door 3 times,then fill again repeat until you cant add anymore then it is filled.if this help please send me a 4 thumbs up post. thanks

Bad odor is caused by something besides wet dishes.

When the water finishes it's part and is exhausted, does a fan come on and run for a long time? If not, the drying fan is bad, usually mounted on the side and runs after all the water is removed. Also, after the water stops, are the dishes and inside HOT? You have to have HOT water to make a dishwasher function properly, will also take care of some of that odor. When a dishwasher cycles, it washes and then heats the inside of the washer, then it runs a fan to remove the water and dry the dishes.

Make sure your dishwasher is hooked to the HOT water line and also check to be sure it can heat it's own water, put it on pot's and pans and it should heat the water quite hot, even if it has hot water coming in, it will heat it up some more.

This is just a suggestion, run a cycle and after a few mins of it washing, open the door and add a cup of bleach and let the washer run. See if this helps.

After you have unloaded the the dishwasher, prop the door open with the upper rack out.
Let the inside air out. After a short time the remaining moisture will evaporate. Stainless steel dishwashers are prone to an odor if you do not use the machine daily. There are after market products that are citrus based that will help. Check with Bosch.

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.

is your dishwasher less than a year old? if so you need to call bosch and have all the gaskets replaced. they tried a new chemical to make the gasket but now have found that after the dry cycle the gaskets put off a strange odor like your discribing. ive changed several gaskets because of this
