Zanussi Dishwasher DW 915. At the end of the cycle, some dirty nasty smelling water is left at the bottom , and some dirty water is left on the underneaths of the glasses and cups. Have you a solution?

Do you have an airgap valve on top of your sink or counter? Some times routed through an exterior wall. Their purpose is to prevent dirty water coming back into the DW and sitting. You can tell by looking under the sink as well. Your DW drain should never go directly to your garbage disposal or peetrap.

yeah there should be a bit but the bottom should also have dishwasher salt in there. this is the bottom. the salt helps kill smells also helps cleaning. when you bought the dishwasher it should of come with a funnel thats for filling the salt into the system.

ensure filter in bottom of machine is not blocked. if clear
suspect blocked pipe or defective evacuation pump.

i hope this was helpful

Hello,
You seem to have a blockage,have you checked the filters lately.Also check the drain hose and the pipe that the drain hose goes into,if they are clear then the blockage is down in the bottom of the dishwasher in the pipes or the drain pump.

Hope this helps.

Thanks for the clarification (we get a lot of people on here that don't know how to really use a dishwasher).

Sounds to me like the DW may need a through going over.

Confirm the make and model of the DW so I can see how it's built. I am suspect that with all the food particles and film you mention, that the spray heads are clogged in the spray bars, and, check that the drain hose is not kinked, and it's attachment into the garbage disposal is clear. I've had these clog before, limiting the ability of the DW to get rid of the dirty water.

you can try a product available at appliance parts stores called YSANO and follow the directions on the bottle. you can also try dumping in the bottom of the dishwasher about 6 - 8 cups of white vinegar and running the machine without dishes in it. hope this helps.

your machine is likely not getting rid of all the dirty water after the wash cycle. you need to make sure there is no debris left in any filters in the bottom of the machine and see if there is a part called a check valve somewhere, it may need to be replaced.

What is the manufacturer and model number of the dishwasher?
Here is the process I would follow to remove the gunk.
Start a short cycle in the dishwasher, without adding detergent powder and after the (hot) water has filled the DW and the wash cycle has begun, open the DW door and add 1/4 cup of household bleach. When the water drains and begins to refill for the 2nd wash cycle, check the dishwasher to see if anything has gotten better and if not, add another 1/4 cup of bleach as soon as the hot water has refilled. Allow the DW to finish the full cycle.
Begin another short wash and as soon as the initial hot water fills and the wash cycle begins, open and add 2 cups (approximatly) of white vinegar. Allow the whole set of cycles to finish and check the insides.
If grease remains, I would use a de-greasing spray (avilable at all hardware stores and most food stores.) Spray on and use paper towels on all surfaces.
Because I do not know the make and model # for your dishwasher, I can not give you a part number for replacement racks.
Good Luck!

check drain hose and drain pump.End of drain hose must be in same
level with machine.Try it.

All DW that I know of will have water sitting at the bottom.. it keeps the seal moist..check your drain line make sure its clean and not clog... when your DW goes into drain listen to see if its drainning like it did when you first used it... I'll check back later..
