Hi, I have a whirlpool Estate series washer model TAWS750PQ0 that functions correctly and service people have been here numerous times and carefully looked it over for problems and found nothing wrong.
The only problem we are having is an ordor coming from inside the machine tub that the past techs have attributed to a small amount of water that is left behind each time it is used and stored in the outer plastic drum. The pump is almost new and functions well. We have done a load with clorox and hot water only which cures it for a short time but it comes back. The clothing washes clean with no odor. We have 2 of these units and the other one of the same age smells fine. The pvc drain piping has a prop a vent hooked to it and is not clogged. it is however hooked up to a sewer line that does not have a trap in it. The smell is unlike sewage so I do not believe that is where it comes from. This is driving my smell obsessed wife crazy and she is about to scrap it just for this problem. Any suggestions PLEASE????

Thanks for the reply. Untill recently that smell was not present. I will check for any obstruction as you mentioned but what can I do to make that smell go away? It is really a nasty odor and either we make it go away or we throw out a perfectly good washer. There must be some way to make all the water drain out. Why does it stay? We must find an answer....

I had that problem over 2 years ago. Back then I took the whole washer apart and found that greasy work clothing ( I am a car mechanic) had left a residue on the plastic drum. I scrubbed it off and the smell was gone. I also found that when using tide concentarted detergent you have to use a lesser quantity or the suds are too much and that caused it to drain improperly. I have been using this machine now still with no smell or problems.

No Problem.

As I remember it the machine come apart rather easily. Remove the screws on the back that hold the top down and lift it forward disengageing the front retainers. Take off the back plate and remove the outer shell. Most everything is then accessible. Good luck...
