Stinky front loader Bosch washing machine - what to do?

[Jeff H Young]

After a final spin, there is still some liquid insde the bottom pan, so after a few days it will have a smell due to bacteria, naturally. So before adding a new load to wash, I just dump in the basket drum couple gallon of water, wash 10 sec, then drain. Repeat again, then it's ready to wash a new load and no more bad smell on the clothes.

Don't waste your time cleaning with vinega as it will smell again shortly.

Are we trying to solve the problem from 2015 ? or is this a new one ?
