The unholy Trinity of appliance hell. Every brand that makes these has issues. If you get 3-5 years of use out of any of them (post ~2005) you're lucky.
I'm firmly convinced that every washing machine or dishwasher brand just wants to steal from you
I learned that a lot of machines break down because of the combination of low temperature washing and the types of soap/detergent people use. It clogs up the machines and without regular maintenance, the occasional hot wash or better soap, it destroys components.
Apparently low temperatures do not fully resolve the modern soap (which is thick and heavily perfumed), leaving behind a lot of residue. An occasional hot wash clears them.
I don't remember the name of the better soap, but basically what he says is that for clothes that are just a bit smelly but not really dirty/stained, modern soap is massive overkill. It also doesn't need all this perfume. Your clothes are fine smelling neutral, they don't have to smell like a day in the Alps.
Would really advise to talk to a local maintenance guy, they can probably explain it much better.
I believe most front loaders these days have both a self clean cycle (you're supposed to run it every month or two, it's basically an extremely long hot water rinse+spin that you don't add soap or put clothes in for), and a drain filter that should be accessible near the bottom front (expect black slime if you haven't cleaned the filter recently).
