We've had a couple issues with our washing machine. Sometimes if the load is too big/heavy (like trying to wash the comforter for the bed), it will throw the counterweights off and cause it to shut off instead of going through the spin cycle. The issue with that is the machine will then "unlock" the front door before all of the water is drained and it will leak all over the place. The other issue is that we tried some of those dissolvable soap "packets" that you put in with the clothes instead of the liquid or powder you put in the separate tray, and if the load is too big / heavy the packets won't completely dissolve and consequently end up with a wad of soap stuck to the clothes.
So it all boils down to making sure we don't overload the machine and it runs fine.
Edit: forgot to mention that for some reason the "hot" water cycle doesn't work anymore. If I run a load with hot instead of warm/cold, it won't add any water and just tumble the clothes with the dry soap. This went bad a couple years ago, I'm assuming due to the water pressure issues we had at our last house. For some reason the hot water cycle would end up causing a "water hammer" effect on the house, which I believe ultimately messed up the valves. Either way, we just wash everything with tap or cold and the clothes seem to come out fine.
