My washing machine worked perfectly last time I used it about a week ago, but today loaded some clothes in and everything was sounding normal until it finished filling and should have started agitating. At that point it just makes a humming noise, almost sounds like a belt is broken maybe. I switched it to the spin cycle, it will not spin. It does drain.
Suggestions on where to start are great! The machine is in a TIGHT spot so I haven’t tried to look yet, not sure if I should look from the top or from the back. I appreciate suggestions!
Just to follow up on this, my wife let me know that last time we used the washer was for towels and it took 2+ hours to dry them afterwords, so I suspect this happened sometime during the last wash cycle and I wasn’t aware of it. I’ll be moving the washer and dryer around today to get behind the dryer, but still looking forward to some advice on the best way to start repairs. Thanks 
Ah, interesting! I hadn’t looked since we emptied the washer last night, but the tub will spin empty, does that narrow what could be going on? Motor wearing out? If I let it spin up on its own, it can, but if I hold it at all it can’t spin up. As if it has very little power.
