You could spend half your life plus a small fortune in wasted money buying wrong parts if you go on guessing and wondering if it might be. The only way to be sure is using the correct tools i.e. multimeter and RPS test meter etc plus the knowledge of what to test & how. You then test & examine each part and eliminate that part as being faulty. The only easy part you can check is take out the copper stator and visually check for signs of over heating or burning. Do the same with the drain pump. If you have a multimeter the drain pump resistance should be approx. 33.5 ohms and the stator 32 ohms between each of the 3 windings. Apart from that call out an expert and let them check.
