Started a wash this morning, started to fill with water. Returned 5 min later to an awful noise (no smell). Opened washer and it wasn't agitating as it should have been (water level was full). Tried moving to another part of cycle, but still awful noise whether on wash, rinse or spin but nothing was moving. Took out some clothes. Same thing. Wouldn't drain (I will say after we removed the clothes I forgot to close the lid when I was trying spin in which case it wouldn't work). After watching your awesome videos I found a broken coupler on the motor. We replaced the coupler and the dog agitators. .The coupler was difficult to get on the transmission shank, but after some hard wacks it went on. Both the motor shank and the transmission shanks turned freely. We put it all together, and plugged it in and no there is nothing. Doesn't make any noise, doesn't appear to turn on. Checked the door lock mechanism, and that appears to be fine. Checked all electrical connections (under the control panel, and the one at the motor). All seemed fine. Also checked circuit breaker. Any suggestions or is it time for a new washer?

Now the spin cycle works but water does not fill nor does the motor hum during the wash or rinse cycle. Any ideas?

Eric, thank you so much for your advice. I truly appreciate it. We used a multi-tester and the water level switch appears to be fine. Also blew through the tube and could hear a click. Continuity tested the water inlet valve and that didn't appear to pass so we replaced it, but the new one has the same failed reading (perhaps we aren't doing it right) and the washer still doesn't work. We do not have any experience testing the different circuits so we didn't test any others. We did plug and unplug a number of them (not the timer though). However, I turned the timer/wash selector to normal wash light then manually filled the tub with water (by unhooking the cold water hose). It did not start to agitate once the water level was reached (I did the lowest water setting and filled it about 4 holes from the top). However, when I moved the dial to just after 6 minutes on the wash cycle, it started agitating (once I closed the door). Does all that make you think it is the timer? We are trying to decide whether we should replace the timer, or just buy a new washer (perhaps a Speed Queen). Any thoughts?

Eric, thanks so much for your help. We ordered a timer through appliancepartspros and it came today (we only ordered it yesterday)! I installed it and the washer works great now! It is so nice to have it working! We did have a repair guy come to tell us what part he thought needed to be replaced, and he surmised the timer, but couldn't understand why it broke after the coupler was replaced. I just wanted to thank you and the videos on this website that made it possible for us to fix it!:)
