G/E washer agitator spun freely & wasn't engaging to the transmission shaft. I found the agitator coupling (plastic) "stripped out" where it engages the transmission shaft. Very common failure point on these machines after 10+ years. Cleaned splines on transmission shaft w/a wire brush & installed new coupling & retaining bolt (7/16") Working properly again. 20 minute repair.
G/E dryer was starting when ever timer was set to time or cycle dry with out engaging the start switch. Using a meter, I found the start switch was "closed" all the time constantly sending power to the timer vs. momentarily sending a power signal as it should. (If this condition of timer turning the dryer on is not rectified it'll lead to the timer wearing out prematurely, as it is not designed to deal with on/off current duties & arcing of the contacts involved) Replaced momentary start switch & now dryer only turns on when start switch is engaged as it should. 10 minute repair.
