My washer would require several bangs of the lid to get it to start, and once it started it would fill up with water and then do nothing and just sit there.
I called Paul, he said it was probably the lid sensor and the quote would be $100-$140 total. Paul arrived, and sure enough it was the lid sensor.
I figured a new/used washer/dryer on craigslist would be $200-$250 (and $400+ at Lowes/Home Depot), and this was a much better route to go, and it was.
Paul arrived on time, was even early, diagnosed the situation, replaced the sensor, and fixed the washer in under 20 minutes. Now it's good as new.
Very polite and knowledgeable. Would definitely recommend.
