Thank you all for your recommendations for washing machine repair. Below are the recommendations I received, in order of the number of recommendations:

Jim Wadding was by far the most frequently recommended and we had him repair our washer. It took 30 minutes and the washer is working like new again.

Thanks to everyone who submitted a recommendation.
