EXCELLENT! After the nearly 6 week nightmare dealing with Sears in trying to get this repair done Superior Appliance Service was an absolute breath of fresh air. I called SAS on Monday, 8/19/2013 well after 5pm. The phone was answered right away. I explained the problem and informed them that I'd had a service call with another provider and knew what the issue was. I was asked very specific questions about what the washing machine had been doing (or not). Once I explained that it would spin but not drain properly and I got F21or F20 error messages, he agreed that it was the water pump. He said this was a common issue with these machines. He asked if I had a model number or id number for the water pump and I provided it. He said he'd have to check to see if he had the part but wouldn't be able to verify until Tuesday, 8/20 in the morning. He said if he had the part they'd be able to come Tuesday after 3pm. Needless to say I was ecstatic at the possibility that they might come within 24 hours. He told me I would receive a call first thing Tuesday morning to confirm everything. I received a call shortly after 9am on Tuesday morning. The part had been secured. I asked if they could come after 5pm and was given a 2hour window between 5-7pm. I was told that the serviceman would call me 30 minutes before his arrival. I received my call 30 minutes beforehand as told and pulled into my driveway at the same time they arrived. The serviceman arrived with a helper since I informed them I had a stacked unit and the dryer would probably need to taken down to fix the washer. They inspected the area and called me downstairs to show and explain to me where there were drainage issues and inappropriate installation of some parts of the unit. The explanations were very simple and I appreciated that along with cost effective recommendations on how to resolve the issues. The repair took 20-30 minutes. Once completed I was shown what caused the pump to stop working (socks, keys, loose change getting caught in the pump). They cleaned up very well, put things back in place, and told me to put some bleach down to kill the smell. We completed the payment, he explained the warranty and they left. They completed the job within an hour! They are by far the best service repair provider I've ever had! Competent, capable, professional, timely, responsive and neat. I am a happy camper and would highly recommend SAS!
