Excellent and trustworthy service. Sam is reliable, prompt, knowledgeable, professional, courteous and honest. I will contact him again for future appliance repairs. My five year old GE dishwasher was leaking underneath the machine. The leak appeared to come from a brass elbow fitting that was easy to access. I decided to try repairing the leak myself. I removed, resealed, reinstalled, and tightened the brass elbow. The dishwasher still leaked after my attempt so I shut off the water supply to the dishwasher. I called Sam and he arrived within the time he said he would. He opened the water supply and ran the machine but the machine did not leak. He made several attempts to get the leak to appear. Still there was no leak. Sam told me that the symptom I described could have been due to a problem with the fitting or possibly a defective water intake valve and he had a replacement part with him. Instead of replacing the intake valve he recommended that I monitor the area for a few days as it was possible that I did fix the problem by servicing the fitting. This would save me 66% of the cost of the repair as he would only charge me the cost of the diagnostic visit. Sam assured me that if the machine still leaked within the next 30 days he would return to repair the problem and apply the cost of this visit to the total cost of the repair. He would make two visits for the price of one as he does not replace parts unnecessarily. As it turned out, the leak did re-appear within a couple of days and Sam returned promptly after I called, as he had promised. He charged me the same amount for both visits as for a single visit to repair that problem. I was very grateful for his honesty and trustworthiness in addition to being highly satisfied with his knowledge and skill in diagnosing and fixing the problem.
