First service call was 4/8/13. Technician Robert diagnosed problem with our Bosch dishwasher as having a cracked drain hose. He further indicated it would be necessary to replace the water valve, water line and drain pump. Dishwasher was never pulled out of the wall from its existing location for him to make this diagnosis. He further indicated black mold existed and unit needed to be pulled out for repair. He said the drain hose necessary was in stock and he would return when machine was pulled from its built in location and mold problem was removed. The machine was removed on 4/9/13 and there was no indication of mold. Inspection also showed the only problem causing the leak was a cracked drain hose. The water line was not in need of replacement/repair. Robert indicated he would return the same day when we phoned for the drain hose repair. We phoned 4/10/13 to reschedule repair and were told Robert would there before 5 p.m. We waited all afternoon and phoned at 5 p.m. when no one arrived. We were told the call had been scheduled for Thursday, 4/11. On 4/11 we phoned Robert to confirm the time and were told the part was not in and would be coming from Tucson. When asked why he told us it was available when he phoned on 4/8 his response was "someone must have taken it." Robert returned 4/12/13. When asked why it was necessary to replace the line which was not in need of repair he said because I've been doing this for 35 years and copper lines always leak. I will not warranty any work if it is not replaced. When asked why we needed to replace the water valve and drain pump he became very defense, was extremely rude and left. We phoned to request that Richard come evaluate the problem as we had had a positive experience with Richard on a service call in January. Richard agreed that we did not require everything that was on the ticket from Robert, was very apologetic and efficiently and professionally diagnosed the problem. He returned on Tuesday, 4/16 and finished the work. Richard was excellent and will be the only reason we would use Accredited Appliance in the future.
