our dishwasher malfunctioned and we called the manufacturer to have someone fix it-since it was still covered under warranty. they refered us to appliance man. a person from appliance man called us the same day and asked the nature of the problem and said they thought it sounded like the heating element. they said someone would come on wednesday between 1:00 and 3:00. the guy showed up right at 1! how great! he checked it over, determined that it was indeed the heating element and was gone in less than 15 min. and said he'd order the part. Unfortunately it took all the rest of that week and the following week before the part came in. so i was pretty sick of hand washing by then... anyway, the guy came back (again in the early part of the expected time window) and speedily replaced the heating element -less than 30 min. - and made sure everything was in working order before leaving. no problems with dishwasher since.
