Well, yesterday I went to the management office and damn near blew a gasket (plumbing pun intended). That got some attention. The 2nd appliance repairman is coming back after telling management he did not check out the DW electrics on the first visit. The reason is beyond me, but when he was here the first time, he very graciously explained to me how the DW and disposal were not connected in any way, other than draining through the same drain. Obviously, he was dubious that what I said was happening could happen. Of course, he never stayed for the cycle to shut down and feel the disposal casing when it tripped the reset button. If it turns out it's NOT in the DW electrics, THEN management will get a licensed electrician up as their next move. Regarding all the electrical info in the previous responses, would that be a building-wide problem or just with my kitchen island, if anyone can answer that? Thanks.
