Here's one, also on a hydro- The job was a brand new 5 stop, standard bore hole, submersible, Maxton UC5, 60' remote m/r, with an MCE PHC 1000 control. The machine room was hot, because being the Marine Corps, the Feds didn't have to comply with the code mandated temperature maximum. They stuck the tank and control in a boiler room! The Federal Government is exempt from common sense, you know..

Customer would call and say the elevator just wouldn't respond. Everytime I got there, the thing had already cooled down. It kept shutting down on a maximum number of relevels. I forgot what that fault is called, but after 60 relevels, it triggered the MLT shutdown routine. I'd reset the fault, and run it for a bit, but it always ran great, with no problems. Then after I left, it would happen again. Where would you start?
