Sticking hot water micro switch is a common issue that causes these old birds to overheat fixter1 .... 1st thoughts

remove the bottom panel and remove both screws of panel and drop panel down , the red neon will be on which means it is stuck in hot water mode , if you back the switch off and test with hot tap for making and breaking should sort it , good luck
