Shuts off and blinks when using Hi-Temp Wash

Whenever I attempt to use the (Hi-Temp Wash) on my dishwasher it seems to work fine for a while 30 minutes or so, sometimes longer. Then 90% of the time the dishwasher will stop work and flash the error and I have to do a reset. It resets fine every time and works fine except for trying to use high-temp wash. High-temp wash always triggers the error/shut-off.
