Heating failure (722 series) on Kenmore dishwashers.
KenmoreAll Kenmore dishwasher codes
On a 722 series model, HE means the water isn't heating as expected. The element may have failed, or its sensor, the pressure switch or the control board is faulty. Water that's extremely hot, around 190°F (88°C), points to a heater relay stuck on the board.
Compatible models

How to fix Kenmore HE
Feel for overheating
If dishes or the door feel far hotter than normal, turn off the breaker and leave the dishwasher off. Don't open the door on a cycle that's steaming hard.
Check the hot water supply
Run the kitchen hot tap until it's hot before starting a cycle, so the dishwasher starts with warm water.
When to call a technician
Sears PartsDirect recommends a service technician for this one, since finding the fault involves live voltage checks on the element, pressure switch and board.
