Heater might be faulty or the thermal cutoff has triggered.

you need to provide the full model number of the dishwasher.

Kenmore ultra wash dishwasher gets stuck at 42 on the control panel


Be aware that all (well, almost all) dishwashers have a "thermal hold" period in their cycles. This is the point in the main wash cycle where the heater is turned on to heat the water to the optimum wash temperature (about 150 to 160 deg F), and during this time, the timer will stop advancing. Once the water has reached the desired temperature, the cycle will continue. IF it does not, then you have a water heating problem. This could be caused by a bad heating element, a bad controller, a bad thermostat or temperature sensor.

Changing washing machine heating elemant


washers dont have heating elements, they use hot water from the hot water tank, most likely clogged screen at either end of the hot water hose, replace or clean screen(s) check for screen at water valve, bad,weak or burned solenoid on water valve, replace valve, reason wash cycle is long----- water restriction during fill and rinse cycles they are controlled by the water level switch

Get error message F5 about 3 minutes into the cycle, have to reset multiple times to override


F-5 Water temp sensor failure
If during the water heating step in the wash cycle, the water
temperature sensor (NTC) value is out of range, the "F/05" error code
will be displayed. Possible cause/procedure:
1. Unplug washer or disconnect power.
2. Check the water temperature sensor. Refer to the
"Water Temperature Sensor" section. Check
connections to the water temperature sensor.
3. Check resistance of heating element, if present on this
model. (abnormal = infinity)

Model # dwu7702aae has heat delay light coming on during cycle. Why?


Heater is used to both heat water during clean cycle and dry dishes after wash cycle. Most washers have either a separate switch for Heat or Dry for optional use, or some have the water heat and dish dry options built into cycle set options.

You can save money by turning off the Dish Dry option since it is a very in-efficient way to dry dishes. Instead, open the wishwasher door after washing cycle completes, just enough so fresh air can get into, and humid air can escape, dishwasher.

Water Heat option is only needed for dried food on dishes, and is never needed if dishes are either rised off before putting them in the dishwasher, or rinsed off inside the dishwaser with a Rinse cycle, if they are to stand for a time waiting for a full dishwasher for wash.
