Billy Bob for Model Number Kenmore Elite Dishwasher - Model 665.13759K601 My dishwasher had the thermal fuse (located in the control board) fail, and so I just had it replaced (and it failed again midway after the first use). I tested the high-limit switch, and it tests OK, and the existing heating element tested within ohm spec. Do you know if the heating element can be faulty even though the heating element does heat up and tests within the expected ohm range? I opened the door of the dishwasher unit immediately after the latest (brand new) fuse blew, and the water level inside the bottom of the dishwasher is at a level that just touches the bottom of the element [noted moments after the most recent (brand new) thermal fuse blow (mid-cycle) ] ... can a heating element that does heat also be shorted, or can the element also draw too much current and causing a thermal fuse to blow?
Answer Billy Bob, A few things you may want to check. Make sure there are no loose connections especially at the junction box where the power supply enters and attaches to the dishwasher wire harness. Check and make sure the entire thermal fuse kit W10258275 was installed and attached properly(especially the jumper wires and connectors). You can use a meter and test from each element terminal to the tub bottom, and check for a possible short between the element and the chassis, The thermal fuse can react to both current draw and heat, but based on your information "the water level inside the bottom of the dishwasher is at a level that just touches the bottom of the element" the element circuit shouldn't be an issue.

Answer BillyBob, The heating element can draw too much current and cause the thermal fuse to blow or there could be too high of an amp draw on the motor of the unit. Read More... Answered by AppliancePartsPros.com | Wednesday, August 16, 2017
