Hugh B Kaufman , TX November 02, 2014 Appliance: Maytag Undercounter Dishwasher MDBH979AWB4 Maytag Dishwasher Mdbh979awb4: My cleam light flashed 7 times. How to replace Dishwasher Heating Element. Replaced the heating element on the dish washer. after you change it out the way to reset the fault is to press (High temp wash - heated dry - High temp wash - heated dry). it will send the washer into a self check & all the lights will come on. you will be ready to start the washer up now.
