Bill October 29, 2014 for Model Number dwu7400bae Dishwasher will not start. I banged on front and it will start , but will not keep going. Do I replace the timer? Or could it be something else? thank u for your help bill
1 Answer Bill, The most likely cause for the unit not starting would be either the timer contacts not making or the door switches being bad. You will want to test the door switches for continuity and if they check ok then replace the timer. If they do not check ok then replace the switches. Read More...
Dean April 06, 2013 for Model Number maytag dwu7400bax The timer does not rotate on its own, each cycle works but the knob needs to be turned to operate them. Is the timer out?
1 Answer Dean, from the information given you'll need to replace the timer. The timer for your model is part number WP99001142. Thanks! Read More...
Gary September 11, 2012 for Model Number DWU7400Bax I installed a new timer and still have the problem which is that the DW will fill on the rinse and the prewash. It will not fill on the wash and the first rinse but it will fill on the second. The only way I can get DW to clean dishes is by adding a bucket of hot water to the wash and the first rinse. (I know to do this because the pump is running and the soap basket is open but no water in DW. The float switch is free. The brand new timer gives the same results as the old timer. Please help???
1 Answer Gary, You'll need to check the Drain hose, and make sure there is not a syphon effect occurring, and the hose is high enough for the tank to hold water. Then check the Blue #29 wire between the timer and the float switch,unplug the wire harness connector and check all the terminals in the connector, and all the pins on the timer to see that the harness terminals are properly attached to the timer pins( scratches on the pins is a good indicator), Check and clean the float WP99002363 and the float guide, and check that the float switch WP99002560 is properly mounted to the bracket 6-912656 and the lever moves freely. On this older unit, you will also want to check the wire harness in the lower right hand area of the door, The wires could be internally frayed, from opening and closing the door . Read More...
