Elmo I Summerville , SC January 23, 2016 Appliance: Maytag Undercounter Dishwasher MDB7749SBW2 Maytag Dishwasher Mdb7749sbw2 / : Maytag dishwasher would not run bad control panel. How to replace Panel-Cntl (Wht). I took the old control panel off my dishwasher and saw that the cable was bad thus causing the buttons not to work properly. Sometimes there where lights on and sometimes they were all off and the dishwasher did not respond. I ordered the control panel on a Sunday evening had it by Wed. the install was just a matter of unscrewing all of the screws on the door panel, unscrewing the control panel, putting on the new control panel and putting all the screws back. Start to finish probably a 15-20 minute job and the dishwasher is now running like new. PS: I could not find the part listed on the website so I called the company, told the representative the part# and she found it for me. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
