Christine C Branson , MO June 27, 2014 Appliance: Maytag Undercounter Dishwasher MDB4630AWB5 Maytag Dishwasher Mdb4630awb5 / : Broken detergent latch in my dishwasher. How to replace Dispenser. I removed the front panel, a few screws and a small plug, then simply replace the broken part. The funny thing is that it has been broken for months. One night I was fed up, ordered the part and it was installed within 2 days of that decision. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
