Jerry S Bridgeport , CT November 02, 2014 Appliance: Maytag Undercounter Dishwasher MDB4651AWB0 Maytag Dishwasher Mdb4651awb0: Small door leak on my maytag dishwasher. How to replace Inner Door Panel. Small amount of water started leaking from the left side during the wash cycle. Upon investigation and the leak getting worse over a few leaks, I found that the bottom of the inner door liner was cracked. It should "cup" over an inner lip but the now 1" crack allowed water to flow past the crack and drip onto the floor. I replaced the inner door panel for less than $100 and saved hundreds on buying a new washer. My only problem with the installation was that I had to trim a little (ever so slight) excess plastic from the keyway on the panel steam vent before the vent cover would fit back on correctly. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
