Lower Washarm

Marc for Model Number maytag mdb4030awb

Answer Hello Marc. Make sure the water level is high enough. Should be up to the bottom of the heater. If not, replace the water valve. Also, you can clean the spray arms on the unit. 

Richard for Model Number mdb4000awb

Answer Richard, We here at APP are not aware of an "on going" issue with the 99001788 lower spray arm. There was an issue, approximately one year ago, but the manufacturer remedied that, almost immediately. Please contact the APP Customer Service Team, with your previous order number and information, so we can get you up and going. Thanks

Answer Hello Barbara. Unscrew the nut in the center of the washarm and lift off the lower spray arm. Then remove the screws out of the cover and lift off the cover. Now you can lift out the filter 99001791. Hope this helps.

Mike for Model Number DWU9302AAE

Answer Hello Mike. Yes, if the filter is dirty, the water does not go back into the sump and it will not spray. You need to clean the filter first. Thanks. 

Vin for Model Number MDB6000AWA

Answer Hi Vin. No, you just unscrew it and lift it up. Then you can unsnap it off the filter guard to use a pick tool to clean out all the jet holes that get plugged and effects cleanability. Thank you. 

Glynn L. for Model Number MDB4000AWX

Answer Glynn, Your pretty lucky, it's an easy change out. Remove the lower rack, and unscrew the wash arm nut and nozzle 99001428 remember the nozzle orientation, so when you re install it, it has a specific orientation. slowly and carefully lift up on the spray arm and cover assembly. Unsnap the spray arm from the cover. reverse the procedure and test the unit for operation. Thanks and Good Luck.
