I need help, because I'm trying to remove limescale, hard water build up from my Maytag Dishwasher. I want to remove the top and bottom spray arms, but can't figure out how. I've looked in my manuals and called the company, not help from either place. I would appreciate any help I could get. Thanks

Hi Bird,

Remove the lower spray arm by unscrewing the cap (#34 on the break down diagram). Remove the filter guard (#36 on the break down diagram) and the cover (#4 on the break down diagram). Remove the pump housing filter (#6 on the break down diagram) and the rinse arm assembly (#7 on the break down diagram).

Soak all affected parts in white vinegar and brush them, using a soft metal brush.

I do not recommend to remove the upper spray arm - you can damage the retainer.

Assemble it back. Start the regular wash cycle. After the dishwasher filled with water open the door and pour a gallon of white vinegar in and do not restart the cycle for about 12 hours.

Restart the dishwasher and finish the cycle.

Here are the break down diagrams for the Maytag dishwasher Model MDB5000AWB

Thanks, Gene.
I will give that a try.
