You should be able to down load a Manuel on line make model etc this will help you .

check the water inlet connection for free flow of water.

i was able to obtain a drawing from repair clinic that helped to resolve my problem.

buy a haynes or chiltons repair manuel for about twenty bucks at local parts store you will find them in back of manuel. berrydalewolf

suggest you purchase haynes repair manuel for your vehicle from auto parts store. it has illustrations and step procedures for water pump removal and installation...cost appx $20 bucks.

If Rylee's above solutions do not fix your problem the filters may indeed be the problem. Start by removing the lower spray arm. There is no need to remove the arm from what I'll call the "arm base/cover assembly"; keep it clipped on.At the center of the arm is a knurled screw. It looks like a thin disk with several bumps on it, about 2 inches in diameter. It will unscrew (lefty-loosy) and allow removal of the arm assembly. At quick glance it appears to be a molded part of the arm but that's a clever disguise. Making this part a different color would be too helpful. What else would the Maytag repairman do it they made it easy for the do-it yourselfer?
Anyway, after removing the spray arm take note (or photos) of the visible parts, i.e, spray nozzle, 2 split plastic spacers. Be sure you'll be able to return these to their proper position later.
Remove the six torx (star-shaped) screws and lift the impeller cover off. Again note/photograph the position of remaining parts, i.e. filter, impeller. You will likely find the filter clogged with debris. It can be pulled out. On my model it is retained in a groove and take a bit of force to remove. I used water pressure (sink sprayer) and a toothbrush to clean my filter.
Remove any debris from the sump/ drain area. Reassembly is reverse of installation. Be sure to flush out the arm assembly to unblock all holes before re-installing it.
I hope this helps.

Hello cljjtm,
You will need to clean the wash arm and unclog the spray holes.. use white vinegar to break down the soap deposit and a sharp metal tool such as an awl to free these holes up from any build up.. white vinegar may be applied while unclogging the openings..
Then, once the spray arm holes are freed of deposits..Start with an empty dishwasher.. and then start a wash on the hottest available setting and then after a few minutes of it cycling.. pause it and add a cup or two of white vinegar to the wash ( the white vinegar should break down any soap residue and allow it to be rinsed away)..once complete.. use about 1/3 less detergent than you have been. See if that gets your DW back in working order.. Hope that helps..
Regards,
Rick

In some machines the schematics are glued under the machine upper cover. I don't know for what purpose you are looking for the drawing, but in case you have a problem and you need for any assistance, let me know and I will try my best to help you with it.
