Question about Whirlpool Dishwashers
Hello, Welcome to FixYa.
Based on your post I understand you have a drainage problem with a Whirlpool dishwasher. typically with these machines having poor washing and incomplete draining it can be chalked up to obstructions in the sump assembly. Here's how to inspect it and clean it if necessary.
Try this link if you think you're not too confident. They aren't pros, but it is a good guide for accessing the sump assembly relatively easy. This combined with my tutorial you should be fine.
1 ) Remove the turbo wash tube if applicable to your model, it pulls off, i.e.
2 ) Spray arm removal. hold the center nut and spin the arm.
3 ) Now you can remove the upper spray arm supply tub or referred to sometimes as "rear feed cap".
a ) lift to Whirlpool dishwasher Model DU1345XTVQO, Serial - 87fb0d6.jpg rear tab, i.e.
b ) Then twist the feeder to the right ( clockwise ), i.e.
4 ) Now you can remove the center nut...
Then remove the four # 20 torx head screws holding the filter in place, and lift the filter out.
Below the filter you`ll find food debris, undissolved detergent etc, but also a cover with a single #10 torx head screw to remove and the cover will pull straight up and out. the arrows from left to right in the image indicate...
1) screw location
2) tab to pull up on
3) the latch you may need to twist to the left to remove Whirlpool dishwasher Model DU1345XTVQO, Serial - macmarkus_416.jpg
Now you should see the chopper and screen asseWhirlpool dishwasher Model DU1345XTVQO, Serial - macmarkus_615.jpgbe clogged up pretty bad, clean it best you can...you don`t really want to remove this part.
NOTE: Pay particular attention to the area where I've placed the arrow. It is a back flow check valve and can get debris stuck in it allowing water to back flow into the sump after the drain cycle ends, hence you get water left behind.
The other thing to inspect is the drain. The proper drain should actually be tied up at least as hi as the top of the dishwasher and the closer to the machine the better, but if it drains into a sink or disposer right next to the machine as long as it is tied up under the sink it should be fine...you also want to rule out any kinks in the hose of course.
Now you'll need to run a "reset" test sequence to observe it's performance. Press the following buttons in this sequence...
HEATED DRY - NORMAL, HEATED DRY - NORMAL, HEATED DRY - NORMAL
This diagnostic cycle may take approx. 15-20 minutes to complete. Let it proceed through to completion and you should be good to go...unless the pump itself is at fault...we'll cross that bridge if OR when necessary.
Let me know how you make out, please keep me informed if you need further assistance or anything is unclear.
Please take a moment to rate me assistance and a short testimony is appreciated as well.
Thank you for choosing FixYa and good luck.
