Question about Kenmore 13742 / 13744 / 13749 Built-in Dishwasher

1 Answer

Hi I have a Kenmore model 13742k. The dishes in the upper tray are not getting cleaned. The upper spray arm is not circulating. I dissassembled the components from the base leading up to the spray arm but there is no clogging. Water does flow out of the spray arm but prob not enough to turn it. The turbo components are clear as well. Any ideas? Thanks Richard

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to because the door will be open, but if you feel more comfortable shutting off the power to the dishwasher, do so.
Good luck!

On my Kenmore model 665.13489K900, it does not clean well and appears to have a problem with getting or circulating water inside to all areas, especially the top shelf.


Check the center wash arm assembly. If the center wash arm isn't getting water, all of the dishes in the upper rack will come out dirty. Check to be sure the center wash arm assembly is mating properly with the water supply nozzle in the back of the dishwasher. Also check to be sure the little holes in the center wash arm aren't clogged or blocked. * Run empty cycle using vinegar and baking soda lime scale problem will resolve.

Top rack dishes not getting clean


Hey- Two things could be wrong.- clog, or bad motor. Sump screen needs to be cleaned of debris. Removal of sump cover to access screen requires torx bits and some patience. Replacement of pump requires pulling out dishwasher to access bottom. Motors fail when seal between motor and pump fails. Will still operate, but become weaker over time. Parts available- motor about 100$ at appliance parts pros.appliancepartspros. Hopes this helps- Thanks- ED

Top rack does not wash dishes.


Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure.
inefficient wash motor impellor (faulty)

Dirt left on dishes on top tray; bottom tray washes fine


The broken bottom arm is probably preventing any water / water under pressure to get to the upper arm.
After you replace the lower arm, you should have much better cleaning in the top shelf.
While you are in there replacing the lower arm, recommend you remove the filter under it and clean the filter and any debris you find. Be careful of broken glass!
Good Luck!

Bosch dishwasher - top row of dishes do not get clean


There is a screen that you can remove from the sump of the dishwasher to clean. Just twist it to the left and pull it out. I have some tips that you might want to check out if this does not resolve your problem.

Kenmore elite dishwasher 665 purchased in 2001


Sometime objects tend to build up under the screen and around the circulating pump. These objects will block the water ports and cut the ability of the spray arms to rotate. If you are carefull you can disassemble the unit under the bottom spray arm and inspect/clean the screen and circulating pump.

Dishes not getting clean


brittgee, there has been a number of service flashes on this model. One that has to do with the upper spray arm assy. Complaint is poor washability; gritty glasses, food redeposited on glasses, especially in the corners. They redesigned the upper spray arm to improve water spray to all corners of the upper rack. The new part number is 8269022. They also redesigned the third level spinner for more consistant rotation and better washability. This was also under a service flash. Part number.8193768. Other reasons for poor wash would be; low water temperature, rinse aid disp. not working, loading etc. Catriver...post back.

Water not getting to the upper level, dishes not cleaned.


Penrod, sounds like a circulation problem. Two things to check first. make sure the upper spray arm is not clogged with debris or split. Second is to twist and remove the filter and clear out any debris where the water enters the circulation pump impeller. If something has jammed the impeller, you would have to remove the dishwasher, remove the tank, remove the circulation motor and clean out the impeller...Catriver...post back.
