Water not getting to the upper level, dishes not cleaned.
Functions properly except water is not getting to the top level and dishes are not being cleaned. A peper towl put in the upper basket is left dry and the upper wash arm does not rotate.
I have checked the water inlet valve and it works fine.

Re: Water not getting to the upper level, dishes not...
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.

Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!
Clean the internal parts of the dishwasher. Use a clean wet cloth and wipe down the inside including the racks and the sprayer arms. Remove the upper arm by unscrewing the center bolt. Clean both sides before replacing.
Check the water pressure. The dishwasher requires inlet water pressure between 20 to 120 psi. If the water pressure in the line is too low, proper rinsing will not occur.
Check the water temperature. The dishwasher performs at optimal levels with 120 degree water. Check the hot water heater for needed adjustment.
Use the right detergent. The dishwasher requires detergent designed specifically for dishwashers. Other detergents will leave spots, residue or food on dishes.
Set the machine to the proper cycle. The dishwasher offers a variety of cleaning cycles. Select the appropriate cycle for the type of cleaning required.
Load the dishwasher properly. An overloaded machine will result in dishes not being cleaned thoroughly.
replace the upper water arm conduit and wash arm hub as they leak under years of pressure and the o-rings leak water and then it can't hold pressure and supply the upper arm with full pressure water,also replace the center arm conduit if it has one as this will wear out too
sounds like a bad circulation pump. but this is how you check. once the water start to circulate and the unit is wahing open the door and see if you have a steady water droplets at the very top evenly. if you dont 9times out of ten pump is 50 to 75 % gone and the unit is not washing properly. let me know if i was of some helpto you.
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. <a href="http://tclaundryrepair.com/">St Paul Appliance Repair</a>
check water level in machine
may be not filling enough and the wash pump is starved from water thus not pushing water to upper arm
drain water from machine dismantle and clean out air tube to pressure switch take off air tube at pressure switch and blow back into sump then pinch air tube with fingers to stop air from flowing back up tube then refit to p/s
run and see if that solves problem
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.
