Have you checked to see if there is enough water filling the tub? If there is plenty of water, then check the spray arm for clogs. After that, you are looking at replacing the main wash motor.
How does a main motor only affect the upper spray if bottom spray cleans well?
The ability of the motor to turn fast enough to push that water up to the upper rack. If a motor is failing to turn fast enough, it can have enough push to move the bottom spray arm but not enough to push it up against gravity to the upper spray arm.
If the upper spray arm is position where it points to the 12 and 6 o’clock positions, the diagnostic mode can be activated to directly identify if water is reaching the upper spray arm. Press the high temp, turbo heat dry, then the turbo zone keys quickly and repeat this pattern two more times (should be a total of 3 button press patterns). This will enter the dishwasher into a diagnostic mode where it will show initial error codes at first, then fill and start to wash using the upper spray arm. After the dishwasher has completed the fill cycle and started operating the motor for 15 seconds, the door can be opened slightly (water will splash out if it is opened fully). After the door has been open for a couple of seconds, the upper spray arm can be checked to see if it has rotated from the position it was set in. Once this is identified, the door can be shut and the diagnostic cycle allowed to complete on it’s own. The entire diagnostic cycle lasts for 23 minutes and can help identify if there are any errors found, it will show new ones at the end. Does the spray arm move or did it stay stationary?
William M, sorry, I missed this post. I will run the diagnostic and report back. Thanks for the assistance.
Ran diagnostics, upper arm did not move.
Inital codes:
F7-E1
F8-E2
At the end of cycle: E-,F-, repeated several times. It looks like no error codes at the end. Am I correct?
If the arm didn’t move should it produce a code.?
Is there a special motor that controls flow to the upper arm, or does the primary washer motor control everything?
Thank you.
The upper spray arm not moving would not necessarily produce an error code, this check was to see if anything would come up that related to the diverter motor or circulation pump. The error F7-E1 is a heating issue while the error F8-E2 is a drain motor issue. Here are some checks that can be done.
- Inspect the spray arm and water supply tower for any cracks or clogs.
- Inspect the diverter plate for any damage or clogs that might prevent it from rotating.
- Remove the front door panel, locate the connection P7. With a meter set to Volts AC, activate the diagnostic test and use the meter to immediately test from the blue wire at pin 4 to the blue wire at pin 6. Does 120 Volts AC show up around 50 seconds into the diagnostic mode?
Here is a picture of the control layout and how it would be wired. The blue lines are indicating the diverter motor wires for testing.
