This washer will not spin on high speed. All other functions appear to work fine. The only code in "history" is F01. When running the diagnostic test, the washer DOES reach high speed, but DOES NOT during wash cycles. I have replaced the motor control unit but problem still exists. In reviewing the error code F01, it says there was a communication error between the CCU and the EEPROM onboard the CCU! What is an EEPROM?

Any help would be appreciated.

Any unusual noises during spin? Growling, rumbling or other low-pitched noises that get louder as the RPMs increase? Check for this while running the spin cycle in test mode.

Thank you for your response. (I may have replied incorrectly the first time-sorry) I do not notice any unusual noises. The machine is about 5 years old. Have not had any other issues. I'm not sure how long the machine has not been spinning properly. I remember when new, the machine would sound like a helicopter for the last portion of the spin cycle. My better 3/4's just started complaining about how long heavier items, (towels, pants, etc) were taking to dry. It dawned on me that the spin cycle was slower after actually watching the machine work.

Since it only occurs during wash, you may also want to check the pump and filter for any restriction.

 

EEPROM = Electrically Erasable Programmable Read Only Memory (chip).  And I think the one in my brain may be defective.

Thank you for the information. I did remove the pump and check hoses for kinks and clogs. Did not find anything and pump turns freely.

Having ruled out everything else, we're left with the F01 error code, which we have to interpret as the CCU's attempt to tell us that its operating system software, which resides on the EEPROM, has been corrupted. The indicated repair is to replace the CCU Part number: AP4560749

Part number: AP4560749

 

If that doesn't fix the problem, you can return it for a refund.
