If there is any breakdown in communication between the
machine controller and the motor controller, “CE” flashes
and the unit beeps once. Units with repeated CE errors may
be diagnosed as follows:
SERIAL COMMUNICATION CHECKS
1. Check for contamination on P4 of the machine controller
and P2 of the motor controller. If contaminants exist,
disconnect power to the unit and gently scrape any
contaminant off the pins.
2. Check the resistance values between the serial
communication pins with the connectors in place
(resistance reading should be less than 10 ohms). Make
sure the harness is connected properly.
3. After ensuring integrity of this connection, run the unit
again to see if problem still exists. If so, continue with
1. Check motor winding resistance at P6 of the motor
controller (in the console). If an open circuit is found, this
is an indication of problems with connections to the drive
motor or the motor itself. See DRIVE MOTOR CHECKS.
2. If winding resistance is correct, check motor controller
fuse; if open, replace motor controller.
DRIVE MOTOR CHECKS
1. Check connection of the lower harness to the drive motor
and pump motor.
2. Check if the drive motor thermal protector has opened.
Check pump motor windings by removing connector P5
from the motor controller board. Check for resistance
values shown in Table 7.
WINDING RESISTANCE CONTACTS MEASURED
RECIRCULATE to NEU 11.1 Ohms P5-3 (RD/BU) P5-1 (WH)
DRAIN to NEU 11.1 Ohms P5-2 (TN/YL) P5-1 (WH)
RECIRCULATE to DRAIN 22.2 Ohms P5-3 (RD/BU) P5-2 (TN/YL)
All this and more is inside the top console of your washer on a tech sheet. Get out your OHM meter if you are unsure.
Don't forget that if you order a new pump from Repairclinic, you can always return it if it does not solve the problem.
