Calypso pump and CE error

[laitala]

2002 Kenmore Calypso washer.  Got a CE error and machine won't run.  A friend has the same machine and he said to check the pump.  As he had to replace his a few years back.  All diagnostics bring back the CE error as soon as I start the key dance.  I took the pump off and it does seem to turn hard.  My friend told me that a new motor/pump combination has replaced the old inferior one like mine.  I'm confused because when I called Sears they gave me quotes for both the pump (part number 8527633, $125.49) and the motor (part number 8054968, $155.49).  I don't want to buy the same inferior pump if a new and better assembly is available but where do I get it?  Also can anyone tell me if they think I'm on the right track here.  I have tried everything that the manual and tech sheet say:cleaning and reconnecting terminals p2 to p4 between the machine controller and motor controller, and making sure all electrical connections are tight to main drive motor and pump motor.  All help is gratefully welcomed.  Eddie

either part number typed into that nice "Search by Part Number" box on the left,
will reference the newer replacement part $ 102

Thanks for the heads up on the "nice" part number search engine at left.  I did as you recommended and there it is.  $102 is a good price too.  Do you think my pump turning too hard is making the motor overdraw amps and cause a CE error ?

look in it and get the stuff out it.

I've looked in it with a flashlight while turning it both ways and I can't see anything in it.  It seems like a sealed unit that has been epoxied together so I don't think I can get it apart without destroying it.  Any ideas on how to clean it out?

Flush it with water, also check the hoses.

thanks for the reply.  I flushed the pump with water both ways, and even tried turning it while water was flowing into it from the tap.  It still seems to turn hard, and I can't see any debris if I look into the pump with a bright flashlight.  I took off both of the pump 1" hoses and bent them straight while holding them towards the window, they are free and clear.  I tried to do the same with the drain hose but couldn't see daylight due to the check valve/flaps inside the hose, but I can blow through it easily and put fresh water through it easily, and it quickly drained the tub when I was draining it prior to tipping it over onto it's front side. 

I still can't figure out if a bad pump or pump motor would cause the CE error.  No technical manual or person has confirmed/denied this in anything I've seen yet.  I wish I could be more sure before ordering a $100 plus part for a 7 year old machine.  But it was a really nice running machine before this.

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
CONTROL CHECKS.
CONTROL CHECKS
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.
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.
