WTW6600SW Won't stay balanced

7 posts in this topic

Good Morning Fellow Appliantologists!

 

First off, I am fairly new at this appliance repair business, so hopefully this is something simple.

 

I have a customer with a WTW6600SW that will not stay balanced.  The first call I went out on, the machine was not level.  I leveled it, then had them show me how they load it.  They loaded it fine.  It seemed to work fine when I left.  A week later they said it is doing the same thing.

 

I went back out and got the following codes: F70 (overloaded), and F51 (Motor RPS sensor).  I tested the RPS sensor through the diagnostic mode, and the lights are doing the right thing. I checked that it was level. So then I loaded the machine only 1/2 way, and evenly.  It still goes way out of balance.  I checked the tension on the suspension for the tub, they all seemed even and they move.  Then I moved the washer to another part of the floor tested it and am having the same problem.

 

Any suggestions would be helpful!

 

Thanks

Welcome to Appliantology!  

 

Tip the washer back and check the rotor bolt to make sure it's goodntight.  

 

F71 is also a suds (Sd) error:

 

 

Sd is displayed when the machine/motor control, by analyzing drag on the basket, detects a suds-lock condition, and is steady on while the control then runs a mini-clean out cycle. If the clean out cycle is unable to correct the over-sudsing problem, the cycle ends and Sd flashes in the display. This may signify:
• Excessive detergent usage.
• Basket cannot engage during drain step.
• Mechanical friction on drive mechanism, not allowing basket to engage.

 

 

 

There's a service bulletin out on the F51 error:  

 

 

 

 

condition:

The electronic control displays an F51 code.

cause:

There is an intermittent connection at the Rotor Position Sensor, (RPS), causing the electronic control to indicate an F51 code.

correction:

Remove and reinstall the connector at the RPS at least three times to clean off any corrosion built up on the connector and RPS due to the intermittent connection. Confirm that the connector is fully seated onto the RPS control upon final connection and verify there are no damaged wires.

Replace the electronic control with part #W10130544. This new control is designed to check the RPS sensor differently and is less sensitive to intermittent RPS connections.

I think the key is the off balance spinning when the tub is empty.  This usually happens because the drive shaft has become rusted or corroded and is not allowing the inner basket to drop down squarely when the unit drains.  Try lifting up on the inner basket and dropping it back down hard to seat it properly.  If this makes it spin smooth again, then for sure the shaft is shot.  You can sand those smooth again, but it usually comes back.

Sounds like there is no real need to replace the RPS sensor. 

 

The washer goes way off balance wether loaded or empty.  I will have to try that lifting up on the tub and re-seating it.  Thanks

I had one that was bouncing all over the place & I replaced the suspension rods (They came as a kit) & it completely solved the problem. I was amazed, because the old rods appeared to be fine...crazy!

Check the bottom of the basket for wear also. Just had one recently that needed a new basket, new hub, and new shaft. Critical.

I tried re-seating the tub, didn't help.  Customer wanted a new washing machine after giving her prices on parts and labor.  Luckily she bought her new set from us!

 

Thanks for your help!
