The machine works fine till the last 5 or 6 minutes of the cycle then errors out with OB message. OB stands for Off Balance. It does not seem to vibrate much during the spin mode, however, it keeps give that error even when it is empty.
Q1. Where is the OB sensor located at?
Q2. Any ideas what would the problem be?


Many Thanks

Just had OB and LD errors. LD is slow drain. Found Q-tip binding pump. OB may be because water still in tub.
Good luck

Dear Walker23838,

Thank you for your answer back.

Have you noticed a yellow rubber ball in the reservoir between the pump and the drain hose. Cleaned all the washer inside out, took the pump apart and made sure in rotates and drains fine and still doesn't work. I entered service mode and was able to the spin at lower speed with no problem; once it goes to 400rpm it gives the OB error.

Appreciate if you have any idea.

I am having troubles with the ob error code and am wondering if you were able to find a fix for yours. Thanks.

Is the drain hose sealed to the washer stand pipe?
