Thread: How to i start the Tub Clean cycle in my LG washer?

I just bought a LG WM2466 and not sure how to start the Tub Clean cycle. I follow the instruction in the booklet but the light on the TUB CLEAN doesn't light up when i press it down for 3 sec. Please let me know if i did this right, or the right way of doing it.

1. start the washer
2. add bleach
3. press the tub clean button for 3 sec.

but instead of the tub clean button light up, it's the pre-wash/child lock button that was lighting up.

Thanks.
