# LG-built Kenmore washer error code bU

### Whose code this actually is

Kenmore did not write bU, because Kenmore has never built an appliance. This one is LG’s, and it appears on the washer that LG built and Sears sold under the Kenmore badge. Whirlpool-built and LG-built washers wear one badge and share almost none of their code scheme, so the wrong table here sends you to a pump when the machine is reporting a lid.

### What it means

LG's own label is VIBRATION ERROR.

### Which Kenmore models can raise it

The Kenmore washer whose model number begins 796 — the three digits before the period on the rating plate. Those digits are LG’s, which is why LG’s table is the one that applies to bU and no other manufacturer’s does.

### What happens next

- Level, load size, and the floor under the machine.
- A washer on a raised wooden floor amplifies what a slab absorbs.

### Where this usually goes

The job this most often becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. A Kenmore washer in this county works in hard water and a warm laundry room, so a code that arrives with slow draining or long cycles is very often the supply or the drain rather than the machine. Photograph the display before you cut the power: a reset clears bU, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.

### Where this meaning came from

LG’s own documentation: *LG Owner's Manual — Washing Machine, Front Loader, USA, P/No. MFL71728911*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
