Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Type — SideKick pedestal mini-washer
- The SideKick is a small 1.0 cu. ft. washer built into a pedestal that sits UNDER a compatible LG front-load washer (TWINWash), for a small second load. It is a separate washer with its own water connection, its own drain and its own controls and error codes — troubleshoot it independently of the main washer above it.
- Capacity limits are the point
- Because it is tiny, most SideKick complaints are load-size and item-type: only small, delicates or a handful of items fit, and overfilling it stops it cleaning or draining properly. It is not a fault when it cannot handle a normal load — that is the main washer's job.
- Installation coupling
- It shares the same water supply and drain routing as the main unit through the pedestal, so a leak or no-fill can originate in the shared connections rather than the SideKick itself.
- Size class
- One of the smaller models in its line, which has a direct consequence: a smaller body holds a smaller battery, so its rated runtime is genuinely lower than its larger siblings. Runtime that looks poor beside a Max is usually this rather than a fault.

Exact questions
Questions that only have an answer for the LG SideKick WD300 pedestal washer
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My LG SideKick won't clean or drain a full load.+
The SideKick is a 1.0 cu. ft. pedestal mini-washer meant for small or delicate loads only — a handful of items, not a normal wash. Overfilling it is the usual reason it does not agitate, rinse or drain properly. Use it for the small second load it is designed for and run larger loads in the main washer above it. If it genuinely will not fill or drain when lightly loaded, check its own water and drain connections in the pedestal.
