LG SideKick WD300CV pedestal washer does not clean clothes well

LG SideKick WD300CV pedestal washer does not clean clothes well: poor cleaning is usually resolved by load size, cycle, soil level, detergent, temperature and water flow before parts replacement. Scoped to WD300C*, WD300G*.

An LG SideKick that does not seem to clean the clothes is almost always being asked to do more than its size allows. The SideKick is a 1.0 cubic foot pedestal mini-washer, model WD300CV, sold to sit under a compatible LG front-load washer and take a small second load, such as delicates, a few items or a quick wash of gym clothes. It is not a second full-size washer, and loading it like one is the main reason clothes come out dirty.

The checks in more detail

A drum packed with items cannot tumble, so soap and water do not reach the fabric, and heavy items stop the drum moving. Start by halving the load. Put in only a handful of items, leaving space for them to move, and wash again. Use a high-efficiency detergent in the small dose suited to a mini load; a full measure of detergent in a tiny drum produces suds that cushion the clothes and rinse poorly.

Choose a cycle that matches the load: a normal cycle for lightly soiled clothes, a stronger setting for greater soil, and warm water if the label allows. Pretreat stains, since a short, gentle machine does less mechanical work. Next, check the machine. Make sure the water taps that serve the SideKick are open; it has its own water connection, and a weak fill leaves too little water to wash.

Look at the detergent drawer for caked detergent that stops the dose reaching the drum, and clean the drain filter so the machine can drain and rinse. Because the SideKick shares routing with the main washer through the pedestal, a restricted hose can reduce water to it. If the washer fills, tumbles and drains normally with a small load, then it works; if it fails to fill or agitate, note any error code and contact LG with the model number WD300CV. For regular full-size laundry, use the main washer above.
