5859DD9001A Genuine Wash Pump Assembly for LG Dishwashers, Circulation Pump Motor, Mounting Bracket 4980ED4001A Not Included

Genuine LG wash pump assembly 5859DD9001A is the pump that drives water through the spray arms in LG dishwashers. One thing to check before ordering: this pump no longer comes with the mounting bracket 4980ED4001A. Older models need that bracket, so if your existing pump sits in one and it's damaged, order the bracket as well. No model list is on file, so match the code on your old pump or send your model number through the parts enquiry form.

LG dishwasher not washing properly?

During the wash, the pump draws water from the sump and pushes it under pressure up to the spray arms. When it fails, dishes come out dirty or gritty, the spray arms barely turn, and you may hear humming, grinding or no pump noise at all while the dishwasher fills and sits. Some machines show an error and stop the cycle. Before replacing the pump, clean the filters and check the spray arm holes, as blockages cause similar symptoms, and look for broken glass jammed in the impeller.

Questions about this part

Do I need the 4980ED4001A bracket?

Only if your dishwasher is an older model that uses it. The current 5859DD9001A pump is supplied without the bracket. If your old pump is mounted in a bracket, reuse it if it's sound or order 4980ED4001A separately.
