LG dishwasher not draining is a known issue affecting LDP6810 series. Our technicians specialize in LG-specific diagnostics and repair.
LG dishwasher not draining is typically caused by clogged drain hose or failed drain pump. LG-specific factor: drain hose loop too low — water siphons back into tub after drain cycle. Repair costs $100-$250 with free diagnostic and 90-day warranty.
Drain hose loop too low — water siphons back into tub after drain cycle
Check valve buildup from food debris and mineral deposits
Drain pump motor shaft seal failure causing internal leak and corrosion
Fine filter mesh clog preventing water from reaching drain pump inlet
Control board drain cycle too short — firmware issue on early production runs
Other LG models may also be affected. Book a free diagnostic for confirmation.
Seeing one of these codes? It likely indicates not draining.
Bay Area LG dishwasher drain failures often trace to improper installation in remodeled Victorian kitchens — countertop replacements sometimes shift the dishwasher position, creating a drain hose sag below the air gap connection. Local plumbing code requires an air gap but older installations may have only a high loop that degrades over time.
Remove lower spray arm, filter assembly, and sump cover — inspect drain well for food debris and mineral scale accumulation
Check drain hose routing under sink: must connect through air gap or maintain high loop above drain line center
Test drain pump: run LG test cycle (press Power, then Rinse + Spray 3 times within 3 seconds) — pump should engage within 10 seconds
Inspect check valve (rubber flap at drain outlet) — should open freely when pushed and seal flat when released; replace if calcified
The technician removes the filter and sump assembly to access the drain system. Mineral buildup on the check valve is the most common finding — the valve is cleaned or replaced and the drain path flushed. If the drain pump motor has failed, replacing it requires disconnecting the water supply and pulling the unit forward to access the underside. The technician also corrects any drain hose routing deficiencies.

“My exprience with Easy Bear was absolutely superior from the beginning. I had a Subzero decide to quit. Daniel assessed the issue immediately, ordered the required new " motherboard" and had it installed within three days. My prior replacement of said part took 5 months during Covid. Daniel is smart, professional, clearly knows his trade . I most definitely will use Easy Bear in the future.”

“Daniel the technician came to diagnose what's causing our washing machine water overflowing. He didn't actually have to do anything to solve the issue, because as soon as he turned it back on, it began to work properly, but explained what the probable cause was. He was sincere and clear on the matter related to the situation. I wasn't charged for his visit as I was told ahead of time. Stanislav was also cordial arranging for all of the process. I will call them next time I need an appliance service without hesitation.”
