LD on a Whirlpool washer stands for "Long Drain" — the machine tried to pump the water out and it didn't leave fast enough, so it flags LD and stalls with water in the tub. It's the same family as the F21 code, and the most common cause is something you can clear yourself. Here's the order a tech works it.
The overwhelming cause of LD. Coins, lint, hairpins, and small items collect in the filter behind the small panel on the lower front and block the drain.
Check it: Open the lower-front panel, put down towels, unthread the round filter slowly (water will come out — drain in stages), and clean everything out. Run a rinse+spin to confirm LD is gone.
A drain hose kinked behind the washer, or pushed too far down the standpipe, stops the water and triggers LD.
Check it: Pull the washer out gently, straighten kinks, and make sure the hose only goes a few inches into the standpipe.
If the wall standpipe is partially clogged, water backs up and the washer reads a failed drain.
Check it: Remove the hose from the standpipe and pour water in — if it backs up, the house drain needs clearing.
If the filter and hoses are clear but LD persists, the drain pump has likely failed.
Check it: Listen for the pump during the drain step — no sound with a clean filter points at the pump, a straightforward tech replacement.
Almost always repair — most LD codes clear for free by cleaning the coin trap, and even a failed drain pump is an affordable part plus flat labor.

Clean the drain-pump filter (coin trap) behind the small panel on the lower front — towels ready, drain the water slowly, clear everything caught inside — then check the drain hose for kinks. That fixes the large majority of LD codes.
They're the same family — both are "long drain" faults meaning water isn't pumping out in time. The fix is identical: clean the coin trap and check the drain hose and pump.
Often nothing (a coin-trap clean) or an affordable drain pump if it failed. Your $50 Quick Check credits toward the repair.
