LG LDTS5552 Top Control Dishwasher

The LDTS5552 is a recent top-control dishwasher with QuadWash and Dynamic Dry, so its faults cluster around the drying vent, the door latch, and the fill valve. Below are the covered models, the common problems, the codes, the parts, and a repair-or-replace line.

Models covered#

Two variants built from 2022 to 2024 share one platform:

Common problems for this model#

Error codes#

• Error tE — door latch not detected
• Error IE — slow or no fill
• Error AE — leak / aqua sensor
• Error PF — power failure

For an unlisted code, unplug or trip the breaker for 60 seconds and restore power; a returning code needs a diagnosis.

Recall status#

There are no active recalls on the LG LDTS5552 series as of 2026-05-28. Check your model against the Consumer Product Safety Commission list at cpsc.gov periodically.

Repair or replace?#

This is a newer model, so repairs are very cost-effective given its age. The rule: under 10 years old with a fix below 50% of a comparable new dishwasher, repair. After 10 years, weigh recent costs — once repairs over the last 2-3 years exceed 40% of replacement, replace. The Dynamic Dry vent fan is the likeliest first repair you will see.

Maintenance#

Most LDTS5552 faults are preventable. Keep the rinse-aid reservoir filled, since Dynamic Dry depends on it to shed moisture, and check the door-latch alignment after installation so the tE error never appears. Clean the water-inlet filter screen once a year to keep fills quick, and avoid loading heavy items on the third rack, which is what binds the adjuster.

FAQ#

What is Dynamic Dry, and why are my dishes still wet?#

Dynamic Dry opens a vent at the end of the cycle to release moist air, drying with less energy than a heated element. If dishes stay wet, top up the rinse aid first (Dynamic Dry relies on it), then check the vent fan assembly (ABA72913207), and give it 5 minutes after the cycle before unloading.

How do I clear a tE error?#

tE means the dishwasher does not sense the door as fully closed. Confirm the door sits flush against the tub, the latch strike lines up with the hook, and no food is blocking the latch; if alignment is correct, the latch assembly (ADF73448901) is the likely replacement.

The dishwasher fills slowly and shows IE — what now?#

An IE code points to a slow fill, usually a partly closed supply valve or a clogged inlet screen before the inlet valve (5221DD1001F). Confirm the household shutoff is fully open and clean the screen; if the fill is still slow, the valve is the next step.
