LDT5678ST
LG LDT5678ST QuadWash Dishwasher Service
Most common issues on this model
- Control board and panel response
- Spray arm spin and nozzle blockage
- Drain pump and filter screen
- Water inlet valve and fill time
- Rack roller and track wear
The LDT5678ST is an older LG top control dishwasher with QuadWash and electronic cycle control. LG has discontinued it, and it came in more than one finish. It is still found under counters in many homes, so we see calls on it from owners who prefer to keep a machine that still works.
With electronic control on an older unit, a stalled cycle or a dim panel sends us to the door latch and the power feed first, and then the board. For cleaning complaints we follow the wash path: filter, arms, fill, and drain. Rack rollers and tracks come last, but they matter, because a worn roller can let a dish block an arm.
We confirm the model and serial from the label before ordering anything, and we tell you honestly if a repair is not worth the cost. A written price comes before work, and our repairs carry a 30-day workmanship warranty.

Is it worth repairing an LDT5678ST?
It depends on the cause and on parts availability. We give a written price after diagnosis so you can compare it with replacement before we proceed.
Why does my dishwasher stop in the middle of a cycle?
A door latch that loses contact, a power dip, or a board problem can stop a cycle. We check the latch and supply first, then test the board.
Do finishes affect parts?
They can change the last letters of the model number, so we read the complete model from the label before ordering any part. That keeps us from bringing a part that does not fit your version.
