If the LG LDP6810 does not fill, look for IE on the display: LG's manual lists it as a water inlet problem and names a clogged, kinked or frozen water inlet hose and the water supply as the things to check. Confirm the supply valve under the sink is open, follow the inlet hose for kinks, and check that the water pressure is between 20 and 80 psi. FE is the opposite fault, excessive water supplied, and that one is a call to LG.
Differential
Likely causes of “LG dishwasher will not fill with water”, and how to tell them apart
- 1
The water supply valve is closed or partly closed
What separates it The dishwasher starts, hums and IE appears with no water in the tub
How to confirm Open the valve under the sink fully and try the cycle again
- 2
A kinked, clogged or frozen inlet hose
What separates it IE shows and the hose looks pinched behind the dishwasher or is stiff with cold
How to confirm Follow the hose from the valve to the dishwasher for kinks and check for frost
- 3
Water pressure outside 20 to 80 psi
What separates it Filling is slow or very noisy, or no water arrives
How to confirm Check the household pressure; LG says the range is 20 to 80 psi (140 to 550 kPa)
- 4
The door did not latch so the cycle never started filling
What separates it The LED flashes, the dishwasher chimes and no cycle begins
How to confirm Close the door within four seconds of pressing Start and check the door seats evenly
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether IE or FE is on the display
- Whether the supply valve is fully open and other taps in the house run normally
- Whether the inlet hose is new, kinked or in a cold space
Try in this order
0 of 5 completedCheck the supply valve
ReversibleOpen the dishwasher shutoff valve under the sink fully. A partly closed valve is the easiest cause to miss and gives IE.
Follow the inlet hose
ReversiblePull the toe kick or reach behind the dishwasher if you can, and check the hose from the valve for a kink, crush or frost. Do not use an old hose again if you replace it.
Check the pressure and temperature
ReversibleLG needs 20 to 80 psi and a hot supply of 120 to 149 F. A pressure gauge on an outdoor spigot or nearby fitting is the quickest way to read the household pressure.
Restart the cycle correctly
ReversibleClose the door, press Start, and if the LED flashes with a chime, open the door and start again. On top controls press Start and close the door within four seconds.
Read the code before repeating
ReversibleIf IE appears again, note it and stop repeating cycles. LG says to check the hose and the supply, and to call LG if it persists.
Model-specific
What is true of this model and not of its siblings
- Water numbers from the manual
- 20 to 80 psi (140 to 550 kPa) pressure, 120 to 149 F (49 to 65 C) inlet temperature, 3/8 in copper or braided stainless supply line, and a new inlet hose at installation; an inlet hose kit is listed as part AEM75698902.

Stop boundary
When this stops being a self-service repair
- !If IE returns with the valve open and a clear hose, call LG customer service
- !If FE (excessive water) shows, turn off the water supply and call LG at 1-800-243-0000 in the U.S.
- !If the household pressure is out of range, call a plumber about a regulator or supply problem

Exact questions
Common questions
What water pressure does the dishwasher need?+
20 to 80 psi (140 to 550 kPa), according to the specification table.
What water temperature is best?+
A hot supply of 120 to 149 F (49 to 65 C). LG says this range gives the best washing results and the shortest cycle time.
Why does the dishwasher chime and not start?+
LG says the door must be closed within four seconds of pressing Start on top-control models, or the LED flashes, a tone sounds and the cycle does not begin.
Can I reuse the old water hose?+
No. LG says use a new hose, because an old one could leak or burst.
Is a whistling sound while filling normal?+
Yes. LG says a whistling noise as water is drawn in is normal, and if pressure is too high it is louder.
Does the dishwasher turn off by itself?+
Yes. It turns itself off after four minutes of inactivity if paused or if no cycle is started.
