On the LG LDP6810 a leak has one message that matters: AE means water leakage, and LG says to turn off the water supply to the dishwasher and call LG at 1-800-243-0000 in the U.S. The dishwasher sounds an alert for 10 seconds and runs its drain pump on and off, and it powers back on by itself until the problem is fixed, so turning off the power does not stop it. Suds from the wrong detergent, a dishwasher that is not level and an old water hose are the other causes the manual names.
Differential
Likely causes of “LG dishwasher is leaking water”, and how to tell them apart
- 1
A real water leak inside the cabinet, shown by AE
What separates it An alert sounds for 10 seconds, the drain pump runs on and off and water sits in the base
How to confirm Turn off the water supply and call LG; do not keep restarting the dishwasher
- 2
Oversudsing from the wrong detergent
What separates it Foam pushes out around the door and the display shows the oversudsing message
How to confirm Use only dishwasher detergent, and run the milk residue clean-out that LG describes
- 3
A dishwasher that is not level
What separates it Water leaks at the door edge and the door does not seat evenly
How to confirm Check level with a level inside the tub; adjust the front and rear feet until they all touch the floor
- 4
An old or damaged water inlet hose or loose connection
What separates it Water pools under the inlet fitting at the supply valve or behind the toe kick
How to confirm Look for drips at the supply connection and replace an old hose with a new one; LG says never to reuse an old hose
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether AE or another message showed and whether an alert sounded
- Where the water is: at the door, under the front, at the supply valve or in the sink area
- Whether the dishwasher was recently installed, moved or fed with dish soap or a different detergent
Try in this order
0 of 5 completedTurn off the water supply
ReversibleClose the shutoff valve for the dishwasher under the sink and put towels down. LG says to do this first when an AE message shows.
Read the display
ReversibleNote whether AE, bE or another message is on. AE means water leakage; the oversudsing message can appear when foamy soil or the wrong detergent is used.
Check the detergent
ReversibleLG says to use only dishwasher detergent, since dish soap makes suds that reduce wash performance and may cause a leak. To clear a suds error, turn the dishwasher off and start a new cycle.
Clear suds residue
ReversibleLG suggests pouring about 4 to 8 oz (100 to 200 ml) of milk into a shallow bowl on the upper rack and running Auto to remove detergent residue.
Check level and the supply line
ReversiblePut a level inside the tub, side to side and front to back, and adjust the feet until they touch the floor firmly. Look at the supply hose and fitting for drips.
