LG Dishwasher Leaking from the Bottom? Here's How to Fix It

Is your LG dishwasher leaking from the bottom? This is very annoying, especially when you do not know if the water is coming from the door or underneath the machine.

Don't worry. I have seen this problem many times, and it is often caused by something simple that you can check yourself.

I will explain the safe checks first, then show you when the dishwasher needs a technician.

How to Stop an LG Dishwasher from Leaking

To fix an LG dishwasher leaking from the bottom, check for excess suds, a dirty door seal, blocked spray arms, and loose water or drain hoses.

Before starting, switch off the breaker and close the water valve. If your dishwasher is under warranty, do not remove its lower panel.

Check for Excess Foam

Too much detergent can push foam through the bottom of the door. Regular washing-up liquid will make the problem much worse.

Remove the foam and run a rinse with no detergent. Use only dishwasher detergent next time. Too many suds is a common cause and are easy to fix.

Clean the Door Seal

Wipe the rubber seal and the edge of the tub. Look closely at the lower corners because food often collects there.

Push a loose seal back into its channel. Replace it if it is cut, hard, or flat. There may be small amount of dirt that is enough to let water pass.

Make Sure the Spray Arms Turn

Pull out the racks and turn each spray arm by hand. Move tall dishes and clear blocked holes with a toothpick.

A split arm can aim water at the door, so replace it if you find a crack. These check may also improve poor washing results.

Inspect the Hoses

Check the supply and drain connections below the sink with a dry paper towel. Tighten a loose clamp after the water is off, and replace a hose that is split or swollen.

If water stays in the tub as well, follow our guide for an LG dishwasher that is not draining. Dry connections make an internal leak or AE warning more likely.

Get an AE Warning or Lower Leak Checked

An AE warning can appear when the dishwasher finds moisture in its base. Read our guide about the LG dishwasher AE error for more details.

Do not keep resetting the dishwasher to clear the warning. The pump, inlet part, or an internal hose may needs repair, so leave this work to a technician.

Conclusion

Work through the easy checks before paying for a repair. These are the five solutions:

• Remove excess foam
• Clean and inspect the door seal
• Check the spray arms
• Inspect the supply and drain hoses
• Get an AE warning or lower leak checked

Keep the dishwasher off if water comes back or reaches any electrical part.
