Error Code LC

Water is leaking inside the base of the dishwasher

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: LC

What This Means

Overfill occurred in the tub; Water from a leak flowed to the bottom tray; Water inlet valve leaking — foreign substance preventing valve from closing; Drain pump not operating normally; Leakage switch is dirty or damaged; Float is too high or something is holding the micro switch on; Drain hose is obstructed or kinked; Base float is damaged or too dirty; Incorrect wiring to micro switch after previous repair

What actually causes this:

A hose connection came loose, the door seal is worn, or the drain is backed up causing water to collect in the bottom tray

First Thing to Check

Turn off the dishwasher and the water supply valve under the sink immediately — look for water on the floor under or around the dishwasher
