Lg ld_12aw2 error code E1 - LG 24 in. LD-12BW5 Free-standing Dishwasher

SOURCE: E1 error on LG - LD-4120M

E1 is a common error in the LG Dishwasher range and is usually caused by the failure of the circulation pump and/or the impeller.

The motor and impeller are a complete unit.

Often what happens is the impeller breaks on the motor shaft and doesn't spin, therefore doesn't pump water.

There is a pressure sensor which indicates the lack of pressure and shuts the machine down with the E1 error being displayed.

The lack of pressure can also be from a water leak (as the owners manual suggests) also a controller PCB fault may produce an E1 error, however, the pump problem is extremely common.

Unfortunately, I have had 5 pumps die in 4 years and my dishwasher is only used about 4 times a week.

this unit has an anti flood device. if it leaks it lifts a piece of plastic in the base and hits the microswitch. try leaning the unit to one side and i would put towels down. if water comes out then try a program. hope this helps.

also check the back of the pcb and see if the plastic case is melting.

Hi there,
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor. 

else you need to REPLACE THE PCB POWER CONTROL BOARD

Good Luck!!!
