I've just solved the same problem on my 2120. It started when the pump motor bearing failed and continued after I'd replaced the bearing. According to my handbook the E1 fault is theoretically a water leak but practically it is that the pump is not delivering enough water. In this case the failed bearing had allowed the shaft to wobble about and damage either the rotor or the inside of the pump (it's sealed so you can't strip it). Solution was to replace the pump.

I fixed the Error E1, 3 days ago in my dishwasher... actualy, it was easy: with the machine stopped, I pull the drain hose , and suddenly i felt a small squirt of water to my arm. The hose had two small ranks (crarcks). i just used insulation tape for plumbing, witn many turrns (a white one, whose name I do not remember), and then use another insulating tape with glue on one side, with many turns likewise. Solved! The error E1 disapear , and used the machine for 3 times now, without errors and dishwasher "stopings" . Hope my experience help you ... good luck. Rui Martins, Portugal,

LG dishwasher LD-2120WHU I get the


This happens to my LG dishwasher every 6 months or so. It also makes a groaning sound as if the system is starved for water. The resolve the problem by removing the dishwasher and laying it over on it's right side. I then remove the two plastic assemblies that are on the left side and I remove them from the dishwasher (you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall) and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. Until you have time to do this I recommend putting a few quarts of hot water into your dishwasher once you start to hear the groaning problem. This solution should be very easy for anyone who is comfortable doing their own oil change. Oh, and turn off the power supply first.

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.
