E1 Error on LG Dishwasher (LD-2040WH)

Hi All

 

We are having a problem with our LG Dishwasher. The machine is washing for about half an hour and then will stop and report an E1 error. According to the user manual this means "Water leakage in Hose connection" or "Water is leaked by damages". We have checked the diswasher's water connections and can't see any water leaking out. We have also cleaned the filers and checked the spray arms but that has not made any diffrence. Any suggestions what this error means and what we can try to resolve it would be appreciated.

    I'm having the same problem and would appreciate any advice. My guess is I should just buy a cheapter tried and true Whirlpool or GE.

    I have the same dishwasher modem and after full investigation for water leaks etc. could not find anything wrong. Sometimes by selecting the shortest washing period all seems fine, but when selecting it again it comes up with the E1 code haldway through the cycle.

Maybe the blockage is somewhere else. How about removing all the trays from the dishwasher, in other words, empty it from all racks and dishes and try it again

The IE or 1E error or fault code indicates that the washer is not filling with water. Check to be sure the water supply valves are open. Also, check to be sure the water supply hoses aren't kinked or clogged. Next, remove the hoses from the washing machine and run water into a bucket to test the pressure and flow of the water. If all of these check out and you have good water pressure and flow to the machine, you should replace the water inlet valve.

LG dishwasher error code E1


E1 is a code that the dishwasher displays after detecting a leak. There is a sensor on the pan at the very bottom of the unit. Take the bottom front panel off, look under the unit at the hose coming off the pump and your fill line to be sure no water is dripping. Run the unit in a wash cycle while doing this if possible.

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.
