How do you replace the impeller on a LD-2040 dishwasher?

check and see if there is a drain out problem

I traced the fault to one resistor on the controller board and replaced it for R0.10. The original quote to repair was R1480.00! So I saved myself a handsome amount, no thanks to LG!

Hi

E1 is a leakage error in your LG dishwasher; it is usually displayed either due to a clogged drain or due to water leakage in hose connections. If the drain pump assembly is not clogged then check the motor water seal leakage of sump assembly and also check the impeller of washing pump, if it is worn then replace the impeller. You can also make sure that the height of drain hose is not over 20". Hope this helps...please post back for further assistance.

If you've checked everything, you will need to replace the impeller possibly.


Leakage error > Conditon: Excessive RPM of washing motor happened during wash cycle due to water leakage. Possible cause: Water leakage in hose connections,water is leaked by damages. The motor water seal leakage of sump assembly. The height of drain hose connection ( sink drain hose ) is not over 20". Impeller of the washing pump is worn away.

E1 leakage error
The excessive RPM of Washing Motor happened during Wash cycle due to water leakage.
Water leakage in Hose connections. Water is leaked by damages. The Motor Water Seal leakage of Sump assembly. The height of Drain Hose connection (sink-Drain Hose) is not over 20 . Impeller of the Washing Pump is worn away.
Replace the connections of Hose. Check the point of damages and repair or replace the related parts.
Replace the Impeller of the Washing Pump.

Just replaced wash pump unit
Thanks anyway

Hi. this may be caused be several issue that i will discus below. Kindly read over the list that will describe several issue that may be apparent. replace any parts that corresponds to the issue you are having.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Impellers in these often break, will need new pump for easy fix or you could try & replace the impeller

if you need a user manual log onto LG's website. they are avalaible as PDF files.

take care.

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.
