Question about Dishwashers

1 Answer

I have an LG dishwasher, model LDS 5811ww. The machine fills with water, then stops filling when the error code IE comes on. I have cleaned the inlet filter and the whole inside of the tub, by taking apart the sump filter. There is good water pressure filling the tank. When I turn off the power and restart any cycle, the pump will empty the tank, then begin filling the tank again...until it is stopped by the error code IE again coming on. The other thing I notice is the water level in the tub. It appears to be right up to the level of the door. Is it possible that the error code is shutting off the cycle because the fill level is too high...a switch is not shutting off the filling of the the tank? There does not seem to be a problem with the pump or the filling with water, but the transition from filling to pumping in the wash cycle. Thank you.

    Well now that I know that there is such a sensor as a water level sensor, that makes sense. What is the action you recommend to take? Is it possible to clean this sensor? Or does it need to be replaced? Thank you.

  • lizellis65 Apr 30, 2010

    What is your recommended action? Clean the water level sensor.....or does it need to be replaced (as in - not possible to clean it) ? Thank you.

  • lizellis65 Apr 30, 2010

    Well, this info and advice makes sense, so I will try to clean the water level sensor and see what happens then. Thanks.

  • lizellis65 Apr 30, 2010

    Thanks for the info and advice. I will try to clean the water level sensor, or if it looks like it needs to be replaced I will order the new part.

    I disassembled the input water tank and cleaned water level sensor appears to be functional. This did not fix the problem with error code still comes on.

    What's next?

  • lizellis65 May 05, 2010

    I cleaned water sensor level tank and swtich...that did not help.

  • lizellis65 May 05, 2010

    cleaned water input tank and water level sensor.....appears to be functional. Error code IE still comes on.

  • lizellis65 May 05, 2010

    I cleaned the water level sensor and tank as you suggested.........this did not fix the IE error code still comes on and interrupts the cycle between filling the tank with water and the wash mode starting.

    Do you think it could be the water level sensor itself? Anyway to check this? I have figure out how to work the test mode if that is of any help. Or do I need to replace something?

  • lizellis65 May 06, 2010

    water level sensor is a tank with a small float in it that activates a micro-switch as the float rises. Is testing this switch as you describe.......with an ohmeter? And what am I looking for when I use the ohmeter? What kind of numbers tell me if the switch is good or not? I am confidant I can repair this unit if I can just narrow it down to what is causing the malfunction indicated by the IE error code.

  • lizellis65 May 06, 2010

    Removed door and checked problem there. Water does fill up problem with water inlet valve. Error code IE interrupts when tank is full.........or perhaps IE comes on because the water level is getting too high, and IE shuts it off..? I have been through all the test codes and everything in this machine works when tested.......though there are different lights associated with the test than the service manual lists. But I can determine that the major functions all work. I am thinking that perhaps the problem lies with the water level sensor micro-switch. I wonder whether IE comes on if the water level in the tank gets too high?

    However, error code FE is specifically about excessive water level and it seems that error code would come on if that were happening.

    Would you suggest replacing the water level sensor microswitch? It should be fairly inexpensive part, as it is a small simple switch.

Sounds like you either have a dirty or faulty water level sensor or water temp sensor. Most likely a dirty or faulty water level sensor

    If you can find it, then you can clean it with rubbing alcohol. Sometimes cleaning works, and some times it's pitted or corroded so bad it needs to be replaced.

    I would test the water level sensor with an ohmmeter. Testing the resistance by placing a probe on each side of the sensor connections. A bad sensor or dirty/corroded sensor will cause these problems.

    You can also look at howstuffworks .com which has some good diagrams and such. Let me know if there is anything else.

    Did you
    "Measure the electric resistance of Inlet Valve. (950-1300 ω)"

    Is there any water coming in? If yes - could be flow meter. If no, could be water safety shut off valve or connecting wires.

    Also, remove the door panel and inspect the wires near the bottom of the door.
    the wires get buried in the tar like insulation causing the wires to
    break as the door is opened and closed.

    try replacing the water level switch or test it with an ohmmeter.

Hi I have an LG LD - 14AW23 dishwasher. It shows an IE error (no water) but it fills, stops and then gives the error message. What's thye problem? Many thanks, John


Error code IE on LG dishwasher means Inlet error. This error comes up when the Water Supply Tap is closed or Water Supply is shut off. If water supply is turned on then make sure that the Inlet Hose is not kinked and water Pressure is not low (should be above 10 psi). Next thing to check for is Water Inlet Valve, measure the electric resistance of Inlet Valve. (950-1300 ohms) Make sure the filter of Inlet Valve is not clogged.

Hope this helps... Please post back for further assistance.

We have an LG lds5811ww dishwasher with IE error

check for voltage at the water valve when it should be filling Try disconnecting the Water Valve outlet from the DishWasher and run the output into a bucket if all is well with the valve then remove the door panel and inspect the wires near the bottom of the door. the wires get buried in the tar like insulation causing the wires to break as the door is opened and closed.That tar like substance is one of the worst things they could of ever put into that machine causes the wires to break apart adn become brittle

Hi there, Ok, i think i'm getting close to solving this problem. I have an LG dishwasher- Model # LDS 5811ST. I have stripped it down and clean all hoses etc. It is running fine through all the cycles....

try adding some more water to the machine after it has done the fill cycle do not over fill it. if there is no change in the performance the you need to replace the main wash motor.
if there is achange the you need to change the fill valve

Does not fill with water e1 code

1E means - Water inlet problem >Condition : Not reached to the normal water level in spite of 10 minute water supply

Water supply problem. The inlet hose is kinked. The water pressure is to low (10psi) Inlet valve. The inlet water valve filter is clogged. The hall sensor. The impeller of Air guide is bound. Remedy : Check resistance of inlet valve ( 950-1300ohms) Clean valve. Check pressure. Replace the Air braker.

IE error code

IE. is inlet water valve error.

Make sure someone did not turn off the water to the washer!!!!

Remove fill hoses and check filter screens on washer and fill hoses and clean if needed.
If problem continues water valve may need to be replaced.

IE error code, machine keeps on draining

It sounds like the flood switch in the bottom of the washer is activated. check for water in the base as the machine if maybe leaking. This is a Dishwasher?

Lg LDS 5811st IE code

With an LG 5811 diswasher, when the IE error code is not caused by kinked hot water hose or blocked screen, the next step is to measure the electric resistance of the Inlet Valve. (950-1300 ohms)

Error code IE

a pressure sensitive dome is common on some units. as pressure builds, an air switch is activated.
otherwise there has to be a water contact switch.
the air switch dome can be located near the pump under the unit.
good luck
