Steps to Clear the Error Code E1 on an LG Dishwasher

In LG dishwashers, the E1 error code indicates that the running pump is not getting the back pressure. Most likely, the drain hose is leaking. There are a number of steps, which can help you clear the error and get the dishwasher back to work.

If you see E1 or AE on the display, most likely, it is because:

  1. The dishwasher was not installed properly.
  2. The dispenser is overloaded with detergent, or a wrong type of it is used.
  3. There is a leak in the dishwasher door.
  4. Dishes are not properly positioned in the dishwasher.
  5. The sump motor is bad.
  6. The float is bad.
  7. The sump assembly is leaking.

Check the troubleshooting guide, locate the parts and see ways of clearing the E1 error:

Install the drain hose properly

Is the hose positioned lower than the base?

  • If the drain hose outlet is placed below the base, the dishwasher may drain too early. This can result in the appearance off the E1 error code.
  • Please, make sure that the end of the hose is located at least 10 inches from the bottom.
  • This will prevent premature syphoning of water from the tub.
  • Make sure the drain hose is not damaged.
  • If it is, replace it.

Use detergents properly

  • Using the wrong type of detergent can produce excess suds.
  • Use detergent types specified in the instruction manual only.
  • Failure to use the right type of detergent can lead to excess suds.
  • Excess suds will not let the machine to wash the dishes properly.
  • E1 error code appears when there is too much suds.
  • Make sure that the detergent is intended for automatic dishwashers.

Make sure the door is not leaking

  • When the machine is working, check the door for drops of water seeping through.
  • Check the door seal for damage.
  • If the door seal is damaged, replace it.

Load dishes properly

Check the dishes after loading: are there oversized pans and pots?

  • The positioning of large items can influence the distribution of water around the tub and lead to excess water.
  • The system can detect excess water as a sign of flood and produce errors.
  • Place all large items correctly as shown in the instruction manual.
  • Make sure they do not hold water.

Check the sump and float assemblies: if there are faulty parts, replace them.
