Some of the other things to check out include:
- Ensuring that there is no moisture flowing into the casing outside. This can happen if you accidentally spill something, or when a pipe breaks out.
- The drain hose is not joined properly; thus, water from the sink tends to get inside.
If the above issues are not causing the problem and the LE error is still persistent, then you may want to check the pan and ensure that it is not full. To do this:
- Unplug the unit
- Remove the machine’s sidewall.
- Check to see if there is water inside. Note that this may be difficult to tell because the dishwasher tends to drain water faster when it is unplugged, and the door is shut off.
- Remove any excess water by tilting the casing slightly. This should click the float in place.
- Let the machine dry before restarting it. Although the real leak may not be fixed, the machine will restart
- When the drip pan is dry, move the float sensor. It is possible that the contact stuck on it because of getting into constant contact with a soapy and greasy environment.
Triggers of the LE Error and possible Fixes
If the above fixes fail to work or eliminate the LE error, you should consider checking out other issues, including the leak. It would also be great if you knew the exact point where the leak happens, and at what point it occurs. Inspect the machine when it is powered off, and the door closed. Some of the potential issues could be as follows.
Failed Temperature Sensor
A failed temperature sensor may interfere with the washer’s functioning and cause the LE error to appear on the screen. Several factors, including also trigger the failed sensor.
- Failed sensor. This is where the sensor does not send the correct readings to the control board, causing it to register that the water in the washer is too hot when it is not.
- A dirty sensor that requires cleaning could be causing the problem. Sometimes there is a buildup of calcium around the sensor, which causes it to send wrong signals to the control board. This may require cleaning, and in worse cases, the temperature sensor (View on Amazon), may need replacing. Make sure that you are picking the correct model for your machine.
Water Fails to Drain Properly
The LE error code also pops up on the washer whenever the machine fails to drain water properly. In most cases, the issue is caused by:
- A clogged drain hose. This could be a full or partial blockage of the drain pump side or under sink drain hose.
- A jammed drain pump impeller causes the motor not to spin. You are likely to hear humming sounds from the pump, but you will notice that it is not working.
- A burnt drain pump motor
- Issues with water intake. This can happen in two ways. The first is where the water inlet valve has a mechanical or electric malfunction such that the valve coils are burnt, or in a mechanical case, calcium buildup causes clogging on the solenoid valve. In the second instance, the water tap located below the sink could be switched off.
Darin Pump Leaks
You can tell that the drain pump is out of order when it leaks water when washing. Check to see if the gaskets are worn out and replace them. If the gaskets are perfect, then the pump itself may have issues. This may not be something you can diagnose or fix on your own. Call in a professional to determine the next move.
Mechanical damages to the tank can also trigger the LE error code to display in the machine. Sometimes the damages could be due to factory defects or misuse by the owner whenever they violate usage rules. The first thing you ought to do is to carry out and inspect and physically locate the leaks. Disassemble the dishwasher and check for moisture traces inside. Once you find the defective parts, replace them with a new one.
Drain and Filter Issues
The drain could have issues because of either pollution or the wrong installation. Whenever a clog causes the issue, then the error will pop. In addition to this, water is likely to flow out through the gaps. You can fix this by unscrewing the filters and or replacing them in case the damage is severe.
Check the installation. The issue could be occurring because you failed to fix it properly after cleaning it the last time. Have it fixed properly. However, check to see that the thread is not torn since this will hinder proper installation, thus the filter element should be replaced.
Clogged or Cracked Dispenser
If the error appears whenever water begins to enter the chamber, then there is a cracked or clogged dispenser. Start by checking the detergent section to see if there are any residues on the wall or broken in any way. In case of breakages, the dispenser should be replaced immediately. Remove the powder residue from the walls if present.
Worn Out Chamber Gaskets
In the long run, the rubber gaskets tend to wear out, more so those located on the lower side. This causes an accumulation of puddles under the machine. If you suspect that the gaskets are loose, strengthen them. However, if they are cracked and hardened, then replacement is the best option. This may need the entire dishwasher to be disassembled. Hire an expert to do this.
