After starting any program, first pumps out the water, then starts to fill it up, in 10-15 sec an error message comes that means water overflow. Filter was checked, removed - it is not clogged. Water can flow away, it pumps out. So there is no visible sign of water overflow.
Can be also only full of dirt in the hose as in this video https://www.youtube.com/watch?v=9dbrAbLqVyE or one of microswitchs not working properly, or broken cable lines leading to computer unit on the front doors
SOURCE: F4 Fault indication
F4 is a water inlet fault. It doesn't make sense if you have this fault indication with water flowing into the unit. Does the dishwasher drain properly? Usual suspects for an F4 indication would be a clogged inlet line, water supply turned off, bad fill valve, or a control board failure. Let me know if this helps, or give me a little more information on what you have done to correct so far.

you have a wash pump problem. can be 1 of 3 things. most likely something is caught in the pump impelor if not the wash pump motor may be faulty or ceized or it could be the capacitor for the wash pump motor is faulty. you can try removing the wash pump yourself and check the impelor if it spins freely then you will have a motor problem.
hope this helped

Yep, impeller motor problem.... mines done it twice now. Absolute piece of **** dishwasher. I HATE IT!
Hi,
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor.
else you need to REPLACE THE PCB POWER CONTROL BOARD
Good Luck!!!
