LG washing machine, PE error code, understanding the faults with the pressure switch system

When confronted with an LG washing machine displaying a PE error code, *it's crucial to comprehend the basic function of the pressure switch and its system. The washing machine's base houses a pressure chamber, connected to a tube that extends to the washer pressure switch. This switch then conveys a frequency reading of the water level within the drum to the circuit board or washing machine programme.
As a result, the programme can Control the water level in the machine, enabling it to turn water valves on and off at the necessary points during the wash cycle🔧

Dear Paul, thanks for the reply. I have changed the pump and this has definitely fixed the problem. It was showing the OE fault code but the reason I believed it was not the pump was that it was an intermittent problem, that is it was pumping at times during the cycle but usually not before the final spin thus complicating the diagnosis. I took the old pump out and connected it to the mains and repeatedly turned it on and off. And bingo! at times it turned round and sometimes it dit not. Then I saw that the spindle (connecting the motor and the impellor) was loose in the housing. When the pump turned I could tell that it was "rattling" and not turning smoothly. A new pump has solved it! Cheers

Dear Paul, your videos have given me much insight into my LG washing machine but it is still just driving me nuts. Giving the OE error always at the beginning of the final centrifuge cycle, that is always 15 minutes before the end of the cycles. I have tried everything, stripped it down, checked all the hoses, they are clear. Taken the pump off which pumps fine until it gets to 15 minutes before the end of the wash. Checked the level sensor tube, can blow through it. I have let the machine run with vinegar mixture in an attempt to clean it. After dismantling it seemed cured but now (4 weeks later) has the same symptoms. What on earth can I try next. Any advice would be much appreciated. Cheers, The Netherlands

If the machine is stopping when it's full of water and you know the impeller is turning freely then all I can think is the pump
