Water level sensor fault

If the water levels are low in your washing machine then you could have a sensor that is faulty . The fill sensor will communicate with the control board when the washer is full to turn off the water . The fill sensor needs to be replaced for the water levels inside of your washing machine.

I don't know if its a common failure, but its the floater which is stuck. remove all the water from the and shake it a few times. If you hear something moving in there, its fine. If not, then you need to check why.

Oh boy I hope you're in the UK cuz that is a British unit here are the error code explanations
Error 1
Washing machine door lock has failed to operate or respond
The washing machine has detected an error with the door safety lock or interlock preventing operation.
Check door is closed and latched correctly
Check wiring
Check door lock
Error 2
Water drain time out or failure
The washing machine has failed to drain the water in a reasonable time, nominally in six minutes.
Check that filter is not blocked or obstructed
Check drain hose is clear of any blockage or obstruction
Check wiring to drain pump
Check drain pump is not defective
Check level sensor or switch
Check wiring to level sensor
Error 3
Not drained in time allowed - washing machine fails to drain water
Check that filter is not blocked or obstructed
Check drain hose is clear of any blockage or obstruction
Check wiring to drain pump
Check drain pump is not defective
Check level sensor or switch
Check wiring to level sensor
Error 4
Washing machine has detected problem with the wash heater
For this error code you need to check both the water heater or element and thermistor, the washing machine is reporting a fault on the heating circuit with this fault code but it is not capable of identifying exactly where the fault actually lies.
Check water heating element
Check heater for contunuity
Check thermistor or temperature sensor
Check the thermistor resistance
Check wiring to water heating element
Check connections to water heating element and temperature sensor
Error 5
Not drained in time allowed - washing machine fails to drain water
Check water supply is on, clear and not frozen
Check the air chamber and pressure sensor hose for blockages
Check water inlet valve
Check wiring to water inlet valve
Check connections to water inlet valve
Check the main control PCB
Error 6
Motor heat protector error or failure
The washing machine has detected an error on the washing machine's main drive motor circuit in relation to teh overheat protector within the motor itself.
Check motor connector block
Check motor carbon brushes where fitted
Check wiring
Check tacho connections
Check motor
Error 7
Motor error or failure
The washing machine has detected an error on the washing machine's main drive motor circuit but, like other errors cannot pimpoint he exact location or nature of the fault.
Check motor connector block
Check motor carbon brushes where fitted
Check wiring
Check tacho connections
Check motor
Error 8
Washing machine has detected an overfill situation
This error code can be caused by overfoaming which is a result of overloading (see this article) or by overdosing or, incorrect detergent as the pressure sensor will falsely read that there is too much water in the washing machine.
Also check the pressure sensor and that the machine has not actually overfilled with water.
Check for overfoaming or over soaping
Check the air chamber and the pressure switch hose
Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller
UNb
Washing machine has detected an out of balance situation
This error code is caused by an imbalanced of incorrect load in the washing machine
Check for overfoaming or over soaping
Check the air chamber and the pressure switch hose
Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller

Water level sensor fault This fault code is fairly self-explanatory and tells you that the washing machine has detected an error with the pressure sensor or pressure switch. It is rare to see this error code on LG washers.
On non-display panel models this fault code can be shown by the lights for fuzzy, heating and speedy or super, normal and hold being lit or flashing.

• Check water level sensor
• Check wiring to water pressure sensor
• Check connections to water level sensor
• Check main electronic controller

5E. This means the washing machine has a "water drain error". It's basically timed out on empty, it's tried draining out the water for 10 minutes and the water level still hasn't fallen below a specified level (or at least it thinks it hasn't). This error should be reset by pressing the Start/Pause button though if there is a fault it will need fixing or the error will just return.
A washing machine not emptying the water can have various causes as can a washing machine thinking it hasn't drained the water because it's possible that the signal telling the machine that the water has gone can sometimes not be triggered if a fault in the pressure system prevents it.
To troubleshoot this problem the first thing to check is the pump filter, which could be blocked. I have extensive advice on diagnosing pump faults here Washing machine won't drain water (stuck full of water) ' Faults on pressure system

IE - Water level sensor fault This fault code is fairly self-explanatory and tells you that the washing machine has detected an error with the pressure sensor or pressure switch

Check water level sensor

Check wiring to water pressure sensor

Check connections to water level sensor

Check main electronic controller

Defective water level sensor.

If you have water damage,call your insurance provider.

common faults include the rubber pressure hose rubbing and a hole forming causing the pressure switch not to recognise the water level. un plug the appliance, take the top off, find the pressure switch and you will see a rubber black or clear hose running from what is normally a circular item approx 2" diameter and a hose running doen to the drum, check this hose for splits or tears.

Possible fault in the water level sensor. IF the sensor does not work then the program controller will not proceed to go to the next cycle as it thinks there is no water to rinse. similar problem when it does not spin or activate the drain.

Seems that the controller thinks your machine is full of water. Water level pressure sensor may be sticky. May be blockage down air line to pressure sensor - try blowing into sensor end to clear.
(Always disconnect from power before attempting repairs).
