Indesit w161 wiring diagram

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

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

It sounds as though the pressure chamber is blocked which is holding the pressure switch in the on position and in this situation the valves will stay energised. If you don't know where the chamber is then locate the pressure switch and follow the small bore hose from it down under the tub and it will take you to the chamber, remove it and clean it out don't just remove the hose and blow through the hole because this will only work for a few washer before it blocks again

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

LE means washing machine electronic controller has detected an overfill situation
* check for over foaming or over soaping
*check the air chamber and pressure switch hose for blockage
*check water level sensor
*check wiring to water pressure sensor
*check connections to water level sensor
*check main electronic controller

Ok the machine needs to be drained. Then switch the machine on again. The door should open.

Could try pressure switch/ clean the pipe feeding it check for hole in it causing air leak and pressure drop, make fill valve overfill

Could be but think more of an overfill fault cased by a blockage @ the pressure switch this controls the level of water in the drum shutting off fill valves. The pressure switch or air switch operates at 3 psi it is round with wiring onto it and has a tube connected to it ....make sure the Tube and chamber tat feeds this is clear as this is common to fail the valve and result in overfill,Apart from a faulty fill valve of course, this should cut off when power is removed.....good luck

possible faulty pressure switch or a faulty drain pump

You need to clear out pressure chamber the part the at tube plugs into the chamber it will be clogged, stopping air going to pressure switch...This should cure..
