In my research, the PE error relates to the fill level of the washing machine. The fill level sensor is a pressure operated device. There is a sealed air line that goes from the bottom of the tub to an air pressure sensor. As the tub fills, it compresses the air in this air pressure sensor. When the tub is filled to the level selected on the dial, the sensor stops the fill cycle.

This air line can be plugged or the sensor itself can be faulty. This air pressure sensor is usually located near the top of the tub just under the top cover. If you can locate it, disconnect the air line from the pressure sensor and blow through it - it may be blocked by lint and soap from several washing cycles. There may be a filter in this line to help prevent this blockage. But the filter may have become blocked itself.

pe error on the machine is normally the pause in action. try pressing the start /pause button again to activate the wash program

The error code "PE" stands for pressure sensor error. This is typically caused by a malfunctioning water pressure sensor switch.

All that's needed is a bootable USB Flash drive with at least 256 MB of storage capacity and a Windows Setup CD. Using the program Bart PE Builder (Freeware), you can install Windows XP on the flash drive, along with other software as needed (and as available space permits).

Here is the link of Bart PE Builder
http://69.90.47.6/mybootdisks.com/mybootdisks_com/nu2/pebuilder3110a.exe

Here is the procedure

This will help you create your very first BartPE CD. It assumes that you are using Windows XP.

Make sure that your system has about 500MB of free disk space!

Download the latest PE Builder version (self-installing package) and install it.

Start PE Builder (pebuilder.exe). When you start PE Builder for the first time it will ask if you agree with the license agreement.

Now PE Builder will ask to search for windows installation files. If you don't have your windows XP setup/installation files on your system you must insert the original Microsoft Windows XP installation/setup CD at this point.
The files you have at c:\windows are not installation files. They are your already installed files!
Click "yes" to start searching. PE Builder will now search all fixed- and CD-Rom drives for Windows installation files. This will take some time. When more than one valid location is found, a dialog will appear where you can select which location you want to use.

At the main PE Builder dialog, select the "Burn to CD/DVD" option. When you are using an erasable medium, make sure that the "AutoErase RW" option is enabled. The "burn using" option should be set to "StarBurn". Select your CD writer device from the Device list.

Hit the "build" button. PE Builder will now ask you to create a BartPE directory, answer with "yes".

The license for your Microsoft Windows XP product is shown. Read it and agree to it to continue.

PE Builder will now start building BartPE. This will take a few minutes.
You will see a lot of files getting copied and/or decompressed, the ISO image build and the data recorded to your CD/DVD writer.
If the data verify was correct and there where no errors reported you can boot the CD/DVD!

After that set your PC BIOS to boot from USB,then restart.
That's it.

do you know which sensor?? i have the same problem

1. Put the cd with xp on it in the cd rom
   
2. plug your pen drive into your computer
   
3. open "my computer"
   
4. drag and drop the cd to the pen drive and it should copy the files to it.
   

Let me know how it goes.

The PE error code indicates that the machine has a water pressure sensing error. Check and clean the filters on both sides of the inlet water line. Good luck!
