I am not sure something inspection or service,may you have to take to dealer.

I would google for a manual or an error code.

Well, no, actually. P2 is an error related to the evaporator temperature probe. I would start with the electrical connections, the bond between the probe and the evaporator, and the evaporator fan.

Does your remote have batteries? If yes change them. Somewhere on the unit there should be a selector switch, put it into test and manually lower the thermostat setting

p2 would mean your rinse thermistor is open or shorted. its located on top near the the right side, after the vac. brkr. part# is 328994. remove old, istall new . dont forget to vote,hope this helps , monomoy

To determine if your pump works, before attempting access from the bottom of the top drawer or from the bottom of lower drawer: You can manually pump the water out by doing the following:
1- Press the Power button to turn off the display.
2- Press the Lock button and then the start button the same tim. Hold them until the display showing up.
3- If the display is not clear with all the characters, press power button to see clear the display.
4- The first display is bL, then Er,Ld..dd, FU, P1, P2...by pressing the Start button to go by the sequence until P2 (drain). If you miss, be patient to continue press and release the start button to get back to P2.
5 When is is at P2, press Lock button to tun on the drain. When you hear the water flowing to the drain, you could pull the top drain to see how the water is draining.
6- When the water is out, press the lock button again to stop it.
7-When it is done, press the Power button to get out of manual mode.

If this is working, then your water is there because you are running the bottom and your air gap allow back flow to the top drawer and or you are running the top and your air gap allows a back flow to the bottom drawer.
Please let me know if this is not the case.

Put the files on the root of the P2's folder. Unplug the P2. Leave it off for 2 mins, and power up.
Now, if this does not work, you probably need a config.dat file which you copy with the 2 firmware files onto your P2.

Open notepad
write:

YP-P2
XX XX UMS                              
     
          
Replace XX XX with the 2 letters in front of your P2's firmware (Settings>System>about). Example: EU EU UMS

and save as config.dat (remember all files)
