Greetings, Wise Ones,

The upper drawer on this unit gives a U3 fault code several minutes into the cycle, on the third wash. I've had the local appliance guy over in an attempt to repair the problem. He blew out the drain hose with compressed air and even changed out the motor/impeller assembly but no joy. He's not sure what to do next and I, of course, have no clue. So, here I am. I would be most grateful for pearls of wisdom from the Masters of Appliantology.

Thanks,

Bill

This is an emerging issue that Fisher Paykel engineers are studying. They believe the valve changes pressure and the dishdrawer's control board thinks its going to flood. The fix is to replace the fill valve, PN 526850. Order new clamps, too, PNs525466.

Hokay, heres what ya gotta do....First have the unit turned off. Then open up the drawer thats givin you trubbel.
The badge ought to be lit.
Now simultaneously press those static touch pads on each end of those led status lites (the ones on the drawer top?) (Cycle Select, and Eco-sensor pads)
Hold them for about 5 seconds.
Now If you have a metal front machine, the badge display will either show HP or LP. Assuming you have normal water pressure here like about 50 - 70 psi you want ta select the HP setting.
Do that by pressing the start button till you get what you want, then press power off to lock the setting in.
If you have an integrated model (you know.... matching your fancy smancy kitchen cabinets?)
Listen for a Hi or Low beep instead of looking for a display in the badge window.

this applies to 602's only. The 603's got smart and figgered out the difference all by themselves

I have a lot of trouble with reoccuring U3 fault on the dd601v2.  The controller seem to be over sensitive and it will start beeping and flashing even when unloading, which can lead to the water pressure setting changing.  I have removed the controller on the affected drawer, given the exposed keypad p.c.b a wipe with a cloth, as well as the under side of the drawer were it fits in, as reside can build up in this area.  This sometimes works, but othertimes only way is to replace the controller

Just when I was ready to give up and call the repair technician for an ongoing U3 code with the top dishdrawer, I came across this site.  Resetting the top drawer to HP rather than the LP setting was able to resolve the error code.  Have had the dishwasher since 8/01 and this is the second error code experience.  First was within 6 months of install, F1, and required technician support and a hefty bill. I am thrilled to have fixed this problem on my own!  Thank you Bob.

Brilliant; got a U3 code and followed your instructions with instant fix; unit is about 3 years old and been good so far.  Your fix even works here "downunder":)

The problem you describe is very similar to what I have been experiencing. How do I get to the controller? Please keep me from becoming overly violent with my appliance, oh wise one.

Have you tried Bob Sankie's advice on resetting the pressure setting first?

Yes, to no avail. In fact, the touchpad settings jump on their own even while loading the drawer, often resulting on a several settings displaying an amber light while the main oval front display shows a red "HP". Other times, we can't get it to change the setting, no matter how hard we press on any of the dimples on the drawer. I've discovered, however, that if I wipe the controls with a dishrag, we can get them to be responsive again. Too responsive, that is. So much so, that unless I close the drawer very gently, the setting jumps to the next one (normal -> fast). When washing on "normal" (either green or reed), we usually get a "U3" code just a few minutes into the cycle.

I'm guessing I'll have to change some sensor or some component related to the control panel (which I actually was able to figure out how to access), but would deeply appreciate some advice as to which is the most likely culprit.

muchas gracias.... Wait. Wrong language.

Sorry, I can't help this time.  You are in the USA (I assume).  We have a differnt electrical system, and therefore different control boards.  I suggest email Samurai:samurai:, he knows all!!;)

You are brilliant!  Worked for me, too.  Have had unit since 2000 with this happening about 2 years ago.  I looked in manual this time and didn't see the fix until I looked again AFTER I follwed your advice.  Thanks so much for taking the time to save us all money.

I know one family in San Diego and I'm sending your name to them now.

"Bob Sankie rocks!"  Tried his solution and it worked.  Takes 1 minute.  :cool:

I wonder if I triggered the problem by simultaneously running the water sprinkling system and the dishwasher causing changes in water pressure?  Have an older house with old pipes.

Worked for me too!  I wonder if I should change my other drawer to HP or just wait until it fails . . . also I wonder if I'm really masking another problem?
