This applies to all DD601

    This applies to all DD601 and DD603 dishdrawers.
    U3 is either one of the following:
    - Drain pump is blocked.
    - Drain hose is blocked.
    - Sprayarm or rotor not turning freely.
    - Motor electronics have failed.
    - Machine set to 'LP' on a high pressure water supply.

    Often it's just the last one, "Machine set to 'LP' on a high pressure water supply.", as this can be unintentionally changed by a user from an uncommon course of events. Sometimes, due to the technical design of the way the buttons work, if water bridges the 2 "Programme" and "Eco" buttons (inside on the top right of the tub), pressing either one, or both, (or just having your finger in the water) for longer than 5 seconds brings up a special mode that a user, in their ignorant attempts to get out of it, can erroneously change the pressure setting, subsequently causing a U3 error. It happened to me once when I was cleaning the machine, wiping around the Programme buttons.

    To change to the proper High or Low Pressure settings:
    1) LCD Display on. Hold the Programme and Eco touch switches simultaneously for 5 seconds.
    2) Machine beeps and "HP" or "LP" is displayed in the LCD.
    3) Push the Start/Pause button to toggle between them.
    4) Push the Power button when correct selection complete.

How does the front of the tub come off


Take out the two plastic pins one on each side with a nose plyer.

Slowly pull the front cover out without dropping the top panel.

Hope this helps. It would be useful to mention why you are looking at taking the front of tub out.

I have a 10 year old dishdraw (Model No DD601v2). It is displaying a fault message "F1" on the top draw display and will not start. What fault is this indicating?


Normally F1 should display in both drawers.

But this is a bit unsual. Please confirm if you are still able to operate the bottom drawer.

U3 error code


I believe U3 error on your model of dishwasher could also mean a couple of other things like either the drain hose has an obstruction (kink) or the inlet water pressure is not correct.

Hope this helps in finding out what could be the actual reason. T

o find the kink if any, pull the drawer out as much as possible and feel the hose. Might be better if you took the bottom drawer out from the casing and inspect the hose completely. As the problem is limited to upper drawer you do not have to worry about what is under the bottom drawer. Check the water pressure setting is same for both drawers. If so then that is not an issue as bottom drawer is working ok according to your description. See your manual for instruction on how to check the water supply pressure setting on your dishwasher.

Doulbe Draw model receiving an F1 error message.


F1 indicates flood switch has been activated. I wouldn't advise you attempt repair on these drawers- they really require an expert to disassemble (I worked for F+P for 10 years!!). Depending on which model you have (DD603 or DD601v2), repair varies. 603 has a small circuit board that acts as flood switch- located in base beneath drawer- requires drawer to be removed for access. 601v2 model has polystyrene float that acts as flood switch-leaks usually caused by split lid seal(tricky to access- drawer has to be removed) In either case, a leak has occurred and activated flood switch. These drawers are very sensitive to detergents (don't use tablets!!), and the way they are loaded.
Would suggest you get service technician to remedy F1 fault

I havve a Fisher and Paykel Dishdrawer model No. DD601v2. The top draw was stuck in the out position. I fear that the top of the shell casing of the dishwasher is rusted and is blocking the smooth...


When the machine operates a lid comes down on the top of the drawer. This may be jamming.
On the side near the front at the bottom there are 2 plastic slotted screw heads, turn these to horozontal and pull out the "screws" this will release the drawer from the runners and you can lift off the drawer and possibly see whats jamming.

Model 601V2 dishdraw showing U3 error message


I have had my Fisher Paykel dishdrawer for 8 years and it has never completely worked. I would get a U3 code on the top drawer intermittently. I have had my drains rerouted twice, LP - HP reset, service men replace the back flow flap and mother boards without luck... until I was able to get my hands on the service manual. Turns out the solution is quite easy. If you have a problem with the U3 code it means the drawer is not draining appropriately, The washer only gives a preprogrammed 60 sec to drain the drawer. So if your drawer is overfilled, it will think it has a drain problem. The following is taken from the service manual...

"U3 - Time to fill was too short, indicating water was still in the tub.
Possible Causes:
· Drain pump is blocked.
· Drain hose is blocked.
· Sprayarm or rotor not turning
freely.
· Motor electronics have failed.
· Machine set to 'LP' on a high
pressure water supply.

The tub fills with approximately 2.2 litres of water, level with the base of the spray arm attachment. Once this level is reached, the wash pump (which has sensed the fill at 30 second intervals during the fill), becomes primed and pumps the water through the spray arm which will then rotate.
The water level is monitored by sensing the motor load through the electronics."


The solution is to turn your water supply valve part of the way on to limit the gpm flow to the drawer. This way, the drawer will not have over-filled in the 30 sec it took to sense the motor load. I have tried it and wow no more U3. Hope it makes sense and hope it works for you.
