Question about Fisher and Paykel 24 in. DD-602 Built-in Dishwasher
Runs for a while and then starts beeping with a red light and U3
The U3 error code could mean a few things. Not sure if you get it in both or just one drawer.
It could mean there is something blocking the drain pump. Lift the filter plate and drain filter. Then remove the rotor by disengaging the collar holding the impeller and rotor assembly. clean the area including the channel between the rotor cavity and the drain sump. Put everything back and test.
If this does not get rid of the U3 then it is possible there is a kink in the drain hose. Pull the drawers out and check behind. If nothing visible then other possibility is the inlet water pressure setting is not correct. If you know how to read the water pressure setting from the display then compare the setting on the two drawers.
Please post a comment to let me know what you find.

SOURCE: Error U3
That's a "Low Pressure" fault and it's possible you may only need to reset the mode. This question is posted under DD603 but a U3 code is usually associated with the 602 models. I am including an instruction for you on how to check the setting. Start with that first, it is easy to do.
Let me know if you are not able to read the text.

SOURCE: beeping and red light stating U3
Hi and welcome.
You posted your question in the DD/DS603 series section, but code U3 is usually seen on a DD/DS601 or DD602 series. When this code appears, most comon cause is that the machine is set in LP or LOW PRESSURE mode and needs to be set to HP or HIGH PRESSURE.
The fault is sensing water level too high in the drawer, which can also be caused by a blocked drain or inoperative pump. I can tell you exactly how to tell if the machine in in the wrong mode if you can tell us the correct model number. The machine's pump/drain system can easily be checked by putting the machine in diagnostic mode and running the drain pump.

This will get the drive back, but you WILL lose the data. If you need the data. I do not know the answer. Repost your question to go to Sandisk site below
'.............U3 smart drives come preinstalled with the U3 Launchpad
which emulates the Windows OS start menu, and controls program installation and
hence facilitate the portability of software. However, if you would like to use
the USB flash drive or memory key as a pure normal USB mass storage device, or
you don't use operating system that U3 supports (i.e Windows XP and Windows
2000 operating systems), or you simply feel that U3 Launchpad and applications
have bugs such as unable to eject due to locked files in use, consent on
privacy and automatic installation of U3 software and pop-up etc, you can uninstall
and remove the U3 Launchpad from the USB storage device.
To remove and delete the U3 Launchpad, you need to download
U3 Launchpad uninstallers or U3 Launchpad Removal Tool that remove the U3
Launchpad and re-configure the USB drive to be a single mass storage USB drive.
Currently, U3 Launchpad uninstallers are only available for and must be run on
Windows XP or Windows 2000 machine. When uninstalling, the U3 smart drives USB
device has to be plugged in with U3 Launchpad running.
U3 Launchpad Removal Tool for SanDisk USB U3 devices can be
downloaded here, http://u3.sandisk.com/
WARNING: U3 Launchpad removal is irreversible. You won't be
able to install U3 again. Beside, backup your data before begin uninstallation
process as ALL data will be erased.
UPDATE: It's impossible to reinstall U3 LaunchPad........."
