Pull the bottom drawer out !!!!! To do this on the left and right sides of the bottom drawer you need to pull the pins (Plastic) then pull it out it has hoses still connected pull out and turn on side look in the back left corner (with Pwr off) there is a board there and it has a water (Flood sensor) on it make sure it is dry this is what the Fault code is

What is a U1 code

U1 is a filling fault , so you will have to check the water supply into the dish draw is turned fully open and the hose is not damaged or kinked . Ensure the spray arm inside the draw is free to rotate and clean out the strainers inside as well .It would also pay to check the levels on the machine .If you run the dishwasher whilst using water else where the water pressure may also be dropping to much or even changes in temperature may effect it .

Good luck

How do you fix Error code U1

U1 is displayed on the LCD as a "no tap" symbol. (time out on fill is after 175 seconds)

Possible causes:
• Water turned off
• Insufficient water supply pressure
• Blocked water softener filter (if fitted)
• Spilt rinse aid causing over foam in tub
• Incorrect detergent being used
• Motor rotor
• The machine is siphoning
• Inlet valve has failed
• Controller

P2 is for drain. Make sure there is a bit of water in the base of drawer before you start P2 otherwise the rotor may rub and burn. You can run the diagnostic with drawer open. Be careful not to start P1 as the wash water will splash and flood the dishwashwer.

Do you get any error code on the display?

Does the cycle complete or dishwasher keeps running?
Do you hear the pump trying to drain?

Is it happening in all wash cycles or some?

The easiest thing to do is to check if the filter at the base is clean.
I am assuming the kitchen drain is clear because the other drawer seems to work normally.

Appliance: Fisher&Paykel DD603 Draining

You may want to check up if the water collects in the bottom drawer when the top drawer is in wash cycle (ie, taking water from the inlet) or during the drain cycle when it is draining water out. Leave the bottom drawer open and check while the top drawer is running.

F & P DD603 starts to wash then beeps & flashes U1 - Fill Fault. I have cleaned both drawers & replaced all parts correctly, still comes up with U1.

Have you checked whether you are getting the water supply to the dishwasher. Check if there is no kink in the water hose.

If no problem with water supply then check the water pressure rating is OK for the dishwasher.

E-mail for Fisher Paykel DD603 manual

Josh, you will need to have a Tech out to look at it... F/P will not sell you parts to repair it. The F1 indicates that the flood switch has been tripped. There are many possible causes for this but probably the upper drawer link support has broken and is getting stuck between the lid and the drawer in which case you will need a new lid and link support.

U1 means the unit has failed to prime with water within 3-4 minutes.
Its taking longer than expected to fill with water.
Check the fill valve, water supply problem, excessive sudzing.,reduce your detergent.
