Well it is a drain blockage code. Check the pipe. I had a blockage caused by the stalk off an apple and an accumulation of lint!

U1 is a water supply error , it explains it all in this manual Cheers

OE error code is an Outlet Error.

That has to do with the drain itself. It can come up when the unit is draining slowly, it has nothing to do with water-level really. I would suggest makign sure that your drain hose is not crimped / crushed / or obstructed first before going onto other problems.

Hi
Error code U1 means that the dishwasher might be taking longer time then required to fill the water and water is not draining properly as something might be blocking the drain pump assembly due to which the water is leaking. To solve this issue you'll have to take the front lower access panel out and then clean the drain pump assembly completely, also clean the impeller and chopper assembly located at the bottom of the unit. Also check the water supply and spray arm. After this is done the issue should be resolved, if not then check the float switch mechanism and make sure that it is fine. Error F1 on your fisher & paykel means an overfill condition. One of the most common causes for an overfill fault is that the dishwasher cannot pump out the dirty water due to a plugged drain hose. Check the drain hose if it is clogged. Now remove the bottom drawer from the unit to inspect the flood switch. Remove the wire harness cover on the underside of the drawer. With the bottom cover off, unclip the wire harness, fill hose, and drain hose. Then unclip the linkage at the back of the drawer and lift the drawer off the slider arms. Now' you'll be able to look at the flood switch. Note the positions of the wires on the flood switch and remove them. Then unclip the switch housing from the base panel. The switch housing contains one switch for each drawer. The switches are wired normally closed (NC) and each switch has three spade connections, so it's important to note where the wires went. Now clean the contacts and let it dry. Hope this helps... Please post back if you need more information.

The U1 code means:-
Dishwasher attempted to fill to correct level but failed. = Water tap not turned on. Turn the water tap on.
Too much foam. Rinse aid setting too high or has been spilled. = Turn the rinse aid dial to a
lower setting or wipe the spill. Incorrect detergent. Ensure that you use a detergent that is intended for a domestic automatic dishwasher. Egg yolk. Place an extra tablespoon of detergent in the dishwasher door for pre-rinsing.
Too much detergent. Use the recommended quantity of detergent
Wash pump faulty. Call your Fisher & Paykel Dealer or Authorised Service Centre.
Dishwasher not draining. = Drain hose bent or kinked. Straighten drain hose so water can flow through. Strainer blocked. Empty out the strainer and ensure the filter plate is clear of food
particles..

Hi,

"U1 error code" means the unit has failed to prime with water within 3 minutes. Its taking longer than expected to fill with water. Check the fill valve,it might be due to water supply problem, or the spray arm might not be in the exact position place.Check the above to fix this error code.

Thank you !!

I had the same issue (Electrolux ESF 6251). I had both error codes 10 and 30. I found that the short hose connecting the inlet valve (solenoid) to the tank was cracked. That explained error code 30, but even after replacing the hose I still got error code 10. I checked water supply and also drain hose and filters. I realized that I had recently tried to flush out lime scale and suspect that the drain or pump had lines could have clogged up. I tried pumping into the floor drain inside the dishwasher (removed the filter cartridge and screen) simply with a suction cup like you use in the kitchen sink. Voila. Now it works again...

Hi. The above machine stops mid cycle and drain/fill light is on, also error code F3E, have cleaned both hot and cold water inlet filters, also checked drain pump and drain line, all ok. Machine drains with no issues and fills with hot water, runs for a while then shuts down.
Any ideas?

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.
