Error code U3 could mean the drain pump is blocked.

Remove the trays and the impeller arm. Empty the water with small container or towel. Open the filter plate and drain filter. Get the motor out and check the cavity for any rubbish. Also use a stiff thin wire to clean the passage between drain filter and motor cavity. The instructions for removing the filter plate and motor assembly are in the user guide.
Good luck

I believe this error code is due to flood switch at the base of the dishwasher housing getting activated. You will have to look behind the bottom drawer after pulling it out as far out as possible. if water is visible then after turning off the power, try to dry the base of the housing with towels and hair dryer. Make sure the power supply is turned off.

There are many causes of the water collecting -ranging from cracked hoses, broken actuater arm or too much foam due to incorrect dishwasher detergent (tablets can cause this). Need to fix the cause.

It is not clear if the problem started suddenly or whether you have been doing some reconnection / renovation work and have reconnected the dishwashers.

F1 means the flood switch is activated, ie, the dishwasher is not able to control the inlet water.

This happening at the same time in both drawers is hard to understand. Have you tried shutting off and turning on the water supply? Is there any chance the water pressure has changed from the normal for your supply.- How to check what pressure your unit is set for is shown in the user guide - HP or LP. But I am not sure you can check that if the F1 display comes on.

You will need a technician to look at it if problem does not go away.

I suppose you have a double drawer dishwasher and this problem is with one of the drawers.

One cause of the impeller not rotating would be that there is some loose cutlerry lodged between the impeller arm and the base rack. This is easy just remove it.

HOwever, the other option is that the impeller itself is stuck. Try opening the filter base plate and removing the impeller rotor to check if no debris is lying around (usually food scraps).

The instructions to open the filter plate and exposing the impeller is in the user guide. If cleaning does not help then check nothing is stuck in the filter sump and the narrow passage connecting filter sump and the rotor cavity which is preventing the rotor from rotating.

The worst case scenario is the impeller rotor is faulty. You can buy this and replace yourself , ie, if you worked out how to remove it.
Good luck

I am assuming you have an integrated double drawer unit DD603I.

The instructions for removal and refit of the drawers is available in the Installation Manual. I am able to locate one on the following site


You may also need instructions to prepare and fit the front panel of the cabinetry to the drawers which you can down load from

Hope this is what you are after.

About 3 years either the lid seal is going bad or the actuators had a problem. These things prevent the seal from properly seal on the top of your tube then causing a leak to the bottom hosing of each drawer. If you pull out the tube you can see the bottom housing is wet. Based on what you described, I can see the bottom is on the top drawer. When it leaks so much, part of the leak is coming down to the lower one. The flood at the lower bottom housing is less then from the the upper one.

Have you checked the child protect is not on. Refer your user manual to disable it.

I think HP display is linked to the inlet water pressure. You have inadvertently pressed the wash program buttons on the top of the door and pushed two button together. What you might be seeing is the setting for selection of water pressure. Perhaps best option is to put off power at the mains, wait a few minutes and put power on.

Try to keep the edge of the door and the wash program selector buttons free of grime

You can download the parts manual for the DD603H from fisher and paykel and check which latch you need. The diagrams are given in it.


Fisher and... | Answered on Nov 08, 2009

I am assuming it is the motor rotor assembly.

To take the old one out you remove the filter plate. Instructions are in the user guide. Dowload from fisher and paykel site if you don't have it. Once the filter plate is out, hold the faulty rotor assembly with the impeller blades and pull out. Can be a bit hard to pull out. Try rotating in its cavity a bit. Place the new one exactly in the same position with a few light twists of the impeller

Replace the filter plate - make sure the notches match the grove on the base and twist. (the instructions are in the user guide.

Hope this helps.

If the overflood message is coming with both drawers then it appears something is not good around the plumbing where unit is connected to water supply. Some leak in inlet side or drain side.

On the other hand if only in one drawer then most likely the float switch is faulty or the solenoid on water inlet is failing. good luck. In general these units are sensitive to dirt if not kept clean. Try also to wipe the grime off door surrounds from inside.

Fisher and... | Answered on Nov 05, 2009

Not sure if this problem you are having is with both the drawers or just one of them.

F1 fault is linked to water level float switch being activated. But not sure why the unit turns on by itself. Take a clean cloth and wipe dirt around the door inside especially around the switches. The unit is very sensitive to contamination around the door edges. Good luck. Otherwise a technician on-site is your best bet.

There is a water leak in the bottom housing and a leak sensor detects to give a F1. Pull out the tube and put your hand in the front from the left ( only on this side has enough room to access) with the small towel to dry out the water on the bottom housing. After dry out, unplug the power for at least 24 hours so the sensor can be dried out and reset. However, make sure to fix the leak from the top seal, otherwise, it keep happening.

Try putting clean dishes in the unit then have it run. If they would come out dirty then you would need to clean out the unit especially the food debris. Have the filter checked out and have it cleaned. With or with out the test with the clean dishes it is always advised to have the unit cleaned in order for you to inspect some loose joints or worn out parts while cleaning.

We have one too and it cleans the dishes really nicely. However, you have to be sure you look after the filter screen. Hard water could also be a problem if the detergent you use does not have an additive in it and you should always use a rinse agent (pour it into the reservoir in the front).

In order most likely and easiest first: 1) Be sure nothing you put in the racks goes below the level of the rack. If it does it will block the spray arm from turning and you will get semi-cleaned dishes and soap streaks as you describe. My sister had the same problem and swore nothing interfered with the arm, but the way she loaded some things permitted them to move during the first few revolutions of the rm and stopped it. Check to see if the arm rotates freely for about two rotations after a load is finished and the conditions you describe appear. 2) Check the filter screen located in the bottom of each drawer under the silverware holder. You have to lift the hinged portion of the rack to get to it. Clean it well and reinstall it. It should be checked every three loads, or once a week at least. 3) Then check the holes in the spray arm to be sure they are open. If plugged clean them out carefully. 4) Then if that does not work, dissamble the arm, and motor (covered in the instructions or available on line, and be sure nothing is plugged in those areas. 5) Cll a repair man who really knows the unit - not all do and they can do more harm than good.

The unit will clean very well. Good luck!
