Re: Touch buttons dont always work on a dd603 dishwasher
Hi and welcome to FixYa! If you are talking about the cycle selector buttons up on the top edge of the drawer, I can help you with this. When the selector button gets wet or has moisture buildup or soap residue, it will not sense the touch from your fingertip. It is not a mechanical button per se. If you take a clean dry cloth and wipe the recessed area where your fingertip touches the button, it will respond 100% better than it will when it is dirty or just plain wet. I show my customers this practically every day. The only other thing that will cause this is the tab behind the control panel sometimes cracks and will not hold the computer tightly against the underside of the drawer edge. This is rare though. Clean the surface of the drawer edge and it will change cycles again like new.

you will need to replace both draws control boards, with the dd603 control boards they have a small touch button panel on the top of the board which they didn't put a protective layer or plastic over and basically what happens is steam gets on the copper tracking and corrodes it hence the fact it doesn't work anymore, all new control boards even the replacement for yours comes with a plastic strip over the board. hope this helped
The likely reason for top drawer not starting wash program when you press start button is the drawer home sensor is either faulty or the drawer is misaligned. This means controller thinks the drawer is open and does not start the cycle.
Assuming the bottom dishdrawer is working ok, it is likely the controller on the top drawer is either faulty or sensing some incorrect signal. If pressing any of the panel buttons makes no difference, then most likely the controller is faulty.
By the way I am unclear why you mention two models in your problem description. DD603 is a double drawer dishwasher and DS603 is a single drawer unit.
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
The DD603 dishwasher from Fisher and Paykel is a very sofisticated electronically controlled dishwasher. It does not have a control panel or electrical panel unlike some of the other brands of dishwasher which are electromechanical controlled.
So if it is stopping with 10 minutes left on the LCD display, then it might have simply gone into the Dry mode. A small fan in the door unit starts up and sends warm air into the unit. At this time the dishwasher gives a couple of beeps. You will have to wait until the time display goes to 00 provided the dishwahser is set to be in the Clean Dish indicator option is on. This means the washing is complete. Refer your instruction manual.
It is also a good practice to keep the area around thw wash program button (on the drawer door top edge) clean. Sometime grime can cause false trips.
First off, clean the surface where you select the cycles, over on the right side of the drawer edge. Clean up the entire surface, so that when you lightly touch the cycles, It changes instantly. Also, you said "dd603" but the LP/HP modes are for model 601 and 602. Open the drawer, select normal first. Now with two hands, hold your fingers over the two outer-most buttons, one on the left side and one on the right. Wait up to six seconds and then the LEDs should all come on in an orange color and the display should show the LP. Press the lock button once, it should change to LP. Make sure you are looking for a manual for a dd601/602. You can get them free at http://www.fisherpaykelparts.net
