SOURCE: I have a Fisher Paykel

just had the same F1 error message. I figured the drain lines were clogged so i hooked my compressor up to them and blew air in the lines for about 5 seconds at 60 psi. It is not giving me the error message anymore and seems to be running fine.

F1 means that water is in your basepan--- you can pull the bottom drawer out and soak up the water with a towel... you will have to use a hair dryer to dry underneath the control sensor in the back left corner.

SOURCE: f1 showing up - no flooding.

Check for water under the bottom drawer or water marks. Try swapping the motor controllers over from top to bottom. Theses are the computer modules in the front of each drawer. Cheers

F1 flood switch is on

The F1 code in both drawers could mean flood at base of dishwasher (under bottom drawer) . If it is occuring only in bottom drawer then it is likely the power circuit for top drawer is blown.

Need to know which of the above to give advise on how to fix.

Fisher & paykel fault "F1" is displayed on the top

F1 means the flood sensor senses water at base of machine at PC board.
You need to take out bottom drawer and check for water puddle under where the drawer was.If there is water you can get the machine going again by comletely drying it out(F1WILL CLEAR),but it still means you have a leak.With bottom drawer out you can really see whats going on.Once F1 is clear you can actually run upper drawer and see if it leaks.Most likely culprit are the lid actuators.Replace all 4 . It'll run like new.Don't overload drawer .That can cause lid leak too.Also the PC board may be damaged and may start to go crazy giving fake F1 codes.$80 easy fix.
good luck

You will need to be a bit more specific when you say "no flood".

Are you having this F1 fault in one or both drawers?

What did the engineer do when he was there last time?

Does the F1 code flash with beeps?

What happens when you turn the mains power off and on after a short delay?

F1 fault

F1 code would mean the flood switch is activated.

In Nautilus people have found this to be caused by a faulty door seal.
Water seeps under the diswasher base panel and finally the flood switch (a protection) activates.

The solution is to replace door seal after drying out under the base panel.

Hi, I have missed place my manuel for my dishwasher. It is a single-draw stainless steel, model DS603. The problem I have is F1 is showing on the control panel and it has a beeping sound. How do I rectify...

The manual for your unit is available on

However, this will give you only the reason for the F1 fault code but not the causes for it.

This occurs when the flood switch at the base of the dishwasher (under the drawer) is activated. This is because there is some water gone into the base of the unit.

Causes can be - leak in the drain hose (that is at the back of the drawer) or too much foam in detergent or simply water spilling from over the drawer.

If there is a leak in drain hose then this needs to be replaced.

Parts manual is available for your unit at

You might be able to source it locally.

To get rid of the F1 - switch off the dishwasher power.
Extend the drawer out as much as possible and dry out the base with towels and hair dryer. The location of the flood switch is shown in the parts manual in case you are interested. Turn the power on and hopefully it was a once of problem.

Good luck

F1 display flashing?

Flashing wrench means a fault code has been triggered.
F1 is the fault code when flood switch at base of dishwasher cabinet turns on.

This can occur due to several reasons when moisture gets to the base of the drawer cabinet.

You will have to turn the power off and extend the drawer out as much as possible to expose the back of the cabinet. Take towels and a hair dryer to dry the base. Once the flood switch gets dry the problem will go away.

The main thing is why did the water get there. You could have a crack in the hose or simply the detergent may have caused too much foam.
