Disconnect the power supply for few minutes, say 15 minutes and then turn it on.If the same error displayed, read below :-

Your appliance has experienced the ubiquitous F1 flood error. The only way to stop the beeping is to remove power. Your course of action depends on the next step. You need to look BEHIND the lower unit drawer. Remove power, then open the lower drawer all the way, and press those plastic tabs (down at the sides, along the bottom and just below the round buttons)- inwards. Now slide the drawer out a couple inches more. You can now see behind the drawer.

Is there water in the catch pan? If no, the Mains Filter Board beneath that plastic cover in the back is bad. It thinks it's flooded while in fact it is not. Replace it.

If there IS water back there, you need to find where it's coming from. Usually, the fill and drain hoses are NOT at fault. Go into Diagnostics Mode, and operate the water fill valve (FV), and look for leaks at the valve and along the fill hose as the tub fills.

(You'll want to remove that large plastic cover in the back to see the valves and hoses coming from them. Lift the drawer off its rails and set it off to the left if there's space for it. Upper drawer, set it on top of the bottom drawer).

Operate the drain pump (P2) and look for leaks in the drain line. If no water is seen leaking from those sources, go on to the Lid Motors and the Link Supports.

First inspect the link support (that white plastic rod that spans the tub service lines). They typically snap in two at the mid span point. If it's snapped, there's your problem. Replace it with the updated link support. Also run the Lid Motors (LD). As they transition up and down, do they respond strongly, or do they sound weak and labored? If the motors are in a white plastic case, you have the old motors and they will need replacing soon anyway. When they grow weak their ability to pull the seal down strongly is diminished.

Should you get an F1 error code on the TOP UNIT ONLY, it means that the LOWER UNIT has experienced some failure in the Water Heating Circuit. You will need to test those components to detect what has failed. Get out the schematic and your multimeter!!

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    If it is one drawer, then there could be many reasons that could cause this. This is a common and most subjective of all the errors.It could mean that the ' Flood Switch is activated or faulty '.Other than this few common causes i have seen would be :-

    1. Lid not sealing correctly.

    2. Water
      level in tub too high.

    3. Leaking water inlet valve.

    4. Dishdrawer
      not priming correctly.

    5. Split spray arm.

    6. Spary arm not
      turning freely.

    7. Water leak from the drain hose.

    8. Water
      leaking around the heater plate o-rings.

    9. Drain hose partially
      blocked or restricted.

    10. Condensation around the chassis flood
      switch PCB.
    The best thing to do is turn the power off ,remove
    the bottom drawer by pushing in the clips on side of the drawer ,just
    below the round plugs. The clips are attached to runners, push them
    back to release the drawer and ( after taking out the rack and spray
    arm) put the drawer on its r.h.side. Mop up the all water in the base,
    then remove the cover that goes over the back L.h. corner, this will
    expose the mains/flood switch board ( make sure you dry the roof of the
    drawer before you take the cover off , or water can drip onto the board
    .....not a good thing!!!

    To remove the cover, push in the clip in the
    middle front edge of the cover with a flat blade screwdriverand slide
    the cover foward a bit, then put the screwdriver under the clip and
    twist up, the cover should now pull off to the right. Spend a couple of
    minutes drying the board with a hair dryer and mop up any remaining
    water ( be careful of the board again). Refit the cover and switch back
    on ( you shouldn't need to force the cover on, just slide it on from
    right to left , but you may have to push down the cover just above the
    clip to get it to lock once it is located correctly). If it doesn't F1
    again ,all good, if it does , remove cover and redry, and repeat until
    it doesn't.

    To refit drawer, slide out L.h. rail and sit
    drawer on it, then lift right side of drawer and slide out other rail
    and sit other side down. If the rails don't want to slide foward and
    lock, lift the drawer at the front while sliding the rail fowarduntil
    the front edge of the rail is just at the clipping gap at the side of
    the drawer, then make sure the drawer is sitting down firmly on the
    rails and pull clips foward to lock. If the drawer has been clipped in
    correctly it will slide in and out nicely, if not , look at the back
    edge of the drawer when it is fully open to see where it is sitting too
    high and rectify by refitting the rail on the affected side/sides. By
    this point if any part of the bottom drawer was broken ,you would have
    seen it. Also check the top drawer by releasing it and pulling it
    foward,shine torch in and have a good look.

    Hopefully it
    won't leak again unless ther is a faulty part not visible to the naked
    eye, check by running one drawer for a couple of minutes, stop the cycle
    and open the drawer and check the outsides for water ( don't be too
    worried if you see water in the bottom between the drawers as it will
    drip from the roof, unless the drain or fill hoses are split ) ,if ok,
    run the other drawer and check.

    Remember, if you get to a
    point where you don't feel confident with what you doing or you think
    you might break something, leave it and call a professional to do the
    job, you may save money in the long run and if you going to expose
    wires or connections always switch off and unplug before removing the
    cover, you don't know whats underneath
    Let me know,if needed further assistance.

    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

F1 Error code

F1 is flood error. basically water has arrived at the bottom board. you can unplug the dishdrawer, remove the bottom drawer and dry the board at the bottom, maybe with a hair dryer carefully. this will reset the fault, but this is a fault that may appear again. replace the actuators that close the lid of the drawer that is leaking (look for signs of water running our of one of the drawers).

Red F1 error warning appearing on LED readout after dishwasher stars.

Assuming you are getting the F1 error in both drawers.

This means there is water at the base of the housing under the bottom drawer.

Turn power off and take the drawer out. You will have to pull out the plastic pins on either side and get the front cover off. This will enable you to pull the drawer out from the slide bar for better access. Use towels and hair dryer to get rid of all the water. The flood switch is mounted on the power board. Use hair dryer to dry this out.

Put everthing back and turn power on.

Post a comment if this is not fixed or the F1 is only coming in one of the drawers.

Machine powers on by itself both drawers.. with the error message

F1 can mean two things - depending on which drawer it is coming in.

It is a sign that the water is leaking from the drawers into the base of the housing and tripping the flood switch.

To fix this you will have to take the drawers out and dry out the flood switch at the base of the housing. Use towels and hair dryer. Most like the dishwasher detergent is foaming or the door seal is leaking or the outlet drain is cracked. Make sure the mains power is turned off when you are working on the dishwasher.

The other reason is if the thermal cutout is blown in the lower drawer that can cause the F1 to appear in top drawer. But if both drawers are flashing F1 then this is unlikely.

DD603 Does Seal need replacement? F1 Error Code

F1 error code appears because moisture has been detected by the flood switch on the base of the housing under the drawer.

If you think the door seal was not fitting properly then that too can cause moisture leak into base of the unit where the flood switch is located. Steam condensation would also lead to moisture.

Best option might be to replace the door seal for the top drawer. This is not a trivial thing as the unit has motor actuated door seal which can be tricky to fit back in.

Also avoid foaming in the detergent by using the correct powder and not tablets.

Fisher & Paykel single drawer dishwasher F1 flashing.

F1 indicates a problem with the Flood sensor. I cleaned all the filters etc. removed the drawer viewed under the drawer, it was dry. There is nothing further I can do, so called the Appliances repair person and booked an appointment for him to determine if an outlet hose is blocked or has a hole in it or whatever. Thanks for all the suggestions Blokes. I'm technically challenged. Happy New Year

Troubleshooting problem with two drawer fisher & payke dishwasher

F1 is a flood code and is an indicator that water has escaped from one or both drawers. It is usually caused by placing too tall of a dish in the drawer or from failed parts such as the older style "link supports" or a faulty lid motor. It also can be a chronic problem if the machine is not installed correctly.

Fisher paykel dish drawer

The motor impeller is located inside the tub.
To remove/inspect:
1. Remove dishrack and filter
2. Twist the strainer lock ring counterclockwise to disengage.
3. Lift and remove strainer and lock ring assembly
4. Remove impeller, inspect for damage and/or debris in sump.
Hope this helps....

The F1 code is retained in memory as the most recent fault (may have happened awhile ago) and may not be related to the current issue.
However FYI

F1 code can be caused by several things:
1. Defective lid motor(s)...Each drawer has two lid motors that pull the lid tight to the drawer when the cycle is started. (this was very common on early models)
2. Something too tall was placed in the drawer preventing the lid from closing completely.
3. (only seen this once) the drain hose developed a crack causing water to leak only when draining.

Dish drawer leaks

The f1 is a flood error. There is a sensor in the bottom reading water. You have to dry it out before you can do anything or the drain pump will just keep running. Check the lid of the drawer you where using to see if anything may have been holding it up or if the seal is torn. If that looks ok you will have to check the lid actuators to see if one is not working. I would replace both right and left if one is out.
