Tip & How-To about Fisher and Paykel Dishwashers

F1 faults

F1 is a water leak error, it means water has filled the base of the unit and shorted across the filter board flood sensor (this how it is intended to function), now can be a number of different things, we will start with easy stuff, 1. to much detergent can bubble over the overflow hole in the draw and run into the base take note if there is excessive suds in the draw you should have only a thin layer on the surface of the water. 2. the lid that comes down when you close the draw to seal off the draw is being held up by something that is too high (you shouldn't put anything in that is taller than the handle of the cutlery basket) either that or the seal itself or the motors that pull the lid down are faulty, 3. you may have a leak through the heater plate seal (easy to check open the draw and look underneath it, on the bottom of the draw there will be a plastic cover protecting the coils and heater plate simply look at it to see if any water is pooled in it or if there is any dried soap or water. 4. if not any of these you will be looking for a leaking pipe or water hose. 5. and on the rare occasion your filter board itself may be corroded from water contact making it think it is permanently being touched by water

Our fisher and paykel dishdrawer won't wash. It comes up with F1 and flashing light on control panel.


the dynamo dishwashing stuff has caused foaming which reached the base of the dishdrawer unit causing the flood switch to trip. This gives F1 error.
Not sure how much foaming has occured.

Best to turn off power and take power cable out from socket. then empty the drawer using towels. pull out the bottom drawer and wait a day or so to let the foam disappear from the bottom of dishwasher (under the bottom drawer). Connect the power and see if F1 had gone. If not, you need more work. Post a comment based on the above suggestion and I will guide you further if required. Always use Finish dishwasher power only (recommended quantity) as the drawers are small and don't need much detergent.

how do i reset. F1 fault code is on. i fixed the flooding


then u havnt fixed it, if you fixed the flooding it should automatically stop showing the error if you have dryed the water from the base of the unit under the draw when u take it out and it still saying F1 then your mains filter board has been cooked as they use a small circuit board as the flood sensor with a little tab that sticks out to sense any water touching it if the leak was pretty major the machine may hav not been able to stop it before the board went under water, they have actually made upgraded filter boards with a gel coating over it to prevent such things from happeing

FI error message from both drawers. We had a


F1 indicates flood fault. There is no reset, machine thinks it has flooded. If machine was running OK until electrical storm, then it could have shorted the mains filter control board (DD603 models-this mains filter board also acts as flood switch), although this is unlikely to have shorted. More common is dishwasher has had a leak causing F1 fault, or corrosion on mains filter board . Open bottom drawer and shine torch underneath to see if there is any water in the base of the cabinet- if yes, machine has leaked and activated flood switch. If not, flood switch board may be faulty.
Unfortunately, access to this flood switch control is permitted only by removal of the bottom drawer- recommend calling technician unless very keen!! If keen, read on!!
-To remove drawer- there is a tag at the bottom front on each side of drawer when you open it -just below the round plastic plug. You need to push this tag in and slide backwards on each side, then drawer will lift out-Careful as hoses and wiring still attached, but long enough to allow access. Mains filter control board is located under plastic cover at left rear- press tag on plastic cover and slide to the right- you will now see small electronic board. This is the mains filter board that doubles as the flood switch. It is held in place by 1 screw- you need to remove wires from board before removing it). Check circuit board for corrosion or evidence of short circuit- if so, replace circuit board.
Good luck, but advise seeking professional help unless you very confident!!
