Fisher and Paykel Nautilus showing error F1 and is beeping

Sorry did not see your problem report earlier. If you have checked the sensor under the bottom drawer and it is dry, then F1 is caused by top drawer power filter fault. This means the bottom drawer controller is giving the F1 error but the top drawer controller has no power. Can you confirm this.

F1 display means Flood has occurred. Call the company for more assistance. Here is a link- http://www.fisherpaykel.com.au/admin/pdfs/pdf_usecares/521766I_DW920_ugm_NZw.pdf

The F1 error coming on top drawer when operating bottom drawer is due to the thermal fuse blowing up on the bottom drawer and shutting controller power.

The thermal fuse could have blown either as a normal component failure or heater over heated due to thermostat failure. In any case this can be repaired by replacing the whole heater assembly as all the parts are integrated.

This is at the underside of the drawer and will need a technician to replace unless you are very familiar with repairing electronic dishwashers. The part look like this.

The way you have described the onset of the F1 error is not due to flood switch. You can confirm that the lights on the bottom drawer are out even though the top drawer is showing F1 and beeping.

If problem was flood switch then both drawers would show F1.

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.

f1 means u have a leak where pump and control module is. that is located under sump.the water has activated a flood switch near drain pump. need to find leak to fix problem. make sure power is off to unit b4 looking.please reply to how u go. good luck

F1 error indicates flood switch in base has activated, meaning machine has leaked. This causes machine to drain continously, and can only be stopped by switching off power. Not easy to fix if you don't have experience- bottom drawer has to be removed to access flood switch, then machine needs to be test run and checked for leaks. Best to call the professionals!!

It leaked before leading to this.
1- Unplug the power.
2- Dry out the leak.
3- Before taking off the lid seal, check if Lid actuator working by going to diagnostic mode. 4- Select LD.
5-Pull the drawer half way out so you can see the lid going down or not when you turn on by pressing lock button.
6- Press the lock button again to release the Lid.
7- Most the time it is a Lid actuator problem and your seal look good, then you replace the Lid actuator only.
8- If it is a problem with the Lid actuator and your seal look bad then replace all .

The f1 code is caused moisture in the electronics part most likely in the door.see if there is any way that you can see where moisture might get in and plug that spot up. In the case of the f1 code when not using the dishwasher leave the door propped open to help dry out the electronics.
