F1 flashing on both doors on my Fisher&Paykel dishwasher. Just turned on by themselves.. was not running either top or bottom at the time.

Hi,

from what I'm seeing for the dishwasher, an E1 error means that the door is not properly closed. So, please look at the door of the machine to make sure that nothing is broken or that the dishwasher isn't too full. Thank you.

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.

It is likely the power filter board at the bottom of the bottom drawer is faulty which is causing lack of power to top drawer and F1 alarm on bottom drawer.
Filter board

hello
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

he might have unplugged something in the proccess of drying the bottom

F1 error means the flood switch in the drawer is activated. If there is water inside when you open the drawer then you will have to manually empty it with a small container.

Most likely the solenoid that controls inlet water is faulty or the water level sensor is faulty.

Try turning the mains power and water off and on again and run dishwasher. If fault persists then you may have replace the parts.

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!!

Check at bottom housing both top and bottom drawers for leaks.
Pull the tube out, on the left side below the tub you can access to touch the bottom housing. Dry it out with a tower. Un plug the power cord at least 24 hor so the flood sensor can be dried out before pluggin it back.
However, if you don't fix this leak, the sam F1 problem will happen again.
There is not much clogging up in filter. If you expect something clogged up, you have to take the spraying arm off then take out the bottom stainless steel with a lot of holes out to see the impeller clean or not. Good luck.

Actually the part is called a Link Actuator. There is one for the upper drawer and one for the lower. When the drawer is shut, it will actuate and the dishwasher will lift the drawer up against the upper lid. When the actuator is broken, this will trigger the flood switch which inturn triggers the F1 code. In the meantime, when the dishwasher is turned on, the water will shoot over the side walls of the drawer and get down below to damage the terminal block module.

F1 is a flood code. There are several reasons this could be happening. One, make sure that you are not putting dishes in that are too tall for the drawer and possibly keeping the lid from closing all the way.
Also, on those models, there is a device behind the drawer that guides the hoses and wiring as you open and close the drawer. On older models, this link support was made of nylon and would crack and break loose over time. Then the broken end gets jammed under the back of the lid the next time it is used.
Since the machine is now "wet" it will not stop doing the F! and you should hear the sound of both drain pumps running. The machine is trying to drain itself and it will not allow any other input. It needs to be serviced. Other techs will give bad advice about "just take out the lower drawer and dry up the flood sensor"
Avoid this advice like the plague. There's a reason it got wet and that needs to be determined. There is a diagnostics procedure to make sure the lid motors are operational. This machine should only be serviced by a properly trained Fisher Paykel tech, as many independent techs fancy themselves as Fisher Paykel techs and they know enough to be dangerous...
