I received the F1 code on the top drawer, and no power to the bottom drawer. Tried drying the flood board, no luck. Found a burned spot on the controller for the lower drawer. Replaced the controller, the mains filter board, and the hose link support. Still no power to the bottom drawer and still receive F1 code on top drawer. What next?

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).
Not sure what the actual model number is but usually the F1 error with Fisher and Paykel dishwasher means water has entered the flood switch located at the base. This could be due to leaky hoses or water leaking through the door or lid seal. Wait for a day or two until the water evaporates and try again. Otherwise you will have to dry out the flood switch and then try again. Location of flood switch will depend on your model. For double drawer dishwasher you will have to take the bottom drawer out from the housing and the switch is on the floor of housing. But make sure you take the mains power chord out before touching the insides of dishwasher. Will also need to find the cause of the leak. Other reason for F1 could be loss of power to top dishdrawer if you have double drawer. But in that case the top drawer will have no lights on. The power board is located on the base of housing under bottom drawer. Once again do not touch inside of dishwasher without shutting off mains power.
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
The flood switch is at the base of the dishwasher housing under the bottom drawer.
Do you have the F1 fault displayed in both drawers? If so, or if you have single drawer, then turn power off and take the bottom drawer out. Dry the base with towels and use hair dryer on the small circuit board at the base.
Put everything back and turn power back on. The source of leak could be lid seal, kink in hose or ruptured hose.
If you have 2 drawer unit and the F1 error is in top drawer only then the bottom drawer has lost power. Could be due to thermal fuse blown on heater plate.
ok, the machine flooded and the water has leaked into the bottom of the machine, 1st turn off the machine at the power point. 2nd- open the top drawer and remove the suds from it. 3rd. open the bottom drawer and look under it to the bottom of the cabinet . that is where the water will be. use a torch if you have to. now you need to dry the water up. you can do this with a hair dryer or a fan heater. the reason the machine is flashing F1 is because the water has triggered the flood switch and you need to dry up that water. please reply 4 more help.once dryed F1 will disappear. please make sure all the suds are removed from the top drawer. good luck
Below is the service manual link and a web site that I found. refer to the lower section where a person writes in that the fixed the flooding with a hairdryer. I hope this helps, they seem like fantastic dishwashers.
Just had the same problem, removed the excess water from the drawers, turned off the power, removed the bottom drawer by pushing in the lugs at the bottom of the drawer where it butts up to the drawer front and pulling out the drawer. Then had to mop up with 4 t-towels and half a roll of kitchen roll the water in the bottom of the machine housing. The water gets into the electronics at the rear of the housing and obviously warns you of this by the F1 code?. I removed the white cover over the electronics with a screwdriver by pushing it into a slot then sliding the cover across to the right, it is indicated on the cover how to remove it. I also then removed the screw on top of the PCB (printed circuit board) and lifted up the grey plastic base and wiped under that and the under side of the PCB. The PCB unclips on the left hand end of it and lifts out, try not to pull the cables out though. I then used a hair dryer as suggested by someone else on here to dry out any excess that you could not wipe dry, my daughters Hello Kitty hair dryer didn't last long though, she's not impressed! So try not to stick the dryer right in the housing to avoid overheating it. About 5 minutes did the trick for me, then re-assembled everything, turned it on and hey presto! It worked!!!! Its not that hard, good luck!!!
