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

F1 (or E1) is a "Flood" fault and means there is water in the bottom pan. This is beneath the bottom drawer. The sensor is in the left, rear corner of the base pan. Any kind of leak, including over sudsing or split hoses or or lid not down fully due to tall items in tub, can cause this. Remove the lower drawer, dry the water from the pan bottom, reinstall the lower drawer and check operation. If this error recurs you must find the leak and correct it.

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.
