Floods top drawer when washing bottom

Flood Pan alert

Troubleshooting an F1 Error in a Fisher & Paykel Dishwasher

https://www.hunker.com > ... > Dishwashers
The F1 fault code indicates that water has filled the flood pan beneath the bottom drawer of the machine. This can happen if the drawer isn't shut all the way, ...

It is the drain water from bottom drawer that is finding its way to the top drawer. This could be due to incorrect drain hose height. Check in installation manual. Alternatively you will have to buy an air gap kit and connect the two drain hoses separately to the kitchen sink.

As the drawers share a common outlet to the kitchen sink drain, it is the drain water from bottom drawer going to top drawer. Can happen if the drain hoses are not following the correct specifications for installation. An air gap kit is available to solve the problems.

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

Fisher and Paykel design a air gap kit to prevent the water back flowing to the other while one is running. it really works and worth of your money. You need to change the lid seal and a pair of actuators from the top drawer. Because of the leak then the floor switch activated not allowing a complete cycle. Need to dry out the wetness from the bottom housing of both top and lower drawers by pulling the tubes out and accessing from the left side with small tower until it completely dry.

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.

The error was a flood fault, water was not draining from either of the drawere, I removed the bottom drawer, dried drip pan and used hairdryer to dry fault sensor, the dishwasher then reset itself and works fine.

I suggest pressing the keylock and power button together, hold for 5 secs, the display will change orange, the display should read HP if it says LP, press the start button to make display read HP.Then press power button to store. You will need to manually removed the water from the machine before restarting
