Have Fisher and paykel Nautilus dishwasher showing F1 fault - what does this mean? Dishwasher was leaking water all over the floor dont think major problem as it starting draining when power was reset

The F1 error on a Fisher and Paykel dishwasher means the flood switch was activated for seven seconds or longer. ... The dishwasher's flood switch could activate because the water is leaking around the heater plate. It would still eventually show up somewhere, though a leak like that would kill the heater plate too.

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

Hi - unfortunately my good friend it cannot be reset as one would like quite easily anyhow... water has found its way to the base of the drwaers and have activated the flooding switch - one could pull it apart to dry it - tip the water out from the base but if the leaks not repaired you will have the same problem later and will be on-going.

ok , F1 means your flood switch has activated, which is underneath the drawer. now they show the F1 fault because of 2 reasons.1st there is still water underneath drawer causing switch to activate. 2nd your activator board which has the flood switch attached is faulty reading your posting it has been about 15 days since the fault happened. the water should have dryed around switch by now. if there is power to the unit and it is still coming up with F1 fault then possibly you have damaged the activator board. please reply and tell me if you have power on or off at the present time. to fix the problem it is alittle bit involved but i can guide you thru it when you reply .good luck

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 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!!

My dishwasher's doing exactly the same thing. What was the solution?

Code F1 indicates that Flood switch has been
activated which explain why you feel that it is overfilling.

Water leaking
Drain hose disconnected
from waste pipe.
Reconnect the drain hose to the waste pipe.
Supply inlet hose not
properly connected.
Ensure the inlet hose is connected securely.
Other leaks. Turn water and power supplies to the
Dishwaher off.
