Fisher and Paykel nautilus 920 dishwasher displays a F1 AFTER fix?

Disconnecting the wires to the flood switch will actually cause the fault. Connect the two wires back on to the flood switch using the two outside pins of the 3 in the connector. Make sure float is sitting right down & not operating flood switch. You can raise & lower float manually & should hear switch click on & off. Also check for any corrosion on switch or terminals that would cause a bad connection.
