Fisher and paykel twin draw

there is water in the base setting off the flood sensor, you will need to remove the bottom draw and dry the water up with a towel (make sure the power is off and unplug it from the power point) then you will need to do a bit of testing to locate the cause of the leak, if your lucky the leak was caused by incorrect dish stacking or something too big in the draw

you will need to replace both draws control boards, with the dd603 control boards they have a small touch button panel on the top of the board which they didn't put a protective layer or plastic over and basically what happens is steam gets on the copper tracking and corrodes it hence the fact it doesn't work anymore, all new control boards even the replacement for yours comes with a plastic strip over the board. hope this helped

Excess water in

the DishDrawer

Drain hose(s) bent or

kinked.

Straighten the drain hose(s).

Blocked filters and/or drain

hose(s).

Clean the filter plate/drain filter. Unblock
the drain hose(s). Refer to the user manual

If the problem is with both drawers, then most likely kitchen side drain is blocked. But if only one drawer, then need to clean filter and drain sump at base or if pump motor is not running then replace the pump rotor.

If both drawers are having the problem then it is unlikely the drain pump is the problem. You may need to check the blockage in your kitchen drain or if using garbage disposal unit then ensure it is clean and not blocking the drain.

Flood switch is at the very bottom underneath the bottom draw in the base floor.Unplug cord.Open bottom draw all the way & squeeze a towel or sponge under the draw & soak up the water..The washer should work now..Why did it flood in first place?
Check that dishes are not stacked higher than top edge of the draw otherwise it can't seal.this can happen when children are asked to stack the dishwasher.Another cause is some models the seal is an inflatable tube that seals the top edge of the draws,it gets cut or sliced buy a plate that was stacked to high when you closed the draw.there should be no clunk of dished hitting when the draw is closed.

The controllers get very brittle & can break away from their housing, the reason it's rapidly beaping is because it thinks the door is open. PLEASE TURN IT OFF FIRST AT THE POWER POINT. Take the front draw panel off by pulling the plugs situated on the front behind the draws, the controller is at the top right hand side if it is loose then thats the problem, double sided tape will work but lots of it or try a wedge type arrangement. I know this is an old post but people refer to these for solutions much later.

Check to see float switch (located on the bottom of cabinet below bottom draw )hasnt moved or dislodged in transit.(Access by way of back panel-easiest) or removing bottom draw.

The f1 is a flood error. There is a sensor in the bottom reading water. You have to dry it out before you can do anything or the drain pump will just keep running. Check the lid of the drawer you where using to see if anything may have been holding it up or if the seal is torn. If that looks ok you will have to check the lid actuators to see if one is not working. I would replace both right and left if one is out.

check the lid switch if it beeps fast.
