Fisher and Paykel Seal / Gasket replacement

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.

There is water collected at the base of the dishwasher which is tripping flood switch. Will need to disconnect power and take the bottom drawer out and dry out the base. Need to find source of the leak. Most likely the lid seal or hoses.

The lid seal in DD602 works like a balloon. If the seal is cut then the air escapes and will cause the lid not to seal leading to leakage and flood switch trip which shuts dishwasher down.

See the following video.
You can buy the seal from this site but use the correct product code of your dishwasher to make sure you get the right part. The product code is engraved on the label located on the front under the top drawer.

please provide the model number of the dishwasher so that I can identify the type of lid seal it is using. Usually the lid seal actuator motors are stuck and prevent drawer from opening. You could force it open with a slight tug. Otherwise turn the mains power off and on and see if it makes any difference. Need to check the lid seals for damage otherwise it may leak in future and cause flood switch to trip.

The lid seal on the top drawer is faulty and needs replacement. It might be cut or damaged and is obstructing the drawer from closing. THis also may have caused the flood switch to trip as water can leak if drawer is not sealed.

This could mean a lot of things depending on what the last state of the dishwasher is. For a double dishdrawer unit it could mean the power to the top unit has blown. But more commonly there is a water leak causing the flood switch at the base of the dishwasher housing to trip. The leak could be due to damaged lid seal, cracked hose or using very strong detergent which causes foaming. Assuming the power to both the drawers is ok. Let us work on the flooding problem. Remove power to the dishwasher (take power chord out). Extend the lower drawer out and use towels to mop up the base (under the drawer, hard to get to). Then take a hair dryer and run it inside. Give it an hour or so to fully dry and connect power and try again. Good luck.

This could mean the lid seal of the drawer is not sitting properly.
I would not be running the dishwasher in this condition as the water will enter the base of the dishwasher and trip the flood switch. This will then prevent you from running both the drawers until the base of the dishwasher is dried. Not a very easy job to get there.

F1 can mean two things - depending on which drawer it is coming in.

It is a sign that the water is leaking from the drawers into the base of the housing and tripping the flood switch.

To fix this you will have to take the drawers out and dry out the flood switch at the base of the housing. Use towels and hair dryer. Most like the dishwasher detergent is foaming or the door seal is leaking or the outlet drain is cracked. Make sure the mains power is turned off when you are working on the dishwasher.

The other reason is if the thermal cutout is blown in the lower drawer that can cause the F1 to appear in top drawer. But if both drawers are flashing F1 then this is unlikely.

Top right corner: it means the bad right actuator could not pull down the lid seal on that side causing a leak. The actuators are sold in pair. They are not expensive. Replace both of them when you order them in. Need to inspect the rubber seal around the top lid since if it is distorted another 60 bucks to get a new lid for replacement also. The new lid comes with the york to engage with the actuators.

About 3 years either the lid seal is going bad or the actuators had a problem. These things prevent the seal from properly seal on the top of your tube then causing a leak to the bottom hosing of each drawer. If you pull out the tube you can see the bottom housing is wet. Based on what you described, I can see the bottom is on the top drawer. When it leaks so much, part of the leak is coming down to the lower one. The flood at the lower bottom housing is less then from the the upper one.
