Fisher & Paykel Built-In Dishwasher Code F30: flooding switch activated

What F30 means

On Fisher & Paykel DW24U6I1 built-in dishwashers from the DW24U and DW60 platform, F30 means the flood switch has activated. Water has collected in the base where it should not be. The advice is to switch the dishwasher off and on, and if F30 persists, to turn the water off, disconnect power and call for service. Owners may also see water around the dishwasher.

Common causes of F30

Water collected in the base from a leak
Door seal or inlet connection that is dripping
Flood switch that remains tripped after water has been removed

✓ One safe check you can try

1. Turn off the water supply valve under the sink. 2. Switch the dishwasher off, then disconnect power at the breaker. 3. Mop up any water on the floor and look at the door seal for debris. 4. Do not run the dishwasher again. Call us and describe where the water was.

! Why to stop there

Water in the base can reach live parts, so power must stay off.
Finding the leak means opening the lower area.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F30F30 questions

What should I do first when F30 appears?

Turn off the water supply valve, then cut power at the breaker. Those two actions stop more water entering and remove the electrical risk. Then call us before running the dishwasher again.

Can I just reset it and keep going?

You may try one off-and-on reset, but if F30 persists the published advice is to shut off water and power. A flood switch that trips again means water is still collecting.

Will you check for floor damage?

We inspect the dishwasher and its connections, find where the water came from and quote the repair in writing. If water reached the cabinet or floor, tell us so we can note it.
