In this guide, we’ll explain the most common Fisher & Paykel dishwasher error codes—many of which can be resolved at home with just a few basic tools.

What Are Fisher & Paykel Dishwasher Error Codes?

Fisher & Paykel dishwashers use a system of digital displays and flashing indicator lights to communicate internal issues.

How to Troubleshoot Fisher & Paykel Dishwasher Error Codes

Before you begin any repairs, gather the following:

User manual
Phillips and Torx screwdrivers
Multimeter (if you have one)
Flashlight
Towels
Tray or container to catch water

Step 1: Identify the Code

Check your display or light pattern and match it to the list above.

Step 2: Power Down the Unit

Always turn off the dishwasher at the circuit breaker before removing any parts.

Step 3: Apply the Fix

Here are the most common user-fixable problems:

Fixing F1 – Leak Detected
This error often results from spilled water or minor overflows inside the drawer compartment.
What to do:

• Pull out the drawer and dry the area underneath using towels or a sponge.

• If there’s water in the base pan, soak it up carefully and let the area air dry.

• Once completely dry, restore power and check if the error clears.

Fixing F2 – Motor Fault 
While replacing a motor is best left to professionals, sometimes this code is triggered by something simple, like a blocked spray arm.
What to do:

• Remove and inspect the spray arms for food debris or hard water buildup.

• Rinse thoroughly and reattach.

• Try running a cycle again to see if the issue resolves.

Fixing F6 – Water Fill Error
This often occurs when the water supply is off or obstructed.
What to do:

• Make sure the water valve under your sink is fully open.

• Check the inlet hose for any kinks or bends.

• Unscrew and inspect the mesh filter where the hose connects—clean it if clogged with sediment.

Fixing F7 – Drain Fault
This code is commonly caused by a clog or partial blockage.
What to do:

• Remove the bottom drawer and inspect the drain area for trapped food or debris.

• Check the drain filter and rinse it under warm water.

• Make sure the drain hose is not kinked behind the unit or under the sink.

Fixing U1 – Fill Timeout
This is similar to F6 but is time-based. The dishwasher tried to fill and timed out.
What to do:

• Ensure the water supply is on and strong.

• Check for a blocked inlet screen and remove any debris.

Fixing U2 – Loading Error
This is often due to uneven weight or items preventing proper drawer movement.
What to do:

• Reposition heavy items so they’re evenly distributed.

• Make sure nothing is sticking out or interfering with the lid closing.

Fixing U3 – Lid Sensor Fault
Moisture or residue around the lid sensors can cause false readings.
What to do:

• Wipe down the lid area and drawer edges with a dry cloth.

• Let the unit sit with the drawer open for 20–30 minutes before restoring power.
