Fisher & Paykel DishDrawer Code F7: no lid motor current detected

What F7 means

On Fisher & Paykel DishDrawer DD605 series dishwashers, F7 means the controller detected no current at all going to the lid motors. An actuator may be unplugged, connectors on the PCB mains filter or controller may be loose, or the filter or controller may have failed. Owners see F7 and a lid that does not move when the drawer is used.

Common causes of F7

Actuator not connected
Loose connectors at the mains filter or controller
PCB mains filter that has failed
Controller not powering the lid motors

✓ One safe check you can try

1. Switch the unit off at its breaker for one minute. 2. Restore power and try opening and closing the drawer once. 3. Check that the house breaker has not tripped. 4. If F7 stays, leave the power off and call us.

! Why to stop there

Connectors and filter sit behind covers with live wiring.
A missing signal can come from several parts, so we test each.

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.

F7F7 questions

What does no lid motor current mean in simple terms?

The controller sent a command to move the lid, but no electricity flowed to the motors. Something between the controller and the actuators is open or disconnected.

Will a breaker reset help?

A reset can clear a confused controller. If F7 returns right away, the open connection or failed part is real and needs testing by a technician.

Why do you check the mains filter?

The PCB mains filter conditions power before it reaches the controller and motors. If it has failed, current may never reach the lid motors, so we test it before replacing anything.
