Fisher & Paykel Built-In Dishwasher Code F90: data or electronics error

What F90 means

On Fisher & Paykel DW24U6I1 built-in dishwashers and the DW60FC6 models in the same platform, F90 is a data or electronics error. The control has hit a problem with the information it stores or exchanges internally, and it stops the cycle. Owners see F90 on the display and the dishwasher may not respond to normal keys. The advice is to switch off and on once.

Common causes of F90

Temporary data error in the control
Electronics that no longer store or exchange data reliably
Power disturbance that corrupted the control's information

✓ One safe check you can try

1. Switch the dishwasher off with its power key, and if it will not respond, turn off its breaker for one minute. 2. Restore power and switch the dishwasher on. 3. Start a short cycle. 4. If F90 appears again, leave the dishwasher off and call us.

! Why to stop there

Electronics errors cannot be cured by cleaning or hose checks.
Opening the dishwasher exposes mains wiring behind the panel.

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.

F90F90 questions

What does F90 tell me?

It tells you the control hit a data or electronics problem. It is not about water, filters or hoses, so the usual cleaning steps do not apply to this code.

Can a power outage cause F90?

A power disturbance can upset the control's stored data, and a restart then clears the code. If F90 returns after a clean restart, the electronics themselves need testing.

What does a repair involve?

We confirm the code, test the control and its power supply, and tell you whether a replacement is needed. You approve a written price first, and the work carries our 30-day warranty.
