✓ One safe check you can try

1. Switch the unit off at its breaker for one minute. 2. Restore power and check whether the top drawer responds. 3. Make sure the top drawer is fully closed. 4. If FF returns, leave the top drawer unused and call us.

! Why to stop there

The harness and controllers are behind panels with live wiring.
Three different parts can cause FF, so we test them one at a time.

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.

FFFF questions

Does FF affect the bottom drawer?

FF concerns the top tub. The bottom drawer can often still run, but if it behaves oddly, switch the unit off and let us check both.

What are the four lit LEDs telling me?

Normal, Fast, Delicate and Rinse lit together is the unit's signal for FF. It helps a technician confirm the code even when the display is hard to read.

What will you replace?

We test the harness, the top controller and the mains filter, and replace only the part that fails. You get a written price first, and our 30-day workmanship warranty applies.
