Fisher & Paykel DishDrawer Series 9 Code A09: sanitize temperature not reached

What A09 means

On Fisher & Paykel DishDrawer Series 9 models such as the DD24DI9 and DD24SI9, A09 means the sanitize cycle did not reach the temperature needed to sanitize the dishes. The drawer finished or stopped without confirming that level of heat. Owners see A09 after a sanitize cycle, and the dishes are clean but cannot be treated as sanitized. It usually follows a sanitize selection.

Common causes of A09

Incoming water not hot enough for the sanitize stage
Heating that did not reach the target temperature
Sanitize cycle interrupted before the final heat stage

✓ One safe check you can try

1. Run the kitchen hot tap until it is hot. 2. Restart the sanitize cycle without opening the drawer during it. 3. Do not stack items so tightly that water cannot circulate. 4. If A09 returns on every sanitize cycle, call us. Use a lighter load next time.

! Why to stop there

Heating and temperature sensing are inside the base.
Cycle results matter if you rely on sanitizing.

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.

A09A09 questions

Are my dishes dirty after A09?

Not necessarily. A09 says the sanitize temperature was not met, so the dishes may be clean, but they cannot be called sanitized. Rewash them with a fresh sanitize cycle if that matters to you.

Does hot tap water help?

Yes, giving the drawer hotter water at the start helps it reach the target. Run the hot tap before starting, but stay under the maximum supply temperature for the drawer.

When should I call?

If A09 repeats on every sanitize cycle with good hot water and an unrestricted load, the heating needs testing. We quote in writing first and back repairs with 30 days.
