Wolf Steam Oven Code PF: Power Lost While Plugged In

What PF means

Wolf CSO convection steam ovens show PF when the unit lost power while it was plugged in. The oven noticed an interruption in its supply, for example a brief outage or a tripped breaker, and it reports that the cycle was cut short. The owner sees PF on the display and any running program has stopped, so food may be only partly cooked.

Common causes of PF

Brief power outage or flicker at the home
Tripped or switched-off breaker or outlet
Loose plug or supply connection

✓ One safe check you can try

1. Check that other kitchen lights and outlets have power. 2. Look at the breaker panel and reset the oven breaker once if it tripped. 3. Make sure the plug is fully seated in its outlet, if your oven uses one. 4. Clear the display as the manual describes, then restart your program. 5. If PF returns without an outage, call us.

! Why to stop there

A repeating PF can point to a supply problem in the house wiring, which needs a qualified check.
Cooking temperature control could be affected if the supply is unstable, so we do not recommend ignoring repeats.
We find where the interruption comes from, quote in writing first, and give a 30-day workmanship warranty on our work.

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.

PFPF questions

Is PF a damaged oven?

Not by itself. PF is a notice that power dropped while the oven was plugged in. After a known outage, simply clear it and restart. Only a PF that keeps coming back deserves a closer look.

Is the food safe after PF?

The cycle stopped, so the food may not have reached the target temperature. Check it with a food thermometer before eating, and finish cooking or discard it if you are unsure of how long it sat.

What if PF appears with no outage?

Then the supply may be dipping without you noticing, from a loose connection or a weak breaker. We check the supply side and the oven, and give you the price in writing first.
