Wolf CSO Steam Oven Code E35 / F13: cabinet opening is too hot

What E35 / F13 means

On Wolf CSO convection steam ovens such as the CSO24 and CSO30 series, E35 with F13 means an over temperature condition. The official causes are a cabinet opening temperature that is too high, which may come from a second appliance, a cool air fan failure, and a power failure during operation. The oven shuts down to protect itself and shows the pair.

Common causes of E35 / F13

Cabinet opening temperature too high, possibly from a second appliance
Cool air fan failure
Power failure during operation
Over temperature inside the oven

✓ One safe check you can try

1. Turn the oven off and let it cool completely. 2. Check that the cabinet opening has the clearance around the oven and is not blocked. 3. Move anything heat-producing away from the cabinet. 4. Run a short test after cooling. 5. When E35 / F13 shows up again, book a visit.

! Why to stop there

A failed cool air fan needs testing inside the oven.
Heat from a neighboring appliance is a site issue we can help you identify.
We give a written price first and a 30-day warranty on repairs.

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.

Can the oven next to it cause E35?

Yes. The listing names a second appliance as a possible source of the high cabinet temperature.

Is a power outage a cause?
