Wolf CSO Steam Oven Code E48 / F8: relay K6 or its supply circuit

What E48 / F8 means

On Wolf CSO convection steam ovens such as the CSO24 and CSO30 series, E48 with F8 means actuator relay K6 is stuck. The official causes also list a damaged element or relay board, and a relay supply circuit that is defective or a plug that is not fitted correctly. The oven stops and shows the pair.

Common causes of E48 / F8

Actuator relay K6 stuck
Element or relay board damaged
Relay supply circuit defective
Plug not fitted correctly

✓ One safe check you can try

1. Kill power at the panel. 2. Wait a full minute, then turn it back on. 3. Watch whether E48 / F8 clears. 4. If it returns, leave the oven off and call us. Do not unplug or reseat any internal connectors yourself.

! Why to stop there

A loose internal plug and a failed supply circuit look similar from outside.
Only testing shows which of the four causes applies.
We quote in writing before work and warrant the repair for 30 days.

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.

E48 / F8E48 / F8 questions

What is different about E48?

It adds the relay supply circuit and a plug that is not fitted correctly to the usual relay causes.

Could this be a loose connector?

The listing says a plug not fitted correctly is a possible cause. That is an inside-the-oven check for a technician.

Can the oven be used meanwhile?

We would not. Keep it off until the relay circuit is inspected.
