Wolf Legacy E Series Code Error 07 x 0: Inner bake relay shorted

What Error 07 x 0 means

Wolf Legacy E Series wall ovens such as the SO30TE/S/TH show Error 07 x 0 when the inner bake relay is shorted. In practice the control sees the inner bake circuit powered when it should be off, which can mean the element stays on. The oven stops cooking and holds the code on the display. The digit shown where the code has an x is the cavity number.

Common causes of Error 07 x 0

Inner bake relay stuck closed (shorted)
Relay output damaged on the relay board
Control failing to switch the relay off

✓ One safe check you can try

1. Turn the oven off at the control and open the door to let heat escape. 2. Shut the breaker for a minute, then bring the oven back on. 3. Restore power and see whether the oven heats with nothing set. 4. If Error 07 x 0 shows up again, call us rather than restarting the oven.

! Why to stop there

A relay that is stuck on can keep an element powered, so this needs careful handling.
Replacing the right board part requires testing live circuits, which owners must not do.
We give you the price in writing before work begins.
Our 30-day workmanship warranty stands behind the 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.

Error 07 x 0Error 07 x 0 questions

What does a shorted relay mean here?

The relay contacts that feed the inner bake element behave as if they are welded closed. The control notices the element has power when it was told to switch it off.

Why is it rated serious?

A stuck-on heating circuit can overheat the cavity. We treat it as a priority: cut the breaker if the oven stays hot and call us.

Is the opposite problem a different code?

Yes. Error 07 x 13 reports the inner bake relay open, meaning it will not close. This code is the shorted case, so the repair path is different.
