Wolf Legacy E Series Code Error 03 x 0: Probe shorted error

What Error 03 x 0 means

When a Wolf Legacy E Series wall oven, for example the SO30TE/S/TH, shows Error 03 x 0, the official meaning is Probe Shorted Error. The control sees a short on the probe input, so any cooking that depends on the probe may be refused or interrupted while the code appears. In the code the x is a placeholder, and the real display gives the cavity number.

Common causes of Error 03 x 0

Meat probe or its jack shorted
Probe cable damaged or crushed
Probe input circuit on the control

✓ One safe check you can try

1. Unplug the meat probe and take it out of the oven. 2. Let the oven cool, then wipe the probe jack area with a dry cloth. 3. Switch the oven circuit off for a full minute and then back on. 4. Bake without the probe. If Error 03 x 0 stays, stop and call us.

! Why to stop there

If the probe is fine, the short is in the oven's own wiring, which owners should not open up.
Testing the input needs a meter and a known good probe, not guesswork.
We tell you the price in writing before replacing anything.
The repair is guaranteed for 30 days against workmanship issues.

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 03 x 0Error 03 x 0 questions

Should I throw away my probe?

Try the oven without it first. If the code clears, the probe or its cable is the likely cause. If it stays, the problem lies in the oven's probe circuit, and we should look at it.

Can I bake normally without a probe?

Often yes, once the code is cleared by a breaker reset. If Error 03 x 0 keeps returning even with the probe out, the oven needs a visit before regular use.

What does the x mean here?

It stands for the cavity number. On a double oven it tells you which cavity reported the probe short, which saves time at the start of the repair.
