Wolf Legacy E Series Code Error 01 x 1: Temperature sensor circuit shorted

What Error 01 x 1 means

Error 01 x 1 on the Wolf Legacy E Series wall ovens, such as the SO30PE/S/PH and DO30TE/S/TH, is the opposite of the open reading: the oven temperature sensor (RTD) circuit looks shorted to the control. A shorted sensor gives a false temperature, so the control stops cooking and holds the code on the display. Your display replaces the x with the cavity number, which shows where to look.

Common causes of Error 01 x 1

Oven temperature sensor (RTD) shorted
Damaged sensor wire touching metal or another wire
Control misreading the sensor input

✓ One safe check you can try

1. Turn everything off and let the oven sit until it is cool. 2. Check that the oven is not showing any heat or burnt smell before you go on. 3. Switch the breaker off for a full minute and flip it on again. 4. Try a short bake. If Error 01 x 1 shows again, leave the oven unused and book us.

! Why to stop there

A short is an electrical condition, and tracing it means opening panels near live power.
A bad sensor, a pinched wire, and a control problem can look the same from the outside.
Our technician measures the circuit and tells you the price in writing first.
Should the same problem return in 30 days from our work, we fix it.

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 01 x 1Error 01 x 1 questions

How does a short differ from code 01 x 0?

Code 01 x 0 means the sensor circuit is open or broken. Code 01 x 1 means it reads shorted. Both leave the control without a trustworthy temperature, so cooking stops.

Could a pinched wire cause it?

Yes, a short can come from the sensor itself or from its wiring touching something it should not. That is why we check the whole circuit rather than only swapping the sensor.

Is it safe to keep trying the oven?

We advise against it. The control cannot read the real cavity temperature, so repeated attempts will not help and may stress other parts. Switch it off and call us.
