Wolf Legacy Induction Range Code 30: Data flash error

What 30 means

On pre-2018 Wolf induction ranges such as the IR304TE/S/TH and IR365PE/S/PH, code 30 means a data flash error inside the control. The memory that stores the range's settings and configuration could not be read or written correctly. The display shows 30, and cooking functions may be disabled because the range cannot trust its stored data. Note the exact code, 30, and when it first appeared, since that helps us narrow things down before we arrive.

Common causes of 30

Stored configuration data that failed a read or write check
Control board memory that cannot hold its data
Power interruption that corrupted the data during a write

✓ One safe check you can try

1. Turn all elements off. 2. Cut power at the breaker for about a minute, then switch it back on. 3. Wait for the display to start up and see whether 30 returns. 4. If it does, stop using the range and call us. Do not open any panel.

! Why to stop there

Data and memory issues sit on the control board, which is not something an owner can check safely.
A reset that clears the code once can hide a board that will fail again.
We state the price in writing before starting, with a 30-day workmanship warranty.

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.

3030 questions

What does code 30 mean?

It is a data flash error. The control could not store or read its saved settings correctly. On the older IR induction ranges this points to the control board, not to a pan or the cooktop surface.

Could a power surge cause code 30?

A power interruption during a write can corrupt stored data. A breaker reset may clear it once. If 30 comes back, the control needs testing and probably replacement.

Can I still use the oven side?

We do not recommend using the range while 30 is shown. The control cannot trust its stored data. Call us and we will quote the work in writing before we begin.
