Wolf M Series Code 1E22: Both Lower Bake Element DLBs Open

What 1E22 means

Across the Wolf M Series wall oven range, from the SO30TM and DO30PM to the SO3050 models, code 1E22 reports that both DLBs for the lower bake element are open. The control sees open line-break paths on both sides of that bake circuit. You will see 1E22, and the lower oven is likely to bake weakly or not at all.

Common causes of 1E22

Both lower bake element DLB paths open
Shared connection to the lower bake element circuit loose
Control board relays that did not close

✓ One safe check you can try

1. Turn off the oven; do not open the door to speed things along. 2. Shut off the oven breaker for about a minute before turning it back on. 3. Try a short cycle to see if 1E22 comes back. 4. Persisting 1E22 is our cue; please keep the oven off until we arrive.

! Why to stop there

Two open paths in one circuit point to a shared cause, and finding it needs testing. The lower bake circuit carries high current.
Testing first keeps the bill limited to the part that actually failed.
No work starts until you approve a written price.

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.

1E221E22 questions

Why do I see 1E22?

Both DLBs for the lower bake element read as open, so the control cannot complete the circuit it needs to heat that element. 1E22 guides our first tests, and the work follows only after your approval.

Why would both DLBs open together with 1E22?

That suggests something they share, such as a connection or the control output. We test to find which instead of replacing parts at random. A visit lets us confirm 1E22 in person, so you only pay for what is needed.

What still works with 1E22?

Other oven functions may carry on, but the lower bake will be weak or absent. If you have a double oven, the other cavity may keep working. Call us for a written quote.
