What 0821
actually means.
Wolf ovens lock the door for self-clean with a motorized door latch, which Wolf abbreviates MDL. Code 0821 says the relay that drives the upper oven's latch reads as shorted, so the control can no longer be sure the latch will move when told to. The lower oven's version is 0822.

What to do when 0821 shows on the ovenKind of codeDoor and lock
The motorized lock did not reach the position the control asked for, or its switch reported the wrong one. Most often this shows during or after self-clean; the latch, its switches and the door's alignment are checked before the lock motor is replaced.

Before you book,
in this order.
Each step comes from Wolf's own guidance for 0821 on its ovens. Follow it to the end: the last card says whether this is a visit.
Turn the breaker off for about 30 seconds, switch it back on and check whether the door opens and closes normally.
Do not start a self-clean cycle while 0821 is showing.
If the code returns, book a visit.

What not to do
0821 is not a door hinge or gasket problem. The door may close perfectly well; the issue is the electrical side of the lock.
