Wolf Oven Error Code 1522

Error code 1522 means the oven control has detected that both dual load break (DLB) relay contacts in the broil element circuit on the lower oven relay board are open. This disables the broil function as a safety measure. The code points to a fault within the relay board's switching components. Replacing the lower oven relay board is the first recommended diagnostic step.

When code 1522 is active, the broil element circuit is disabled, so the broil function will not operate. Bake and other oven functions may still work depending on your model, but you should not attempt to bypass the fault or force the broil element to operate. Continuing to use the oven in a degraded state while a relay board fault is present is not recommended until the board has been inspected and replaced.

The total repair cost will depend on the price of the replacement lower oven relay board and labor charges in your area. Relay boards for Wolf ovens typically range from around $150 to $400 or more depending on the specific model. Adding professional labor, you can expect a total repair cost somewhere in the range of $250 to $600. Getting a quote from a Wolf-authorized service provider before proceeding is a good idea.

Replacing the relay board involves working near high-voltage components, so it should only be attempted by a qualified appliance technician or an experienced DIYer who is comfortable working with 240V circuits with the power fully disconnected. The repair itself involves accessing the lower oven relay board and swapping the faulty board for a new one. If you are not confident working with high-voltage appliances, hiring a certified Wolf service technician is the safest option.

Resetting the oven by cycling the power or tripping the circuit breaker may temporarily clear the display, but the code will return if the underlying relay board fault is still present. Because this code points to a hardware failure in the relay board, a power reset alone will not resolve the problem. The relay board needs to be inspected and replaced to permanently clear the fault.
