Frequently Asked Questions
Common questions about Maytag FAE1 error
The FAE1 error on the Maytag MDB7959SKZ indicates a problem with the vent or airflow system used during the drying cycle. The sensor detects whether the vent fan is operating correctly. When dishes are still wet at cycle end or FAE1 appears, the vent fan motor or its detection sensor has likely failed and requires a technician's diagnosis.
Yes, the dishwasher will typically still wash and rinse dishes normally when FAE1 appears. The error affects the drying phase, meaning dishes will likely be wetter than expected at the end of the cycle. You can open the door at cycle end to air-dry dishes as a temporary workaround while scheduling a service visit.
