Certain Jenn-Air dishwashers manufactured on the Whirlpool platform may have a power cord junction box connection that can overheat under specific conditions. This advisory applies to panel-ready models where the junction box is located in the lower portion of the door panel.
Affected Models
Jenn-Air panel-ready dishwashers (JDB series) manufactured between 2018 and 2022. Check the model and serial number on the rating plate inside the door frame to determine if your model is included. Contact Jenn-Air customer service with your model number for confirmation.
Symptoms to Watch For
- Burning smell from beneath or behind the dishwasher
- Discoloration or melting near the junction box area
- Dishwasher trips the circuit breaker repeatedly
- Visible heat damage on the power cord insulation
- Scorch marks on the floor beneath the dishwasher
Recommended Action
If you notice any of the symptoms above, stop using the dishwasher immediately and disconnect power at the circuit breaker. Do not attempt to inspect the junction box yourself — this involves high-voltage wiring. Contact Jenn-Air customer service or schedule a professional inspection. A qualified technician can inspect the junction box, verify the wire connections, and apply the manufacturer-recommended repair.
Urgency Level
High — stop using the dishwasher if any symptoms are present. Fire risk if the overheating connection is not addressed promptly.
