Maytag Dryer Error Code D16

D16 indicates a Gen 2 Card Reader Communication Fault. The dryer's control system did not receive a health check signal from the connected Gen 2 debit card reader within 30 seconds. As a result, the dryer displays OUT OF ORDER and stops accepting use until communication is restored. This fault is specific to commercial Maytag dryers equipped with a card payment system.

Start by checking that all wiring harness connections between the Gen 2 card reader and the control board are secure and free of corrosion. Verify that the card reader is receiving consistent power. If connections are tight and power is good, try cycling power to the card reader to clear a potential firmware lockup. If the fault persists after these steps, the card reader module or the communication wiring may need to be replaced.

Repair costs depend on what is causing the communication fault. If the issue is simply a loose wiring connection, there may be little to no parts cost, with only a service call fee if a technician is involved, typically in the range of $75 to $150. If the Gen 2 card reader module needs to be replaced, total costs including parts and labor can range from $150 to $400 or more depending on the specific reader model and local labor rates.

Yes, D16 is a self-clearing fault. Once the communication link between the control board and the Gen 2 card reader is reestablished, the error clears automatically without any manual reset needed. If the fault keeps returning, there is an underlying issue with the card reader, its wiring, or its power supply that needs to be diagnosed and corrected.

When D16 is active, the dryer displays OUT OF ORDER and is not available for use, so the machine itself prevents operation. The fault relates to the payment card reader system and not to any heating, mechanical, or fire-safety component of the dryer. Once the fault clears and the dryer returns to normal operation, it is safe to use.
