E:01 ⎯ Communication Error

The E:01 error code signifies a communication issue within the Speed Queen commercial dryer’s electronic control system. This typically occurs when there is a malfunction or misalignment in the infrared communication between components. To address this, ensure the micro-wand is properly aligned and free from obstructions. Users should also check for any blockages in the infrared sensor. If the problem persists, resetting the dryer by unplugging it for 30 seconds may resolve the issue. Consulting the manual or contacting a professional is advised for further assistance, as persistent errors may indicate a need for component replacement or advanced troubleshooting.

E:05 ─ Invalid Value Communication

The E:05 error code indicates an invalid value communication issue in the Speed Queen commercial dryer. This occurs when the electronic control receives incorrect or corrupted data from the micro-wand during operation. To resolve this, ensure the micro-wand is properly aligned and free from obstructions. Verify that no foreign objects are blocking the infrared communication path. If the issue persists, resetting the dryer by unplugging it for 30 seconds may help. Refer to the manual for detailed instructions. Persistent errors may require professional assistance to inspect or replace faulty components, ensuring reliable operation and preventing further disruptions.

ESh ⎯ Dead Short in Temperature Sensing Circuit

The ESh error code indicates a dead short in the temperature sensing circuit of your Speed Queen commercial dryer. This occurs when there is an unintended electrical path in the temperature sensor or its wiring, causing the sensor to malfunction. To resolve this, inspect the temperature sensor and its connections for damage, corrosion, or improper installation. If damage is found, replace the faulty component. Ensure the sensor is properly calibrated and securely connected to the control board. If issues persist, consult a professional technician or refer to the manual for detailed diagnostic procedures. Addressing this error promptly is crucial to prevent further damage and ensure safe operation.

Specific Error Codes and Their Solutions

Addressing specific error codes ensures efficient troubleshooting for Speed Queen commercial dryers. Each code, such as Alrm, Er, Ub, Er, Co, and Er, Dr, provides insights into underlying issues, allowing targeted solutions to restore functionality and prevent future malfunctions.

Alrm ⎯ Break-In Alarm

The “Alrm” error code, known as the Break-In Alarm, is triggered when the service door or coin vault switches on your Speed Queen commercial dryer are not properly closed. This safety feature prevents operation when these access points are open. To resolve this, inspect and ensure all switches are securely closed. If issues persist, check for faulty switches that may require replacement. Regular maintenance and consulting the user manual can help prevent future occurrences of this alarm.

Er, Ub ⎯ Fatal Unbalance Error

The “Er, Ub” error code indicates a fatal unbalance error in your Speed Queen commercial dryer. This occurs when the dryer detects an excessive imbalance during operation, often due to an uneven load or issues with the drum or rollers. To resolve this, ensure the dryer is installed on a level surface and check for obstructions in the drum. Resetting the dryer by unplugging it for 30 minutes may also clear the error. If the issue persists, inspect the rollers or drum for damage and consider consulting a professional technician. Regular maintenance can help prevent such errors and ensure smooth operation.

Er, Co ─ Communication Error

The “Er, Co” error code signifies a communication error in your Speed Queen commercial dryer, often due to issues with the card reader or micro-wand alignment. This error disrupts the interaction between the dryer’s control board and other components. To resolve this, ensure the micro-wand is properly aimed and aligned with the reader. Check for loose connections or damaged wiring between components. If the issue persists, resetting the dryer by unplugging it for 30 minutes may help. If the error reoccurs, consult a professional technician to inspect the communication circuit. Regular maintenance and ensuring all connections are secure can prevent this error from recurring.

Er, Dr ─ Drain Error

The “Er, Dr” error code indicates a drain-related issue in your Speed Queen commercial dryer, typically caused by a clogged drain system or improper venting. This error occurs when the dryer detects excessive moisture due to slow drainage or blockages. To resolve this, inspect the drain hose for kinks, blockages, or damage. Ensure the venting system is clear of lint and debris, as poor ventilation can prevent proper moisture removal. Clean the moisture-sensing components and verify that the drain pump is functioning correctly. If the issue persists, check for any obstructions in the drain system or consider professional servicing to ensure optimal performance and prevent further errors.

Troubleshooting and Maintenance Tips

Regularly clean lint filters, inspect venting systems, and check drain hoses to prevent errors. Schedule routine maintenance to ensure optimal performance and extend the dryer’s lifespan.
