Troubleshooting Suggestions
Important Considerations
• Drive cooling is extremely important to the 
overall service life of the product. Extreme care 
should be used to keep cooling air paths clean. 
Drive cabinet enclosures have been designed to 
optimize cooling. Keep cabinet doors closed and 
panels installed to maintain proper operation.
• Resetting a fault will not correct the cause of the 
fault condition. Corrective action must be taken 
prior to resetting a fault. Many drive error codes 
are reset by cycling power to the drive. The fault 
may not reappear until drive operation is 
initiated.
• Drive to motor wiring is critical to proper drive 
operation. Loose or bad connections can generate 
heat and increase current output from drive. 
These problems can manifest themselves in 
operation by many fault codes indicating 
overcurrent condition and maximum retries fault.
Problem/Corrective Action
Problem:
Wash basket does not rotate.
Corrective Action
1. Ensure computer control display on washer is 
showing proper operation.
2. Check power circuit, supply voltage, fuses and 
disconnects.
3. Verify drive to motor wires are damage free, 
properly connected and torqued to specifications.
4. Check belt tension and condition.
5. Verify no mechanical problems exist (i.e., 
binding, motion restriction).
6. Check control input signals. Refer to applicable 
table of inputs.
Problem:
Drive started but wash basket is not rotating.
Corrective Action
1. Verify drive to motor wires are damage-free, 
properly connected and torqued to specifications.
2. Verify no mechanical problems exist (i.e., 
binding, motion restriction).
3. Check control input signals. Refer to applicable 
table of inputs.
Problem:
Wash basket not accelerating properly.
Corrective Action
1. Verify drive to motor wires are damage-free,
