How to Troubleshoot Mitsubishi PW23 Pallet Jack Issues: A Step-by-Step Guide
Asked Apr 10, 20160 views1 answer
I am experiencing issues with my Mitsubishi PW23 pallet jack, which suddenly stopped working. We received a quote for new batteries at $3,200, but considering we bought the jack only two years ago and have already spent a lot on repairs for the same issue, I'm hesitant to invest more. The jack has approximately 500 hours of use. When I turn the key, I hear a clicking sound, and the red "STOP" icon lights up. I tested the jack using the battery pack from our other PW23 pallet jack, but the same issue occurred. I don't trust our local Mitsubishi repair service, so I need help getting my PW23 back up and running.
Troubleshooting Mitsubishi PW23 Pallet Jack Issues
If your Mitsubishi PW23 pallet jack has suddenly stopped working, it can be a frustrating experience, especially if you’ve already invested significantly in repairs. The following guide will help you troubleshoot the issue and provide context for potential solutions.
Common Symptoms and Initial Checks
When your pallet jack shows symptoms such as:
- A clicking sound when turning the key.
- The red "STOP" icon lighting up.
- An error code displayed on the console (in your case, E 1504).
These signs indicate that there may be an electrical or mechanical issue at play.
Step-by-Step Troubleshooting Guide
1. Check the Battery
- Inspect the Connections: Ensure the battery terminals are clean and securely connected.
- Test with Another Battery: You mentioned testing with the battery from your other PW23. If the same issue persists, it’s likely not a battery problem.
2. Review Error Code E 1504
- Understanding the Code: Error code 1504 indicates protection against high battery temperature or overheating. This could be caused by:
- A malfunctioning converter.

It sounds like you're dealing with a tricky situation with your Mitsubishi PW 23 pallet jack. Since you've already checked the hydraulic oil pump motor and the drive motor without finding any shorts, the next step is to address the error code you're seeing, which is `E 1504`. This code indicates a protection mechanism against high battery temperature or overheating, suggesting there might be an issue with the converter or control board that regulates the voltage.
To troubleshoot further, you might want to swap out components that control the current from your working pallet jack, provided it's not in use. This can help you identify if the problem lies within those parts. However, I understand your concern about risking the working jack, so proceed with caution.
Unfortunately, there isn't a reset procedure for this error code. It typically points to a hardware issue that will likely need the attention of a certified technician. If you can, keep an eye on the components and see if any visible damage or wear is present. If the error persists, it would be wise to consult with a professional who can perform a thorough check-up and determine what parts might need replacement.
If you have any follow-up questions or if the issue resurfaces, feel free to reach out for more assistance.
