Error Code E01: Low Voltage Troubleshooting Guide

Introduction: The Error Code E01 on your heating system signifies a low voltage issue, and addressing this promptly is crucial for the proper functioning of your heater. This error can result from various factors, and this guide aims to provide professional and knowledgeable instructions for troubleshooting.

Battery Voltage Check:
    • The most common cause of the E01 error is insufficient power in the batteries. The heaters demand a substantial amount of power during startup. Ensure that your batteries are adequately charged to effectively heat the glow plugs and initiate the heating process.
Power Cable Considerations:
    • Volt drop can occur if the power cable connecting to your battery is not thick enough to handle the additional 12 amps required during startup. When extending the cable to reach your leisure battery, it is recommended to use a six-millimeter squared cable to minimize volt drop.
Fuse Box Wiring:
    • If you’ve wired your heater to the fuse box, ensure that the cable connected to the fuse box is of sufficient thickness to accommodate the extra 12 amps. It is advisable to connect directly to your battery via the inline fuse attached to the wiring loom for optimal performance.
Controller Configuration:
    • Another potential cause of the E01 error is the controller being set to 24 volts instead of the required 12 volts. Controllers are versatile and can be used with both types of heaters. Verify that your controller is set to the appropriate voltage (12 volts) for your system.
Battery Health Assessment: 
    • Aging or depleted batteries may not provide the necessary power, even if they appear fully charged for standard functions like lights and USB charges. Check for damaged cells inside the battery, especially if it has been repeatedly discharged too low. Consider replacing the battery if needed.
Great Selection of AGM Batteries:
