Inspect the Power Cord
Do not use a damaged cord as it poses a shock or fire hazard. -
Measure the Outlet Voltage
Be careful when working with live electricity. If unsure, consult an electrician. -
Test the Charger on a Generator or Known Good Circuit

When to Call a Professional
If the outlet voltage is normal but the error persists, the charger likely has an internal fault. Contact DeWalt customer service or a certified repair center. Also call a professional if you are not comfortable using a multimeter or working with electricity.Frequently Asked Questions
Can I use a voltage regulator to fix error code 6?
Yes, if the issue is consistently low mains voltage (e.g., under 100V), using a voltage regulator or a UPS with voltage stabilization can help. However, if the voltage is normal, the charger is likely defective.
Will error code 6 damage my battery?
The charger will not charge during this error, so it should not damage the battery. However, repeatedly attempting to charge with low voltage may stress the charger's components.
Does error code 6 affect all DeWalt chargers?
This error is common across many DeWalt chargers, including DCB101, DCB102, and DCB107 models. The fix steps are similar for all.
How do I reset my DeWalt charger after error code 6?
Simply unplug the charger from the outlet, wait about 10 seconds, and plug it back in. If the error returns immediately, the low voltage condition is still present.
Can a faulty battery cause error code 6?
No, error code 6 is specifically a mains voltage issue. A faulty battery might cause other error codes, such as error code 1 (defective battery) or error code 2 (temperature issue).
