To resolve home charging issues with a 2017 Tesla Model 3, follow these detailed steps:

Inspect the Charging Equipment

• Examine the charging cable and connectors for any visible damage or wear. Damaged equipment may need replacement.
• Check whether the connector is properly clicked into the car's charging port. A loose connector will not charge effectively.
• Ensure that the charging adapter being used is compatible with the Model 3 and is in good condition.

Check the Power Source

• Verify that the electrical outlet is functioning by testing it with another device. If the outlet is not working, check your circuit breaker or contact an electrician.
• Ensure that the outlet provides the correct voltage and amperage for home charging. A 240V outlet is recommended for faster charging.

Reset Charging Settings in the Car

• Access the charging settings on the car’s touchscreen to ensure they are correctly configured.
• Try resetting them to default and then input your desired settings again.
• Check if the charging limit is set too low; adjust it as needed.

Software Updates

• Ensure that the Model 3's software is up to date. Tesla regularly provides updates that can fix charging problems.
• Connect your car to a Wi-Fi network in order to download and install any pending updates.

Inspect the Charging Station or Wall Connector

• If you use a Tesla Wall Connector, check for any indicator lights that might signal an error. Refer to the Wall Connector manual to understand the meaning of these lights.
• Reboot the charging station by turning the power off and then on. This may resolve connectivity issues.

Check Environmental Factors

• Weather conditions can affect charging efficiency and performance. Ensure that the car and charging setup are not exposed to extreme weather.
• If the temperature is very low, precondition the car to ensure the battery is at an optimal temperature for charging.

Contact Tesla Support

• If all else fails, contact Tesla customer support for professional assistance. They may need to check the vehicle's logs remotely or schedule a service appointment.
