ErC 2048

General Knowledge

The ErC 2048 shows up when the Bean Probe is not connected or if the Bean Probe reading is below -40°C.

This can happen due to several reasons:

• The Bean Probe is disconnected.
• The Bean Probe is connected to a wrong connector.
• The Bean Probe Wire is crimped between the Metal Insert and Front Plate.
• The Bean Probe Wire is broken.
• The Bean Temp is below -40°C.

Identifying The Issue

When the ErC 2048 shows up, recall if you have recently maintained the Bullet.

If you have, check the Bean Probe connection. If you haven't, check if the Bean Probe Wire is broken, or if your ambient temperature is below -40°C.

Troubleshooting

Checking the Bean Probe

1. Follow the Bean Probe Replacement Guide to access the Bean Probe Wire.

2. Check if the Bean Probe Connector is correctly connected.

   

3. Check if the Bean Probe Wire is crimped between the Front Plate and Control Housing.

4. Continue the disassembly to check if the Bean Probe Wire is crimped between the Front Plate and Metal Insert.

   

   Tip

   Check if the Bean Probe sits entirely inside the grooves.

5. Check if the Bean Probe Wire is damaged on both ends.

If the issue persists after the Bean Probe is properly installed, the Bean Probe requires a replacement. Contact your reseller or [email protected] (if you have purchased the Bullet directly from Aillio) to order the part.

Pros only - Continuity and Resistance Test

Warning

Only do this if you have an understanding of electronics and know how to work with a DMM (digital multimeter). If you don't, please reach out to [email protected].

Using a DMM, you can follow this image to test for the Bean Probe's resistance:

The Bean Probe's resistance is 80~90kΩ under room temperature (25°C). The lower the ambient temp, the higher the resistance. If your Bullet is showing ErC 2048, you might see the DMM displaying 'OL'.
