ErC 0004
General Knowledge and Inspection
The ErC 0004 shows up when the IR Ambient is above 80°C. The following list describes the potential cause for this issue:
- Dirty IBTS Lens (incorrect temperature readings).
- Clogged Chaff Filter.
- Inadequate Ventilation Setup.
When the ErC 0004 shows up, follow the instructions below to check your Bullet:
- Check if the IBTS Lens is dirty or misaligned.
- Check if the Chaff Filter needs cleaning.
- Review your ventilation setup.
Checking The IBTS Module
You'll most likely see the ErC 0004 showing up when the Bullet is hot. When this happens, we advise checking the IBTS Lens. This is related to how the temperature sensors work inside the Bullet.
The Inner Workings of Temperature Sensors
In a well-maintained Bullet, the IBTS Module looks for the designated IBTS Preheat Temp (100°C - 310°C). Once reached, the Control PCB Module tells the Induction to stop and start heating periodically to maintain the IBTS Temp. While the Bullet tries to maintain the IBTS Temp, the Bean Temp (reading the air inside the Drum) slowly stabilizes.
As the Bean Temp stabilizes, the B-ROR fluctuation gradually decreases, to a point where it's able to stay at 0 for a while. The Bullet then prompts into Charge Mode, ready for the beans to load into the Drum and start roasting.
When the IBTS Lens gets dirty, the IBTS Module reads lower than it should. This means that the Bullet will now preheat to a higher temperature before maintaining it, consequently heating the air inside the Drum to a higher temperature. Since the air inside the Drum is hotter, the Bullet triggers ErC 0001 when the Bean Temp exceeds 240°C.
Although a warmer ambient temp (above 30°C) can cause the Bean Temp to go higher than usual, the ErC 0001 is usually caused by a dirty IBTS Lens.
Identifying a Dirty IBTS Lens
There are many signs indicating that the IBTS Lens is dirty:
- IBTS First Crack Temps are lower than 195°C.
- The Crossovers between the IBTS Temp and Bean Temp are lower than 190°C.
- The roast degree comes out as darker than usual.
If any of above happens, it's usually a good idea to clean the IBTS Lens first before moving to any other troubleshooting steps.
Cleaning and Aligning The IBTS Module
- Clean the IBTS Lens.
- Disassemble the Control Housing and follow the IBTS Installation Guide to check the IBTS Module alignment.
Checking The Chaff Filter
A clogged Chaff Filter will disrupt the airflow within the Drum, causing the IR Ambient to get higher than usual, and triggering the ErC 0004. If the IBTS Module works fine, we advise checking the Chaff Filter.
If the Chaff Filter appears to be black, brown, or covered in dust, clean the Chaff Filter. Once the Chaff Filter is properly cleaned, you should be able to see through the mesh when you hold it against light.
Reviewing Your Ventilation Setup
If the issue persists after the maintenance, review your Ventilation Setup using Venting The R2. Although the document is made for R2, the general principle for the ventilation setup is the same for R1.
Seek Help From Support
If you have done all of the above and the issue persists, contact your reseller or [email protected] (if you have purchased the Bullet directly from Aillio) for further assistance. The rest of the troubleshooting steps can be considered too complicated for a self-help guide.
