TLDR

On your MERRYCHEF eikon e4 unit, error code E 110 indicates a critical SRB and BTS firmware version incompatibility.

Technical Details

Repair Steps:

  1. Verify Firmware Versions: Access the service menu on your eikon e4 (consult your service manual for access steps) and note down the current firmware versions for both the SRB (Safety Relay Board) and the BTS (Board Temperature Sensor). This will confirm the mismatch.
  2. Obtain Correct Firmware: Contact Merrychef Technical Support or your authorized service provider with the recorded firmware versions and your unit’s serial number. Request the compatible SRB firmware version that matches your current BTS firmware.
  3. Prepare for Firmware Update: Ensure you have the necessary update tools (e.g., USB drive with the correct firmware file, if applicable) and follow the manufacturer’s instructions precisely for firmware updates. Power off and disconnect the unit from power before proceeding with any internal access.
  4. Perform SRB Firmware Update: Carefully follow the Merrychef-provided procedure to flash the new firmware onto the SRB. This process is often performed via a service port or a specific sequence within the service menu. Incorrect procedures can cause further damage.
  5. Power Cycle and Test: Once the firmware update is complete, power cycle the eikon e4 unit (turn off, wait 30 seconds, then turn on). Monitor the display for error codes and confirm that E 110 no longer appears. Run a test cycle to ensure full functionality.
  6. Professional Assistance: If you are unsure about performing firmware updates or if the error persists after following these steps, immediately contact a qualified Merrychef service technician. Firmware updates are critical and improper execution can render the unit inoperable.

Common Questions:

Q: What are the SRB and BTS modules in my Merrychef eikon e4?

A: The SRB (Safety Relay Board) is a critical component responsible for safety functions and controls, while the BTS (Board Temperature Sensor) monitors temperatures within the unit. They must have compatible firmware for proper operation.

Q: Can I update the firmware myself?

A: Firmware updates should ideally be performed by trained service technicians, as incorrect procedures or incompatible firmware can lead to system malfunction or damage. Always consult the Merrychef service manual or technical support first.

Q: What happens if I ignore the E 110 error?

A: Error E 110 is critical and will prevent the Merrychef eikon e4 from operating until the firmware incompatibility between the SRB and BTS is resolved. Ignoring it means your oven will remain inoperable.
