One of the most common causes of a coffee machine's screen not working is a power supply problem. Check the power cord to make sure it is securely plugged in and all connections are secure. If this does not solve the problem, check if there is an external power source, such as a surge protector or a spare battery, that may be interfering with the power supply.
Another possible cause could be a faulty control board or related components. If the machine is still under warranty, contact the manufacturer to have it checked and repaired. If not, you may need to purchase a new control board or contact a repair technician who can locate and replace the damaged parts.
If all else fails, the last resort may be to rebuild the coffee machine. This can usually be done by unplugging it from the mains and plugging it back into the mains. In some cases, it may be necessary to press the reset button or follow the other instructions that come with the specific model of coffee machine.
The following steps should help to resolve the problem of the coffee machine screen not working. If the problem persists, please consider contacting a professional repair technician for assistance.
