My Sage Bambino keeps flashing even after a factory reset. What now?
If you’ve performed a factory reset on your Sage Bambino and the lights are still flashing, it strongly suggests a hardware problem that the reset couldn’t resolve. A factory reset typically addresses software glitches, but it won’t fix physical issues such as a faulty sensor, a damaged heating element, or a problem with the main circuit board. This often indicates a deeper, more complex problem within the machine’s internal components.
At this point, the best course of action is to contact Sage customer support or an authorized repair service. Explain that you’ve already attempted a factory reset without success and describe the specific flashing light pattern. They will be able to provide further troubleshooting steps or arrange for professional repair, which might involve replacing faulty components or diagnosing and fixing the electrical issues.
Could low water pressure cause my Sage Bambino lights to flash?
Yes, low water pressure can indeed cause the lights on your Sage Bambino to flash. The machine relies on adequate water pressure to function correctly, and insufficient pressure can prevent it from completing its brewing or steaming cycles. This often triggers error signals, resulting in flashing lights. Check your water supply to ensure it’s providing sufficient pressure to the machine.
If your water supply is confirmed to have adequate pressure, the issue might be within the machine itself. Scale buildup or blockages within the water lines or the pump can restrict water flow and simulate low pressure. Try descaling the machine and thoroughly cleaning all removable components, including the water tank and filter. If the lights continue flashing despite adequate water pressure and cleaning, it’s likely a problem within the machine’s pump or internal plumbing that requires professional attention.
