Common Causes of Flashing Espresso Machine Lights
The flashing of espresso machine lights is often an indication of a specific issue or malfunction. Here are some of the most prevalent causes:
1. Water Tank Empty or Misaligned
An empty water tank is a common culprit behind flashing lights. Ensure that the water tank is filled to the appropriate level and securely placed in its designated slot.
2. Coffee Grinds Overflowing
Excessive coffee grounds in the portafilter can obstruct the water flow and cause the lights to flash. Use the appropriate amount of grounds and tamp them evenly to prevent overflow.
3. Clogged Filter Basket
A clogged filter basket can restrict water flow and trigger flashing lights. Clean the filter basket regularly to remove any accumulated coffee grounds or debris.
4. Faulty Brewing Unit
A malfunctioning brewing unit can disrupt the brewing process and cause the lights to flash. Contact a qualified technician for repairs or replacement if you suspect a brewing unit issue.
5. Overheating Protection
Espresso machines are equipped with overheating protection mechanisms. If the machine overheats, it will automatically shut off and the lights will flash as a safety measure. Allow the machine to cool down before attempting to use it again.
6. Electrical Malfunction
Electrical malfunctions, such as loose wiring or a faulty circuit board, can also cause flashing lights. If you suspect an electrical issue, consult a qualified electrician for assistance.
7. Firmware Update Required
In some cases, flashing lights may indicate the need for a firmware update. Check with the manufacturer’s website to see if any firmware updates are available for your espresso machine model.
