Why do Espresso and Lungo buttons flash on my DeLonghi Coffee Maker?
- LlhutchinsonAug 3, 2025
If the Espresso and Lungo buttons on your DeLonghi Coffee Maker flash quickly, it could be due to a blocked pump or lack of water, or a blocked or defective flowmeter or flowmeter lead. Check the electrical connections to the PCB power board and replace the pump if necessary. Also, clean and/or replace the flowmeter or flowmeter lead to resolve the issue.
