Frustrated with a DeLonghi Espresso Machine That’s Not Flowing? Here’s How to Fix It Instantly

If your DeLonghi espresso machine is not flowing, it can be a frustrating experience. But don’t worry, this comprehensive guide will help you diagnose and fix the issue quickly and easily.

Common Causes of DeLonghi Espresso Machine Not Flowing

• Clogged Filter Basket: Coffee grounds can accumulate in the filter basket, blocking the flow of water.
• Dirty Portafilter: Residue from coffee oils and milk can build up on the portafilter, impeding the flow of water.
• Scale Buildup: Mineral deposits from hard water can clog the machine’s internal components.
• Faulty Pump: The pump is responsible for pushing water through the machine. If it’s faulty, water won’t flow.
• Air in the System: Air bubbles in the system can prevent water from flowing properly.
• Blockage in the Solenoid Valve: The solenoid valve controls the flow of water to the group head. A blockage in this valve can restrict water flow.
• Damaged Water Line: The water line that connects the machine to the water source can become damaged or kinked, preventing water from reaching the machine.
