Delonghi Espresso Machine: Flowing Frustrations Solved In Minutes

A malfunctioning DeLonghi espresso machine, particularly when it ceases to dispense coffee, can be a frustrating experience. This guide will delve into the potential causes and provide comprehensive troubleshooting steps to resolve the issue of your DeLonghi espresso machine not flowing.

Common Causes of a DeLonghi Espresso Machine Not Flowing

• Clogged Filter Basket: Coffee grounds can accumulate in the filter basket, obstructing the flow of water.
• Air Lock in the System: Air pockets in the machine’s water lines can prevent water from reaching the filter basket.
• Scale Buildup: Mineral deposits from hard water can accumulate on the machine’s components, restricting water flow.
• Faulty Pump: The pump is responsible for delivering water to the filter basket. If it malfunctioned, it could impede the flow of coffee.
• Blocked Outlet Valve: The outlet valve allows coffee to exit the filter basket. If it becomes clogged, it can prevent the flow of espresso.
• Insufficient Water Pressure: Low water pressure can hinder the flow of water through the machine.
