A coffee machine that drips instead of delivering a steady flow is a common problem that can be caused by limescale, coffee residue, or insufficient maintenance. Luckily, draining the machine and fixing the problem is easier than you think. Follow this step-by-step guide to restore your coffee machine to proper functioning.

Why does the coffee machine dispense drips?

The main causes of slow or drip-like dispensing are:

Limescale buildup: Limescale can clog the machine’s internal pipes, reducing water flow.
Coffee grounds: Ground coffee grounds can build up in the filters and block the passage.
Clogged filter: An overfilled or clogged filter can prevent a smooth flow.
Inefficient pump: If the pump cannot generate enough pressure, the coffee is dispensed in drops.

How to Bleed a Coffee Machine in a Few Steps

Here’s what to do to purge and clean your coffee machine:

1. Turn off and unplug the machine

Before starting any operation, turn off the machine and unplug it from the electrical outlet to ensure maximum safety.

2. Remove and clean removable components

Remove the water tank and wash it thoroughly.
Clean the coffee filter or basket, removing any residue. Use hot water and a soft brush to remove any buildup.
Check that the dispensing nozzles are not clogged: you can use a toothpick or a needle to free them.

3. Descale the machine

Limescale is one of the main causes of slow brewing. Descale the machine using these steps:

Prepare a descaling solution: use a specific product or a mixture of water and white vinegar (1 part vinegar and 2 parts water).
Pour the solution into the tank: fill the tank to the maximum level.
Start the descaling cycle: pass half of the solution through the machine, as if you were making a coffee without putting coffee in the filter.
Let it work: turn off the machine and let it rest for 15-20 minutes.
Rinse: Complete the cycle with the remaining solution, then rinse the tank with clean water and run 2-3 cycles of water only to remove any vinegar or descaler residue.

4. Check and clean the pump

If the problem persists, you may need to check the pump. Consult your machine’s manual to access the pump and make sure it’s not clogged. In some cases, contacting technical support may be helpful.

Preventive maintenance to avoid future problems

To keep your coffee machine in top condition, follow these simple rules:

Clean regularly: Washing removable components after each use helps prevent buildup.
Use filtered water: it reduces limescale formation.
Descale regularly: Run a descaling cycle every 1-2 months, depending on the hardness of your water.
Avoid coffee that is too finely ground: Coffee that is ground too finely can clog the filter.

A drip coffee machine can be easily repaired by following these simple cleaning and maintenance steps. Taking care of your machine not only ensures optimal operation, but also improves the taste of your coffee.
