- Ensure that the coffee machine is plugged into a functional outlet. You can check this by plugging in another device.
Step 5: Eliminate Air Locks
- To release an air lock, you can try running plain water through the system without coffee grounds. This will often dislodge any trapped air and restore flow.
- Turning the machine on and off a few times can also help relive any pressure build-up caused by an airlock.
Preventative Maintenance Tips
Once you’ve fixed the issue, you’ll want to ensure it doesn’t happen again. Regular maintenance can extend the life of your coffee machine and keep it running smoothly.
1. Regular Descaling
Schedule regular descaling based on how often you use your coffee machine and the hardness of your water. If you’re in a location with hard water, descaling every month is wise.
2. Use Filtered Water
Using filtered water can significantly reduce mineral buildup in your coffee machine. This can help prolong your machine’s life and enhance the taste of your coffee.
3. Clean Removable Parts
After each brewing cycle, clean the removable parts of your coffee machine. This includes the filter basket, drip tray, and water reservoir. Regular cleaning can prevent residue buildup that can lead to clogs.
4. Follow the Manufacturer’s Instructions
Every coffee machine is different; therefore, following the manufacturer’s guidelines for use and maintenance is essential. This includes recommended cleaning schedules and using the correct types of coffee and water.
When to Call a Professional
While many coffee machine repairs can be performed by the owner, some issues might require professional assistance. Consider calling a technician if you encounter any of the following:
1. Persistent Pump Issues
If you’ve gone through the troubleshooting steps and the pump still isn’t working, it may be on its last legs and require replacement.
