Coffee machines are complex electronic devices, so it's inevitable that they will experience some minor problems during use. Here are some of the most common coffee machine problems and how to fix them so you can troubleshoot at home.
Problem: Coffee flows too fast
Cause:
- The coffee is too fine.
- The coffee is not tamped tightly enough or there is not enough coffee.
Fix:
- Check the grind size of the coffee. Finely ground coffee will cause the water to flow through too quickly. You can adjust the grind size of the coffee using a coffee grinder.
- Tamp the coffee more tightly. You can use a tamper to tamp the coffee. If you don't have a tamper, you can use a spoon or other flat-surfaced utensil.
Problem: Coffee flows slowly or drips
Cause:
- The coffee is too coarse.
- There is scale buildup in the water reservoir.
- The rubber gasket at the coffee spout is damaged or the coffee was tamped too tightly.
Fix:
- Check the grind size of the coffee. Coarsely ground coffee will cause the water to flow through too slowly. You can adjust the grind size of the coffee using a coffee grinder.
- Clean the water reservoir. The water reservoir is where the hot water is stored before being used to brew coffee. If the water reservoir is dirty, it will cause the water to flow slowly and have a bad taste. You can clean the water reservoir using a descaling solution.
- Replace the rubber gasket at the coffee spout. The rubber gasket at the coffee spout helps create a seal, helping the water to flow evenly. If the rubber gasket is damaged, it will cause the water to flow slowly.
Problem: Coffee spout does not produce any or very little coffee
Cause:
- The rubber gasket at the coffee spout is damaged.
- There is scale buildup in the water reservoir.
- The water supply valve is clogged.
Fix:
- Check the rubber gasket at the coffee spout. If the rubber gasket is damaged, replace it.
- Clean the water reservoir. If the water reservoir is dirty, it will cause the water to flow slowly and have a bad taste. You can clean the water reservoir using a descaling solution.
- Check the water supply valve. If the water supply valve is clogged, clean it or replace it.
Problem: Water temperature is too low
Cause:
- The coffee temperature has not been set correctly.
- There is scale buildup in the water reservoir.
- The pressure release valve is faulty.
Fix:
- Check the coffee temperature setting. The ideal coffee temperature for espresso is 90 to 96 degrees Celsius.
- Clean the water reservoir. If the water reservoir is dirty, it will cause the water temperature to be lower. You can clean the water reservoir using a descaling solution.
- Check the pressure release valve. If the pressure release valve is faulty, it will prevent the water in the boiler from being heated to a high temperature.
In addition to these common problems, there are other problems that can occur with coffee machines, such as:
- The coffee machine does not turn on.
- The coffee machine makes strange noises.
- The coffee machine leaks water.
If you experience any of these problems, you should contact a warranty center or coffee machine repair service for assistance.
