There are various reasons why a coffee machine may not prepare the beans properly. One possible reason could be a problem with the grind size. The ideal grind for coffee machines is medium-fine, and if it is too coarse or too fine, it can prevent the machine from extracting the aroma from the beans properly. If you are having problems with your coffee machine, try changing the grind size and see if that helps. Another possible cause could be that the coffee machine has too little water. This can happen if you have used too much coffee compared to the amount of water in the water reservoir. In this case, you should empty the reservoir and fill it with fresh water before trying again. Finally, it is possible that the filter of the coffee machine is clogged with coffee grounds. In this case, you will need to manually clean the filter before using the coffee machine again. These are just some of the possible reasons why your coffee machine is not brewing coffee beans properly.
If this does not solve the problem, the grinder pivot may need to be adjusted. This is a small piece of metal that helps to adjust the size of the coffee grounds. If it is set too wide, grinding problems can occur. To adjust the pivot properly, you will need a flat screwdriver and an adjustable wrench.
Finally, if none of these steps work, you may need to replace the grinder altogether. Depending on the model, this can be a fairly simple process. Be sure to check your machine's manual to find out how to do it safely and correctly. If the problem persists, it may be time to seek professional help.
In any case, it is important to maintain your coffee machine regularly to ensure optimal performance and to avoid any future problems. Cleaning the filter regularly, replacing worn parts and ensuring that all connections are secure are just a few simple ways to keep your coffee machine running smoothly. By taking care of your coffee machine, you can enjoy delicious coffee for years to come.
