Fill the water reservoir

Make sure the water reservoir is empty and fill it until its full. Moreover, you should keep it off while following these steps. You can pour two carafes of descaling solution in the coffee maker and let it sit for some time. 

Start the brewing cycle 

Remove the used paper filter if you have one in it. Furthermore, start the brewing cycle as you do while brewing coffee. Also, do not forget to place the carafe beneath the coffee outlet. After sometime you will see the water dripping into the carafe. Even after it has stopped, keep the carafe idle for some time so if there is any scaling inside the carafe, it will go away. 

Run water through the coffee maker 

Throw away the water from the carafe and fill the water reservoir again with normal water and once again start a brewing cycle so you will get rid of the strong vinegar odor and chemicals inside.

Similarly, do this with the carafe. After following these steps your coffee maker would start working as new and there will be no bitter taste or slow pour.
