Assuming you have a Black and Decker coffee maker that is not working, here are some potential solutions:
First, check to make sure the coffee maker is plugged in. If it is plugged in, then check to see if there is power going to the outlet by plugging in another appliance. If there is no power going to the outlet, then you will need to reset the circuit breaker or replace the fuse.
Next, check the water reservoir. Make sure that it is full and properly seated on the coffee maker. If it is not full, then add water until it reaches the fill line. If the reservoir is empty, then your coffee maker will not be able to brew coffee.
If your coffee maker still isn't working, then contact Black and Decker customer service for further assistance.
