Glass pots can be very breakable. When washing your coffee maker’s pot, treat the glass gingerly. Some coffee makers may have parts that can be washed in a dishwasher. Check the instructions manual, if you still have it. If you’re unsure if your coffee maker can be washed in the dishwasher, err on the side of caution and hand wash it.
If you don’t have the instructions manual, try looking up your model online. You may be able to find an instructions manual on the Internet.
