Product Instructions / Product Care


This replacement carafe is packaged with 2 adjustable lid inserts with height settings 1 through 6. Setting 1 is the shortest height setting and setting 6 is the tallest height setting. You will need to test the carafe to determine which height setting triggers the “Pause & Serve” feature on your coffee maker. To test the carafe:

1. Fill your coffee maker with 2 cups of water
2. Insert the carafe into the coffeemaker
3. Turn on the coffee maker

If the lid insert has properly activated the “Pause & Serve” feature, water will flow into the carafe. If the water does not flow into the carafe, adjust the height setting and retest until the proper height is achieved. To adjust the height setting:

1. Raise the lid.
2. Remove Insert: Using both thumbs, press the semi-circular tabs on the bottom of the insert upwards and remove insert from the lid.
3. Replace Insert: Place the insert into the lid using a new height setting and press down until it clicks into place; be sure to align the insert number setting with
the lid alignment mark.
4. Repeat steps 2 & 3 until the proper height setting is achieved.
