Preparing Coffee

Before making your first pot of delicious coffee, we recommend rinsing the coffee maker by running one or two cycles with water only, without ground coffee in the filter basket. This will remove any possible dust which may have settled during shipping.

Be sure that the water chamber is empty. Remove any literature, etc if found in the water chamber.

■The lid of the glass carafe must be properly positioned during the brewing process. The front hooks have to be inside the carafe and the rectangular part of the lid to be pushed down so that it engages with the handle of the glass carafe.

■To release the lid push the rectangular part of the lid upwards.

■Make sure that the swivel filter is closed properly during the brewing process. Push in firmly until the handle touches the side of the coffee maker and filter “clicks“ into place.

■Caution: If the swivel filter is not closed in properly the “Stop ‘N Serve” can not function. This may cause hot water or hot coffee to overflow.

■The “Stop ‘N Serve” mechanism is opened as long as the glass carafe is inserted into the machine and sits properly on the warming plate and the swivel filter is closed properly. When brewing coffee make sure the glass carafe is in place (see Stop ‘N Serve section).
