A warewasher for washing wares including a housing defining an internal space with at least one spray zone for washing wares. The housing includes an opening defined in part by a lower shelf. A liquid delivery system provides a spray of liquid within the spray zone. An access door has a vertically hinged connection to the housing to provide an open configuration that allows user access to the spray zone and a closed configuration that inhibits user access to the spray zone. The access door includes a threshold seal member at the bottom of the access door. The threshold seal member includes a lower sealing portion that mates with an upper surface of the shelf to provide a lower seal extending laterally along a width of the access door, and an inner sealing portion that cooperates with an inner edge the shelf to provide an inner seal extending laterally along the width of the access door. The inner seal located nearer the spray zone than the lower seal.
