Abstract
A sealing arrangement is provided for a dishwasher in which a pump is mounted on a base which can be removed from the dishwasher and a first sealing member is positioned between the base and the sump for removably sealing the base to the sump. A second sealing member is located within the sump for removably sealing an outlet of the pump to an end of a conduit. With such an arrangement the pump base may be mounted to or removed from the sump in a single operation without making any manual fluid connections.
