Publication number: 20140053873Abstract: A method of detecting a clogged or partially clogged wash arm in a warewash machine involves the steps of: monitoring a rotational speed of the wash arm during a washing step of aware cleaning cycle or operation; and comparing the monitored rotation speed to a set threshold speed and, if the monitored rotational speed falls below the set threshold speed, triggering an operator alert to advise the machine operator to check the wash arm. An advantageous sensor arrangement associated with a wash arm manifold is also provided.Type: ApplicationFiled: March 14, 2013Publication date: February 27, 2014Inventors: Michael T.

Patent number: 8252121Abstract: A warewasher for washing wares includes a chamber for receiving wares. The chamber has an associated liquid delivery system for spraying liquid onto wares within the chamber. A tank collects the sprayed liquid. A liquid recirculation system moves liquid from the tank back to the liquid delivery system. A drain system is located within the tank. The drain system includes a well, a liquid recirculation system inlet within the well and a drain opening within the well. A drain control assembly includes a drain stopper member and a strainer connected with the drain stopper member. When the drain stopper member is positioned to block flow through the drain opening, the strainer is positioned to block passage of tableware into the well. The strainer is mounted for sliding movement along a length of the drain stopper member enabling, when the drain stopper member is raised slightly to permit flow out of the drain opening, the strainer to remain in position to block passage of tableware into the well.Type: GrantFiled: November 28, 2007Date of Patent: August 28, 2012Assignee: Premark FEG L.L.C.Inventors: Brian A.

Patent number: 6178625Abstract: A longitudinal warewasher section, of a warewasher assembly having a plurality of warewasher sections mounted end-to-end, includes a frame and a control box pivotally mounted thereto, where the control box is pivotable from a compact, shipping orientation to an installation or operating orientation. The control box preferably includes electrical controls that have been pre-wired to the electrical and/or mechanical components of the warewasher section. When in the shipping position, the rear face of the control box lies substantially flush against a lateral end of the frame and the side face of the control box is substantially flush with the longitudinal front wall of the frame such that the control box faces outwardly from the lateral end of the frame. In this orientation, the control box does not add to the total lateral width of the warewasher section.Type: GrantFiled: September 4, 1998Date of Patent: January 30, 2001Assignee: Premark FEG L.L.C.Inventors: Michael T.
