Debris clogging the drain and the impeller blade can prevent the sump area in the bottom of the dishwasher from draining A malfunctioning check valve prevents water from backing up into the dishwasher sump through the drain hose. Water may drain out of the dishwasher while the drain pump runs...
It wasn't. At that time I didn't understand the "air gap" piece and just figured it was a safety device as it has a hole in it for water to come out, if the garbage disposal was clogged and the water couldn't drain through it. I don't know why it took me so long ...
The vent assembly mounted in the door on many models can be a source for leaks, either through failure of the vent diaphragm valve, or failure of the gasket which seals the vent assembly to the inner skin of the door. These leaks will usually show up at the bottom edge of the door. ...
6. A dishwasher as defined in claim 1, further comprising: a bulkhead (322) between the drain pump (32) and the sump (30); a fluid passageway (402) defined through the bulkhead (322); an air vent passageway (408) defined through the bulkhead (322); and an air vent blocker (412) ...
which deliver their controlled output through the Y fitting 163 and a suitable connecting conduit (163a) to the standard air gap generally indicated at 163b. This unit supplies the machine initially with water. The safety device 164 is capable of emergency draining the sump 144 via the conduit...
a receptacle located behind said wall and communicating with the dishwasher interior through a vent in said wall, an open top container for holding a charge of detergent mounted within said chamber, a water outlet nozzle positioned above the open top of said container, and a supply valve whi...
As warm air is introduced into the moist air conduit 64, and thus into the treating chamber 20, excess air in the treating chamber 20 may be exhausted via the vent 104 of the regeneration system 100 or through other openings in the treating chamber 20. The efficiency of the condensation ...
An example of such an outlet has been illustrated as a vent 94, which may exhaust the supplied air from the treating chamber 16. The vent 94 may be fluidly coupled to an outlet duct (not shown), which vents into the interior of the door 28, allowing air to escape through the various...
3, the controller 22 can be coupled with the heater 92 for heating the wash liquid during a cycle of operation, the drain pump 61 for draining liquid from the treating chamber 16, and the recirculation pump 53 for recirculating the wash liquid during the cycle of operation. The controller ...
draining water and motors for driving the pumps. This construction of course requires pipings between the pump and the spray arm thus complicating the construction and increasing the cost of manufacturing. Circulation of the water through the tub and spray arm causes the small jet orifices to be...
