WHAT'S NEW
√
QUIETER OPERATION - Possible in part because only one spray arm operates at a time. Since only one
spray arm is in motion at a time, a smaller, quieter, motor can be used to recirculate the water.
√
USES LESS WATER - Since only one spray arm is in operation at a time, less water is needed in the sump
than previous dishwashers. (EXAMPLE: 1.2 gal./ fill vs. 2.3 gal./ fill on previous Ultra-Style models.)
√
USES LESS DETERGENT - Because less water is used, less detergent is required. EXAMPLE: 27 ml.
vs. 47 ml. on previous Ultra-Style models.
√
SEPARATE RECIRCULATE AND DRAIN PUMPS - The recirculate pump operates in one direction only.
A smaller, separate pump is used to drain the water from the sump.
√
FULL FLOW FILTRATION - 100% of the water distributed to the spray arms is continually filtered.
√
GLASS TRAP - Removes any particles which are too large to pass through the pump.
√
NEW DETERGENT AND RINSE AID DISPENSER - The detergent dispenser and rinse aid dispenser
are incorporated into a single dispenser that utilizes a single actuator to dispense both products.
√
PTC HEATING ELEMENT - This element is self regulating to provide lower wattages during the dry cycle
than in the wash cycle when it is used to boost the water temperature.
√
VENT VALVE - Closed during water recirculation cycles for quiet operation, but opens during dry cycle
to allow moist air to escape.
√
TEMP ASSURE AND HEAT DELAY THERMISTOR - A single thermistor located beneath the sump
raises the water temperature in the wash and rinse cycles. This is accomplished by the electronic control
stopping the cycle advancement (for a maximum of 10 minutes) until the element has heated the water
to the required temperature.
√
HIGH LIMIT THERMOSTAT - Located on the left rear tub bottom, the high limit thermostat is used to
prevent the tub from overheating in the event of a component failure.
√
FAN ASSISTED DRYING - Some models are fan assisted to speed up the drying process. Although this
concept is not new, the type of fan (squirrel cage) and location (door) are.
√
TURBIDITY SENSOR - Checks to see how dirty water is in the 1st Wash cycle and in the 1st Rinse cycle.
√
RINSE AID DISPENSER - Has a small circuit board which detects when the Rinse Aid Dispenser is low
on Jet Dry. It will display a "LO" in the display window for Display Models Only.
