Filtration: The coarse filter traps large food particles that cannot get past the drain pump. The fine filter collects debris that is automatically rinsed away during each wash. The fine filter and tubular section should be cleaned once or twice a year.

Inside Tub Components – Overflow Cap
Normal Water level
The “overflow drain cap” must be in place to prevent water from leaking inadvertently in to the base pan. Under normal conditions, the soap and water will not get into that area but if conditions were right for an overflow condition, the water level or soap level would be high enough to exit into the base pan, and trip the overflow switch and drain.
Copyright 2010
30
Water Level Check the water level using the spray arm hub. The normal fill will come to approximately the top of the flat raised area as indicated. An “overfill” condition will be recognized closer to the locking lip indicated with the red arrow. Normal Fill = .85 gallon (Total cycle = 5.3 gallons) Overfill = 1.25 gallons
Copyright 2010
31
Water Level – How Does it Work?
Water Inlet Valve
Main Control Board
Flow Meter
Normal Fill: (3.2L / .85 gallon) • Water Valve opens and water passes through flow meter • Flow meter looks for 220 pulses per liter. (appx 1 quart) • 704 pulses indicates proper fill. (220 X 3.2 = 704) • Main Control stops fill. • Flow rate maximum of 1 gallon per minute Fill takes less than 1 minute. (Approximately 45- 52 seconds) Copyright 2010
32
Water Level – What if ? What if: 1) The water pressure is low? i.e. low house pressure, clogged valve, etc. The flow meter utilizes an impeller, with two magnets, driven by water flow. When the flow rate is less than 1/3 liter per minute, the board stops the fill cycle and an error is flagged to the customer. (more on errors later) a) Remember 220 pulses per liter (approx. 1 quart) is normal. (The above scenario happens if there are less than 80 pulses in 60 seconds.) b) 80 pulses are reached but pressure is barely above that amount. Overall fill time reaches 255 seconds but the board did not see 704 total pulses. An error is logged 2) The flow meter failed? i.e. no signal to main control. Water could still enter the machine but the board would not see a signal from flow meter. …..then what happens?
Copyright 2010
33
Water Level – What if, continued ? Introducing the “Pressure Sensor” A pressure sensor is located in a pressure chamber in the bottom well. It measures the pressure which corresponds to the water level in the machine. It functions like any pressure sensor with a diaphragm and air channel with pressure. • Reports pressure reading to board. • Acts like a “safety” device. • If it sees an overfill condition for 5 consecutive seconds (appx 4.7 liters / 1 ¼ gallons) it stops the cycle and turns on the drain pump.
Pressure Sensor Copyright 2010
34
Water Level – Pressure Sensor
The Pressure Sensor also: • Can add a pre-wash under certain conditions (clogged filter < 1vdc reported to control) • Can add water if a bowl has flipped over and catches some of the wash water. • Can add time to drain. (25 seconds to max of 3 minutes) • Works off a 5VDC circuit. Ranges from .5 - 3.5VDC. (.5 = empty 2.8 VDC = normal 3.5 = overfill ; > 4.8 generates an error) Voltages are approximate

Air Gap – Flow meter All dishwashers must have an air gap to prevent back flow. On the side of this machine is an anti-backflow device to prevent dirty water from being siphoned back into the water system, such as if a vacuum develops in the water system. As noted earlier, the flow-meter is mounted inside the air break assembly. The bottom assembly of the dishwasher would have to be removed to access the screw that mounts the air-gap. If the flow meter fails, the machine could be set for “Time Fill” and the flow meter is by-passed. (See “Adjust Water Fill” section in service mode)

Turbidity Sensor - Removal Machines with an “Auto” program have a turbidity sensor that measures how cloudy the water is. The sensor comprises of an LED and phototransistor. Between these two, is the dish water. The less light that reaches the phototransistor, the cloudier the water. The sensor is calibrated during the last rinse of the auto program. At different points during the auto cycle, the output signal from the turbidity sensor provides data used to determine how the program will continue (number of pre-washes, temperature, program time, number of rinses) It only functions in the “Auto” cycle.
If the turbidity sensor fails, the machine assumes the water is “very cloudy”, which results in a longer program time, pre-washes, additional rinses and temperature. The turbidity sensor is located at the bottom edge of the bottom drain.
• Spread tabs on either side and pull sensor straight out Copyright 2010
51
Thermistor - Removal The thermistor is located at the front edge of the bottom drain and detects when the selected water temperature has been reached. If the thermistor is short circuited or detaches from the circuit board, the heater is turned off. Logic: • Water heats 4˚ per minute. If water is not heated 40˚ in 10 minutes, the machine advances out of heat mode. • If temperature reported exceeds 176˚ the unit advances out of heat mode. • No time out as long as water is heating according to logic.
• Press down on tab and turn counterclockwise

To Drain Pump
The drain pump comprises a 30W synchronous motor and a pump component. The direction of rotation is random, making the pump partially self-cleaning. And it can be accessed for cleaning from inside the tub if necessary. Note: The drain pump runs for 6-25 seconds at the beginning of every cycle. The time is dependent upon whether a cycle ended on it’s own, or was stopped by the customer. Copyright 2010
61
EMI Filter • Located up front at power cord inlet • Suppresses interference to ensure that the machine does not interfere with nearby electrical equipment. • Remove with a single T20 screw and slide to the left to release four bottom tabs out of the dishwasher frame. Note wiring positions.

62
Overflow cut-out - Removal
The overflow cut-out system comprises of a float that triggers a micro switch. This switches off the inlet valve electrically and starts the drain pump. The protection remains in place even if the main power switch is turned off or if the door is opened. Remove by pressing the securing tab to the left and pull switch off two support tabs.

Main Control – Programs Flush and (SCS) Super Clean System
Flush and super cleaning cycles are designed to clean the filters, and to sweep debris to the drain. Essentially, the desire is to begin the pre-wash, main wash, and rinses with as little food residue as possible. At the end of a pre-wash, rather than just drain out all of the water, the drain comes on for 2 seconds to drain debris already residing in the sump. Then the circulation pump comes back on for 20 seconds to flush any remaining debris to the drain. Then the unit drains out the rest of the water. The flush will fill with around a ¼ gallon of water. The circulation pump will come on for 2 seconds, then a 5 second pause where the machine does nothing, followed by 2 more seconds of circulation pump. Then the step ends with a drain.
