inches (55.88 cm) long, and 34 inches (86.36 cm) high. It is compact in
size, yet delivers the performance of larger units. With a low power
®
usage, this product model meets ENERGY STAR
guidelines for
energy efficiency.
The Monogram 18" Built-In Compact Dishwasher has two wash levels,
a HEA VY W ASH cycle, NORMAL W ASH cycle, LIGHT W ASH cycle,
CHINA CRYSTAL cycle, and a RINSE ONLY cycle.

Fill Funnel
The fill funnel is mounted on the left side of the
tub. Its purpose is to provide a method of
supplying water for the wash and rinse cycles.
The air gap prevents the siphoning of wash water
from flowing back into the water supply system,
should the water pressure drop to less than
atmospheric pressure. The fill funnel also allows
air into the tub to permit air flow for dish drying.

Pressure Switch
The pressure switch is located under the tub at
the right front corner . A clear plastic tube, the
pressure switch hose, runs from the float switch,
around the fill funnel, and to the sump.
As the dishwasher basin fills with water, the air
pressure in the pressure switch hose increases.
Normally, the timer regulates the amount of time
the water fill valve remains open. If the water fill
valve remains energized, the overfilling of the
basin increases the air pressure in the pressure
switch hose, causing the pressure switch to open
the circuit to the timer motor and closing the
circuit to the drain pump. The drain pump then
empties the water in the sump.

Drain Pump Assembly
The drain pump assembly is located under the tub
at the right rear corner. The drain pump operates
on 120 V AC and is energized 60 seconds af ter the
wash pump shuts down, to remove any water in
the dishwasher sump. The drain pump forces the
water out the drain line. A check valve flapper on
the drain pump prevents the dirty water from
reentering the sump.

Sump Assembly
The sump assembly consists of the filter
assembly, micro-filter, sump clamping nut, sump
gasket, and sump. The filter assembly prevents
large particles from reaching the micro-filter, and
the micro-filter prevents small particles from
reaching the sump. The filter assembly rests
above the sump and the micro-filter sits above the
sump basin. The clamping nut holds the sump
gasket and sump to the bottom of the dishwasher.
The filter assembly, microfilter, and sump
clamping nut are accessed from inside the
dishwasher. The sump gasket and sump are
located under the tub in front of the motor pump
assembly.

Troubleshooting the T imer
If the timer is suspected of faulty operation, refer
to the Timer Cycle Chart and Timer Strip Circuit
and proceed as follows:
1. Index the timer to the first increment of the
HEA VY W ASH cycle. (This is a drain period
which activates the pump motor.)
2. If the pump motor fails to operate during the
first cycle increment block, check the electric
supply . If there is no electric supply, check the
door latch switch. If there is electric supply,
disconnect electric supply and check the
pump motor component resistance (see
Specifications, page 4).
3. If the pump motor does operate, let the timer
motor advance the timer through the drain
increment to determine if the timer motor and
drive train are fully operative.
4. Let the timer advance or index it forward to the
portion of the cycle in question.
5. If a component controlled by the timer fails to
function, as the timer advances through the
cycle, check for voltage at the timer terminals.
If the voltage is supplied to the component,
check the component resistance (see
Specifications, page 4).

Troubleshooting the Wash Pump Motor
Troubleshooting the W ater Fill V alve
The wash pump motor does not start immediately
when the dishwasher cycle has started. The tub
will begin filling with water and the motor will start
approximately 40 seconds into the fill cycle. If the
motor hums, but will not start, make certain the
pump impeller is free from obstructions and the
motor shaft can turn freely. If the capacitor is
open or shorted, the motor will hum and will not
start. Check for 120 VAC (±10%) at the wash
pump motor terminals. Take the voltage
measurement while "under load" (as the motor is
trying to start). This will eliminate the possibility of
a poor wiring connection. If the 120 V AC (±10%)
is present and the motor will not start, the motor
will have to be replaced.
Wash Pump Motor Strip Circuit

If the water fill valve is suspected of faulty
operation, refer to the strip circuit and proceed as
follows:
1. Disconnect the electric supply from the
dishwasher.
2. Remove screws securing bottom of service
panel.
3. Remove valve electrical leads and, using
ohmmeter, check resistance of solenoid. (See
Specifications, page 4, for correct ohms
reading.)
4. To check for proper mechanical operation of
the water valve, attach a separate 115-volt
grounded power source to the valve terminals
and metal frame of the dishwasher. Turn the
power on for a few seconds and then turn the
power off. If water flow does not stop within 2
seconds after turning the water valve off,
replace the water valve.
No Water To Tub
1. Be sure the main water supply and electric
power are turned on.
2. Remove both the service panel and the
toekick panel.
3. Advance timer to the fill position and latch the
door.
4. Start the dishwasher.
5. Use a voltmeter to check for voltage at the
water fill valve solenoid coil.
6. If voltage is present, disconnect power and
measure resistance of the water fill valve
solenoid coil. (See
Specifications, page 4, for
correct ohms reading.) Replace the water
valve, if it is defective.
7. If the water fill valve is good, check the filter
screen and clean it, if necessary.
8. If there is no voltage present at the water fill
valve solenoid coil, disconnect power and
check continuity through the latch switch,
timer contacts, float switch, and wiring.
Repair wiring, as necessary.
Water Level Too Low
1. T urn on the dishwasher and allow the bottom
of the basin to fill with water . Listen for the
water fill cycle to stop and, when it does, open
the dishwasher door . The water level should
touch the heating element.
– 32 –
Page 33
2. If the water does not touch the heating element, disconnect power, close the door, and
check the incoming water pressure. A minimum incoming water pressure of 20 PSI (138
kPa) is needed to properly fill the dishwasher
basin.
Water Fill Valve Will Not Shut Off
1. T urn on the dishwasher and allow the bottom
of the basin to start filling with water . Disconnect power while the basin is filling. If water
continues to flow, turn of f the water supply and
replace the water fill valve.
2. If the water turns off when power is disconnected, troubleshoot the timer and motor.
Replace the defective part.

Washability Complaints
Hot Water – Ample supply of water at a minimum
temperature of 120 °F (48.9 °C) is necessary. Do
not use dishwasher soon after using clothes
washer or filling bathtub.
Loading - Consult Owner’s Manual on loading
procedures.
Amount of Water – Make sure dishwasher is
level. Check water level, allowing dishwasher to fill
normally for first fill. The water level should beto the heating element. If water level is low,
check for clogged screen and check float switch.
See Water Valve and Float Switch.
Detergent/Rinse Module Leakage – Some
moisture in cup is normal. Detergent must not be
soaking wet, oozing out, and down the inner door
panel. If a leak is detected, check the detergent/
rinse module door lid, latch operation, and gasket
seal. Also see
Detergent/Rinse Module.
Proper Amount of Detergent – Use full
detergent cup of fresh detergent in hard water.
Use only enough detergent to get good wash
performance in soft water.
Rinse Agent – Use rinse agent if spotting or
drying is a problem. A rinse agent will improve the
water sheeting action and drying performance.
Water Valve – See
Water Fill Valve.
Spray Arm – Check to be sure the spray arms
spin freely and jets are not clogged. Check to be
sure the middle spray arm water conduit is
connected properly to the main conduit.
Drying – W ater inlet temperature must be at least
120 °F (48.9 °C) for proper drying. Low water inlet
temperature will prevent proper convection air
movement and increase drying time substantially.
A rinse agent will improve the water sheeting
action and drying performance.
