PUMP MOTOR - TEST
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
NOTE:
The pump motor for all machines is rated at 2
H.P. and has thermal overload protection.
1.
Remove FRONT COVER.
2.
Open control door.
3.
Apply power and measure incoming voltage
verifying it meets machine requirements.
4.
Turn machine on and take an amperage reading
of one of the tank heater leads connected to
contactor (2CON).

NOTE:
Current consumption for a normally operating
pump and motor assembly will be less than the
amperage values listed.
5.
If motor current exceeds those values listed in the
table, inspect pump for blockage causing a
locked-rotor condition.
A.
If blockage is not present, replace motor.
6.
If current in one phase of a three phase motor is
low or missing, also inspect incoming line
service, contactor 1CON and other related
circuitry to missing phase.
THERMISTOR - TEST 1QTM, 2QTM
& 3QTM
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
NOTE:
The temperature/resistance characteristics
are the same for all the thermistors used in SD3.
NOTE:
The resistance of each thermistor can be
measured by removing the plug connected to J2 on
the control board.
1.
Remove FRONT COVER.
2.
Open control door.
Quick Check Using Service Diagnostics
1.
Enter Service Diagnostics mode.
A.
Apply power. With machine off, press and
hold the PROG and SELECT switches on
control board and press and release the ON
key on the switch membrane keypad.
B.
Continue to hold in on the PROG and
SELECT switches until display shows [ 88 ]
then release both switches.
NOTE:
XXX represents the actual water temperature.
C.
Press the SELECT switch repeatedly until
[ WASH XXX°F (°C) ] which is tank water
temperature.
D.
Press the SELECT switch once to display
[ XXX°F (°C) RINSE ] which is rinse water
temperature.
E.
Press the SELECT switch once to display
[ WASH XXX°F (°C) RINSE ] which is
booster water temperature.
Measuring Thermistor Resistance
1.
Disconnect the plug from J2 on the control board.
