IF THE LIQUID LEVEL SENSORS ARE NOT CLEANED REGULARLY, THE
MACHINE MAY FAIL TO OPERATE; OR IT MAY BE POSSIBLE TO RUN IT
WITHOUT WATER, WHICH WILL CAUSE SERIOUS DAMAGE TO THE UNIT.
DAILY
Clean the liquid level sensors that are located on the side walls of the wash and
sanitizer tanks. They are the white plastic discs with metal centers. Clean the
sensor faces thoroughly. If cleaned regularly, a washcloth and soapy water are all
that is required.
IMPORTANT: TURN OFF THE POWER TO THE UNIT AT THE MAIN BREAKER
PRIOR TO PERFORMING THE FOLLOWING TASK!
MONTHLY
Clean the pump motor fan shroud with a damp, soapy cloth. The motor shroud is
the “vented” cover located at the end of the motor (closest to the control panel).
This will prevent grease and dust from accumulating in the cover’s openings,
which can obstruct the airflow that cools the motor.
Note: The motor bearings are permanently sealed and do not need to be greased.

3 SM-PS-100
Cleaning The Motor Fan Shroud
The motor fan shroud is the “vented” cover located at the end of the motor closest
to the control panel. Shut off the electrical supply at the electrical circuit breaker
located in the wall mounted enclosure. Clean the pump motor fan shroud with a
stiff bristle brush and a vacuum. If a brush and vacuum are unavailable, clean
the shroud with a damp, soapy cloth. This will prevent grease and dust from
accumulating in the openings of the cover and obstructing the airflow that cools
the motor. Note: The motor bearings are permanently sealed and do not need to
be greased.
Cleaning The Heating Element
Shut off the electrical supply at the system’s electrical circuit breaker located in
the wall mounted enclosure. Remove the cover plate located in the slanted surface
of the back wall of the wash tank. Remove debris that has collected in and around
the heating element. Install the cover plate when cleaning is completed. The cover
plate must be installed after cleaning to prevent foreign objects from entering the
pump suction and causing damage to the pump.
AS NEEDED
De-Lime The Wash Tank
Select a de-liming agent that is safe for plastics and stainless steel sinks. Follow
the instructions on the package for mixing and fill the tank with water. Turn on the
pump motor to circulate the mixture in the tank and pump manifolds.

is present the transformer is operating correctly.
3 Amp Fuse The fuse will blow if there is a current leak in the 24V circuit.
Check the transformer for proper voltage across the fuse.
If fuse is blown examine wiring for any loose connections,
replace fuse and attempt to start the sink.
WASH PUMP WILL NOT OPERATE: HEATED WASH SINK CONTROLS
Heated controls have similar components to sinks without wash tank heaters
with the exception of the following:
Possible Cause Solution
Start button
depressed and the
safety contactor does
not pull in.
1. Check if water temperature is over 130°F if so drain water
and fill sink with cold water see if contactor pulls in.
2. Check Heater High limit Thermal Snap Disc for continuity
(unplug with water below 130°F.
Start button pressed, contactor pulls in: Check for voltage on
T1, T2, and T3 this should match the unit’s serial voltage. If not
replace the contactor.
MOTOR STARTS, BUT MAKES NOISE
Possible Cause Solution
Debris lodged in the
pump housing.
1. Turn the power off to the machine at the circuit breaker in
the wall mounted electrical enclosure

4 SM-PS-100
THE CONTROL CIRCUIT FUSE “BLOWS” WHEN THE POWER IS TURNED ON
Possible Cause Solution
The coil in the
contactor or
contactors is
drawing too much
current. (Note only
when Start button is
depressed)
1. Turn off the power to the machine at the circuit breaker in
the wall mounted electrical enclosure.
2. Replace the 3 Amp fuse.
3. Check the Motor Contactor, Safety Contactor, and Operating
contactor independently for proper function. (This can be done
by disconnecting the wires leading to the A1 and A2 terminals
on all contactors.)
Defective Water level
Board
1. Turn off the power to the machine at the circuit breaker in
the wall mounted electrical enclosure.
2. Replace the 3 amp fuse.
3. Disconnect the NO connector.
4. You should see a red LED indicator lit on the water level
board when water is filled above the sensor (Note the sensor
has to be clean and the green/white wire needs to be properly
secured in the rear of the sensor).
5. Check for voltage across L1 and L2 it should be between
20-28V. There should also be 20-28V to the NO circuit.
6. If the fuse does not blow with the NO connector
disconnected check wiring for shorts to ground.
7. If the fuse “blows” when switched on replace the Water
level board.
The transformer is
applying to much or
too little voltage.
The Transformer should output between 20-28V if this voltage
is present the transformer is operating correctly. If voltage is
incorrect replace transformer.
THE CONTROL CIRCUIT FUSE “BLOWS” WHEN THE DISPENSER BUTTONS
ARE DEPRESSED
Possible Cause Solution
Short to ground
in the chemical
dispenser box.
1. Turn off the power to the machine at the circuit breaker in
the wall mounted electrical enclosure.
2. Replace the 3 Amp fuse.
3. Remove the Black/Yellow harness in the rear of the control
check all pins against ground.
4. If no shorts to ground are apparent you will have to replace
the solid state timer.
Dispenser pump
motor is defective.
Motor does not turn when button is depressed, and 24V
DC voltage is detected at the motor terminals. Replace the
dispense pump motor.
THE WATER LEVEL, BOARD LED INDICATES THAT THE TANK IS EMPTY
WHEN IT IS ACTUALLY FULL
Possible Cause Solution
The sensor is coated
with debris.
Clean the face of the sensor with a washcloth and soapy
water.
The wire connected
to the sensor is loose
or broken.
Check the nut that secures the wire to the sensor on the
outside of the tank.
THE WATER GETS TOO HOT AND STOPS THE MACHINE
Possible Cause Solution
Incorrect soap
is creating too
much foam. (Foam
causes excess heat
by reducing the
efficiency of the
pump and it insulates
the top of the tank
which holds in heat).
Change the wash solution and use a low foaming soap
designed for continuous ware washing or reduce the quantity
of low foaming soap that is added to the water.
The Operational
contactor coil is
stuck open and is
passing current to
the heater when it
should be off.
1. Turn off the power to the machine at the circuit breaker in
the wall mounted electrical enclosure.
2. Unplug the quick connect wires from the operational
contactor coil. Check for continuity across all legs of the
contactor while the unit is off. If any leg is closed replace the
contactor.
3. Fill Wash sink with hot water over 115°F. Using a Multimeter
check for continuity, if open replace the Heater Operating
Thermal Snap Disc.
THE CHEMICAL DISPENSER PUMP RUNS, BUT DOES NOT PUMP THE
CHEMICAL
Possible Cause Solution
The hose has
been punctured or
ruptured.
Replace the defective hose with a new hose.
The fitting has
not been screwed
onto the chemical
container properly.
1. Unscrew the fitting from the container; check the threads
and face of the fittings for damage.
2. Carefully screw the fitting back onto the container so that
the fitting seats properly against the container opening.
CONTROL PANEL COMPONETS
PUMP CONTACTOR
The pump contactor feeds high voltage power to the pump motor. This contactor
has a 24V latching coil across terminals A1 andA2. If the contactor is malfunctioning
it would affect the wash pump motor. Begin checking the contactor as follows:
TURN POWER OFF AT BREAKER PANEL.
If there is 24V across the coil (terminals A1 and A2) and the contactor does not pull
in, the contactor is defective.
Remove the wires from terminals T1, T2, and T3 (if 3 phase) on the thermal
overload. Push the contactor closed manually and check for continuity across
pump contactor terminals L1 and T1, L2 and T2, L3 and T3. If there is no continuity
present on any of these, the contactor is defective.
THERMAL OVERLOAD
The thermal overload protects the Pump motor from overamp conditions. The blue
reset button should be in the down position (automatic reset). The dial should
be set at 115% of the motors FLA denoted on the serial tag. The trip indicator
is located between the dial and the symbol“LR2”. The thermal overload can be
checked as follows:
TURN POWER OFF AT BREAKER PANEL.
Remove the wires from terminals 95 and 96. Make sure the thermal overload is
not tripped. If the thermal overload is tripped, reset it. If the thermal overload has
tripped recently, you may have to wait several minutes for it to cool down before
it will reset.
Check for continuity across terminals 95 and 96. If no continuity, the thermal
overload is defective or the reset is tripped. Make sure the T1, T2, and T3 terminals
on the pump contactor are tight. Remove the wires from terminal T1 and T3 on the
thermal overload. Check for continuity across T1 on the pump contactor and T1 on
the overload, T2 on the pump contactor and T2 on the overload, T3 on the pump
contactor and T3 on the overload. If no continuity on any of these, the overload is
defective.

based on water temperature. The switch will be closed if water temperature is
below 115°F +/- 5°F and will automatically reset at 104°F +/- 5°F. Unplug 14
pin connector and check sockets 7 and 8 for a short against ground. The snap
disc should read less than 1 ohm when closed. Replace if open when water
temperature is under 115°F. The sensor is located in the sensor pad on the rear of
the unit sink see the disassembly section for details on how to remove.
MOTOR THERMOSTAT (MTR-TSAT)
The Motor Thermodisc is a protection device only the motor. If the temperature
of the motor reaches 180°F, the disc opens, cutting off power to the contactors,
and power to the motor. Check for a short to ground between the 2 brown quick
connect wires. If open and the motor is not hot motor will need to be replaced as
the thermodisc cannot be replaced.
TRANSFORMER
The Transformer reduces the incoming power supply voltage to 24 volts. The
transformer source power should match the units serial tag. Per the wiring
diagram one leg should be placed into the COM tab the correct voltage will
need to be selected between the 208 and 240 volt models. The 480 volt model
transformer will have a single tab labeled as “480”. The output voltage can be
checked at the 3 amp fuse it should read between 20-28V.
On single phase heated models the 208/240V to 24V transformer comes with a
4 amp resetable internal breaker. If this breaker trips and the 3 Amp inline fuse is
not open there is an internal fault with the transformer. If the 3 amp fuse is open
there is a defective component or a short in the 24V circuit, check all connections.
HEATER ELEMENT
The heater in a Power Soak sink is rated at 7000 watts. It includes 3 individual
2333 watt heater elements.
To check operations of the heat element, first turn the power off at the breaker.
Disconnect wires from the Heater contactor, check each heater lead to ground for
short. If no short is found refer to the list below to check the heater for internal
faults.

The heater should be within a 10% variance of the value of the chart.
If the reading varies significantly from the chart above, the heater may be defective,
or there may be a broken wire or loose connection. Electrically, the Heater is three
separate elements, each of 2333 watts. When replacing, note how the existing
Heater is wired, and refer to the schematic when wiring a new heater.
SAFETY CONTACTOR & HEATER CONTACTOR (WASH TANK HEAT MODELS
ONLY)
The Safety contactor feeds the pump motor contactor and the Heater contactor
with the source high voltage. It contains a 24V coil that pulls in once the start
button is depressed. The only condition where the safety contactor will not pull in
is when water temperature is above 135°F the high limit snap disc has failed or
the pump motor thermostat has tripped.
The Heater contactor has a 24V coil that only pulls in when the start button is
depressed and the water temperature is below 115°F. The heater contactor coil
is connected to the operational temperature snap disc to regulate the wash tank
temperature from 104°F-115°F +/-5°F. The heater contactor is connected to the
heater element based on the supplied wiring diagram.
To check the heater and safety contactors do the following:
TURN POWER OFF AT BREAKER PANEL.
Unplug all connections manually depress the coil, check for continuity across L1
to T1, L2 to T2, and L3 to T3 if no continuity is present the contactor is defective. If
the contactor presents continuity plug in all connections and proceed. Fill the wash
tank to fill line, Press the green start button and examine the following:
Use a multimeter to check coil terminals A1 and A2 for 20-28V across the coil. If
voltage is recorded, and the contactor is not pulling in, the contactor is defective
replace as necessary.
If no coil voltage is read on a multimeter check Thermal snap disc’s for proper
function.
PUSH ON / PUSH OFF START AND STOP BUTTONS
TURN POWER OFF AT BREAKER PANEL.
The start and stop buttons are connected to the 24V circuits that switches all
components on. The start and stop buttons can be checked as follows:
The stop button should have continuity at rest and no continuity when pushed in.
The start button should have no continuity at rest and continuity when pushed in.
Remove the wires before checking for continuity, if either switch does not have the
proper continuity replace the button.
LIQUID LEVEL CONTROL AND SENSOR
The liquid level control sends a trickle current (1/1000 amp) out terminal LCO
to the liquid level sensor. If there is water in the wash sink, the current passes
through it to the wash sink wall and back to the liquid level sensor to terminal GND.
After the circuit is complete, the relay in the liquid level control will close sending
current to operate the various components in the control panel. If the red indicator
light is “on” the liquid level control senses water. A 10 second time delay is timed
after the control has not sensed water. The purpose of this delay is to prevent rapid
cycling of the relay should the water rise and fall below the sensor while the sink
is filling or running. At the end of the time delay, the relay in the liquid level control
will open to stop the pump.
The sensor that is located on the top of the sink is the only sensor used. Check the
rear of the sensor to ensure proper connection of the white and green wire.
HEATER HIGH LIMIT THERMAL SNAP DISC / 130°F
The Heater Thermodisc is a protection device. The Hi-limit Bi-metallic snap disc
switch for water temperature (switch must be closed if water temperature is below
130°F +/- 5°F). Entire unit will not function until water is drained and colder water
is introduced. Unplug 14 pin connector and check sockets 9 and 10 for a short to
ground. The snap disc should read less than 1 ohm when closed. Replace if open
with water temperature under 130°F. The sensor is located in the sensor pad on
the rear of the unit sink see sensor pad on how to remove.
HEATER OPERATING THERMAL SNAP DISC / 115°F
The operating Thermal snap disk controls the on/off cycle of the sinks heater

seal bellows are seated against sleeve shoulder and carbon seal face is not
scratched or chipped.
5. Slide the shaft sleeve onto the motor shaft and install the O-ring on the groove
of the sleeve. Using lube or grease on the O-ring will help hold the ring in place
temporarily until the impeller is secured.
6. Install the key on the motor shaft and place the impeller on the motor shaft
engaging the key.
7. Put the gasket on the washer head cap screw.

12 SM-PS-100
8. Install the impeller cap screw by holding the impeller, push the impeller back
against the sleeve and the other hand tighten the screw to 23-ft lbs. of torque.

should be at the bottom.
10. Install (3) nuts on the studs and tighten to 23-ft.lbs.
11. Reinstall the control box using the (6) hex bolts tighten to 63 in-lbs.
12. Plug in the motor wires to the thermal overload in the control.
13. Reconnect the black/yellow cable to the rear of the control.
14. Turn power on at the breaker panel.
15. Fill the wash sink up with water.
16. Start the wash sequence and inspect for proper function.
HEATING ELEMENT
Disassembly
Tools Needed:
•Phillips screwdriver
•Flat head screwdriver
•7/16” socket and ratcheting wrench
•Fishing tape or string (optional)
•Duct tape (optional)
1. Drain the wash sink.
2. Remove the cover by removing (4) 7/16” acorn nuts from the outside bottom
surface of the wash tank
3. Remove the (4) flat head screws on the cover plate inside the wash tank on the
slanted surface of the back wall.
4. Remove the (4) 7/16” nuts from the heater element mounting plate on the
bottom side of the wash tank.
5. Remove the (4) Phillips head screws on the control panel and open the control
panel.
NOTE: Note how the existing Heater is wired to the contactor (it is helpful
to take a picture or make a sketch of the wire connections).
6. Disconnect the wiring to the heater contactor.
NOTE: To assist with reassembly, connect fishing tape or string to the
heater wires.
7. Remove the heating element from the back wall of the sink by maneuvering
through the Heater access plate in the wash sink while pulling the element
wires through the conduit.
8. Remove the gasket to the heating element.
Inspection
Examine the gasket for cracks or tears. Examine the wires extending out of the
base of the element. The insulation on the wires must not be burned, cracked or
missing. The connectors on the end of the wire must be free of corrosion, crimped
tight on the wire and no broken wires. Clean debris off the heating element coils
and inspect the coils for cracks or burned areas on the surface of the coil. Replace
any defective part with a new part.
Assembly
1. Place the gasket on the bottom surface of the heating element mounting plate.
2. Insert the heating element though the opening in the back wall of the wash
tank.
3. Push the wires through the center opening and align the studs with the
mounting holes on the bottom surface of the tank.
4. Install the (4) 7/16” nuts on outside surface of the tank to secure the heating
element to the bottom of the tank.

CHEMICAL DISPENSER (OPTIONAL)
A chemical dispenser can be purchased from Power Soak. The dispenser that is
purchased from Power Soak will be mounted under the drain board on the “clean
side” of the sink assembly and contain two or three pumps, depending on the
application. The wiring harness has connections to supply power and operating
signals to the chemical dispenser pumps. Malfunctions in the chemical dispenser
can lower the operating voltage of the PS-100 to levels that are unacceptable and
will cause problems with the operation of the PS-100 control system. See the
chemical dispenser literature for more information on the operation and service
of the dispenser.
