I. Preliminary Steps
Follow these steps before attempting to service the SCA
Power off and disconnect the SCA from the main power.
Allow the SCA to cool completely.
Attach a hose to the front valve and drain the tank completely.
Always disconnect the SCA from the main power and drain the tank
completely before servicing.
AZ 85284

II. Quick Troubleshooting
The SCA has been designed to allow the end user to resolve most operating problems. When a problem is
encountered, please read through this repair manual. If a resolution is not found in this manual, please
contact technical support.
High Risk of Electrical Shock
Always disconnect the unit from power
before removing any cover!
Problem
Probable
Causes
What to Do
No Power to SCA
Power switch is
not “On”
Press rocker switch on the back of the unit to the “On” position
(LED lit).
Power cord is
not connected to
unit or wall
If the power switch LED is not lit when the power rocker switch
is turned on, check the power cord, and make sure it is pushed
all the way into the receptacle on the system and is securely
connected to a grounded wall socket. Check the power at the
outlet. Check your building circuit breakers, and any power
circuit that the unit is plugged into for a tripped circuit breaker or
blown fuse. Reset or replace the breaker or fuse as required.
Fuse is blown
With the power disconnected, check the continuity of F1, F2
(both mounted to the chassis) and FB1 and FB2 (both on the
PCB).
Thermal Cutoff
Switch (TCO) is
tripped or
defective
A resettable Thermal Switch located on the back wall of the tank
removes power from the SCA if the temperature of the bath
exceeds 90⁰C. Wait for the bath temperature to cool to < 80⁰ C.
Reset TCO, or ohm out TCO (See Check the Continuity of the
Thermal Cutoff Switch Section XII E pg. 44).
PEM Defective
(See Check the Continuity of the PEM Section XII E pg. 45)
AZ 85284

Problem
Probable
Causes
What to Do
Pump will not
start, SCA is
powered up,
display panel is
lit.
Timer has not
been set and
started
The system will only run when the timer is counting down.
Check the timer display on the control panel.
If it is not counting down, press the button. If the time being
displayed is 00:00, then add time and start the system as
described in the User Manual.
Pump is
defective
(See Measure the Pump Motor Resistance Section XII A-3
pg. 27).
Run Capcitor is
defective
(See Test the Pump Motor Run Capacitor Section XII A-5 pg.
30).
PCB is defective
(See Test the Input Voltage to the Pump Motor Section XII A-
4 pg. 28).
Control Panel is
defective
(See Check the Pump Motor Enable Signal Section XII A pg.
27).

Problem
Probable
Causes
What to Do
Warning Indicator
Flashing
High Water
or Low Water
Indicator flashing
Liquid level is
too high or too
low, audible
alarm sounding
Check if the indicator lights are flashing on the right side of the
Display Control Panel. Press the Silence Alarm Button. If either
level indicator is still flashing, add or remove water from the tank.
If the indicator stops flashing, the level sensors are satisfied and
normal operation can resume by pressing the Start Button .
ALWAYS WEAR PROTECTIVE GLOVES AND EYEWEAR
WHEN ADDING OR REMOVING LIQUID FROM THE TANK.
Basket is raised
or lowered too
quickly
If the basket is lowered into or raised out of the cleaning solution
too quickly, the solution does not fill or empty out fast enough to
maintain even water level throughout the tank. This causes a
temporary high or low water level condition. Press the Silence
Alarm Button. If either level indicator is still flashing, add or
remove water from the tank. If the indicator stops flashing, the
level sensors are satisfied and normal operation can resume by
pressing the Start Button .
Float movement
is impeded by
buildup on shaft
Remove float (See How to Remove the Sensor Assembly
Section V-A pg. 13) and inspect. If there is a buildup on the
shaft that inhibits the free up and down motion of the float, clean
off the shaft. A soft scrub pad can be used to remove any
buildup on the shaft. Ensure the float moves freely from the
bottom to the top of the shaft.
Water level
sensor is
defective
(See Water Level Sensor Troubleshooting Section XII D pg.
39).

Audible Alarm
Internal Error
Sensor failure, power supply failure, or pump failure.
(See Error Codes Section XIII A pg. 50).
Error Codes:
*EP = Pump motor current fault
*EH = Heater current fault
ES = 12VDC out of range, power supply error
EO = Over temperature
r1 = Temperature sensor failure
r2 = High level sensor failure
r3 = Low level sensor failure
*Only displayed on the original controllers without the “No Heat”
option
Not Heating,
Over Heating,
Not reaching set
temperature.
Heater elements
have failed
(See Heating Element Troubleshooting Section XII B pg. 32).
Temperature
sensor is
defective
(See Temperature Sensor Troubleshooting Section XII C pg.
36).
Parts take longer
than normal to
dissolve support
material. White
deposits noticeable
on dark-colored
parts.
The cleaning
solution is likely
saturated with
support material.
Drain the tank and add fresh water and cleaning solution as
described in the User Manual. Generally, if using WaterWorks,
when the PH balance of the bath reaches 11.5, the effectiveness
of the dissolution drops dramatically.
Type of cleaning
agent.
If using Eco Works, try switching to Waterworks. Both are sold
by Stratasys resellers. Waterworks is a more efficient cleaning
concentrate.
The flow in the tank
appears less than
normal.
Nozzle not
latched, angle is
wrong, missing
or broke O-Ring.
Remove the nozzle and inspect. The nozzle will not latch
correctly if the O-Ring is not present or is damaged. Ensure the
nozzle is rotated to the correct angle. (See Figure 8, pg. 15).
