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).

AZ 85284

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).

Error Code

Displayed

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).

III. Removing Top Cover and Back Panel

A. How to Remove the Back Panel

1. Remove the Back Panel

a. With the SCA unplugged from power, remove the two screws on the top center and bottom

center of the panel.

b. Loosen the remaining six M4 screws around the outside edges.

c. Push up on the back panel and remove.

Figure 1 – Removing the Back Panel

AZ 85284

B. How to Remove the Top Cover

1. Remove the Top Cover

a. With the SCA unplugged from power, remove the J6 display ribbon cable from the PCB.

b. Remove the three M5 screws holding the top cover to the SCA.

c. Carefully remove the cover by pushing lightly on the back of the cover, ensure the J6 ribbon

cable does not snag on any components.
