NOTE: Possible Causes/Tests must be performed in the sequence show for each problem.
WON’T POWER UP
(buttons do not respond
when pressed)
1. Verify that the SWASH™ system is plugged into a working outlet and that there are no blown fuses or
tripped circuit breakers.
2. Verify that the plug does not have two adapters attached to it.
3. Unplug the SWASH™ system or disconnect the power.
4. Reconnect the power.
5. Check the voltage available (120V) at the ACU terminals (CON2-P12 and CON1-P9). If there is voltage,
go to step 10.
6. If there is no voltage at the ACU, disconnect the power cord from the harness and check if there is
voltage (120V) at the connector that plugs into the harness. If there is voltage at the power cord
connector, go to step 8.
7. Replace the power cord if there is no voltage at the connector.
8. Check the continuity between power cord connector terminal 1 on the harness and CON2-P12. Check
the continuity between terminal 2 and CON1-P9.
9. Replace the harness if there is no continuity in any line.
10. Check that there is 5V DC between pin 2 and pin 3 at connector P19 inside the ACU.
11. If there is no voltage between pin 2 and pin 3 at connector P19 on the ACU, replace the ACU.
12. If there is voltage between pin 2 and pin 3 at connector P19 on the ACU, replace the UI.
WON’T START A CYCLE 1. Verify that there is a cup inside the SWASH™ system.
2. Check if the orange LED on the UI is flashing at a rate of 3 Hz.
3. If the orange LED is flashing and a cup is inserted in the SWASH™ system, verify that the piercing
mechanism is functioning properly.
4. Verify that the pump harness is connected to the ACU at connector J1-10.
5. Disconnect the pump, attempt to start a cycle, and verify that there is voltage at the pump terminals
on the harness during the dispensing phase.
6. If there is no voltage at the pump terminals on the harness, check the continuity of the harness
between the pump and the ACU. If continuity is OK, replace the ACU.
WON’T DISPENSE 1. Verify that the cup inside the SWASH™ system is new.
2. Disconnect the pump, attempt to start a cycle, and verify that there is voltage at the pump terminals
on the harness during the dispensing phase. If there is voltage, go to step 4.
3. If there is no voltage at the pump terminals on the harness, check the continuity of the harness
between the pump and the ACU. If continuity is OK, replace the ACU.
4. If there is voltage at the pump terminals on the harness, replace the pump.

WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Failure to do so can result in death or
electrical shock.
Replace all parts and panels before operating.
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.
