Modified on Mon, 26 May at 11:23 PM

According to the problem analysis result done by CCA, you can directly begin the subsequent troubleshooting process from the corresponding potential root cause.

1. Blender

STEP 1 - Put the blender cup on the blender and check if the blender can blend typically.

Result 1 - Can blend.
Start "Power" chapter.

Result 2 - Cannot blend.
Start STEP 2.

STEP 2 - Follow the steps in the blender failure troubleshooting guide to fix the blender. Then, test if the cleaning tool can be detected.

Result 1 - Can be detected.
Issue close.
Root cause: The blender fails
Result 2 - Cannot be detected.
Start "Power" chapter.

2. Power

STEP 1 - Reconnect the wires with the electrodes, then verify if the voltage on the electrodes is 24V DC.

Result 1 - The reading is 24V.
Start "Clenaing Tool" chapter.
Result 2 - The reading is not 24V.
Start STEP 2

STEP 2 - Verify that the cleaning tool wire on the control board is securely connected.

Result 1 - Not securely connected.
Start STEP 3.
Result 2 - Securely connected.
Start STEP 4.

STEP 3 - Reconnect the wire to the control board. Then, verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue closed.
Root cause: Wire disconnected.
Result 2 - Cannot be detected.
Start STEP 4.

STEP 4 - Measure the voltage at the cleaning tool wire connector on the control board. The expected reading should be 24V DC.

Result 1 - The reading is 24V.
Start "Clenaing Tool" chapter.
Result 2 - The reading is not 24V.
Start STEP 5.

1-3-3-11 - Replace the control board (see SOP here). Then, verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue close.
Root cause: The control board fails.
Result 2 - Cannot be detected.
Start "Clenaing Tool" chapter.

3. Cleaning Tool

STEP 1 - Verify if the spring-loaded pins under the cleaning tool can rebound properly and are well-connected with the cleaning tool ball valve wires.

Result 1 - The spring-loaded pins can rebound, and the wires are well connected.
Escalate to PSE.
Result 2 - The spring-loaded pins cannot rebound.
Start STEP 2.

Result 3 - The wires are not well connected to the pins.
Start STEP 3.

STEP 2 - Replace the spring, and verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue close.
Root cause: Spring on the pin malfunction.
Result 2 - Cannot be detected.
Restart STEP 1.

STEP 3 - Reconnect the wires, and verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue close.
Root cause: Cleaning tool ball valve wires disconnected.
Result 2 - Cannot be detected.
Restart STEP 1.
