1-2 - R4.5 Unable to Blend

Modified on Tue, 3 Jun at 11:34 PM

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

1. Blender Interlock Triggering

1-2-1-1 - Find a thin tool (e.g., a flathead screwdriver), press on the interlock, and observe its rebound speed.

Result 1 - Rebound speed is slow.
Start 1-2-1-2.

Result 2 - Rebound within 1 sec.
Start 1-2-2-1.

1-2-1-2 - Wipe the interlock and the surrounding syrup, and pour a small amount of hot water (about 10ml) onto the interlock to flush the internal syrup. Then, verify if the blender can blend typically.

Result 1 - Can blend.
Issue close.
Root cause: Blender interlock sticks

Result 2 - Cannot blend.
Restart from 1-2-1-1.

2. Blender Cup

1-2-2-1 - Check if the fins on the base of the blender cup are damaged.

Result 1 - Some/All of the fins are damaged.
Start 1-2-2-2.

Result 2 - Undamaged.
Start 1-2-2-3.

1-2-2-2 - Use undamaged fins (or replace the base if all fins are damaged) for testing the blending.

Result 1 - Can blend.
Replace the blender cup base, and issue close.
Root cause: Blender cup fin broken.

Result 2 - Cannot blend.
Start 1-2-2-3.

1-2-2-3 - Disassemble the blender cup and observe if the components are assembled correctly. Then, reassemble it correctly and verify if the blender can blend typically.

Result 1 - Can blend.
Issue close.
Root cause: Blender cup reassembly incorrect.

Result 2 - Cannot blend.
Start checking 1-2-3-1.

3. Blender

1-2-3-1 - Verify that all the wires of the blender (power cord, "INTLK(Blender)”, "BTN(Blender)") are securely connected to the connectors in the water system compartment.

Result 1 - Not securely connected.
Start 1-2-3-2.

Result 2 - Securely connected.
Start 1-2-3-3.

1-2-3-2 - Reconnect the wires. Then, verify if the blender can blend typically.

Result 1 - Can blend.
Issue close.
Root cause: Wire disconnected.

Result 2 - Cannot blend.
Start 1-2-3-3.

1-2-3-3 - Check the seven wire connections on the control board:

“110V AC out”

“b15_ BTN1(Blender)”

“b15_ BTN2(Blender)”

“b15_ BTN3(Blender)”

“b15_ BTN4(Blender)”

“b15_INTLK out”

“b15_INTLK in”

And measure the voltage at the 110V AC out on the control board. The expected reading should be 110V

If you see the wires are directly connected without connecting with the control board (see picture below), start Step 6 directly.

Result 1 - Wires are connected, and the measured value is 110V.
Start 1-2-3-6.
Result 2 - Wire(s) is not connected.
Start 1-2-3-4.
Result 3 - The measured value is not 110V
Start 1-2-3-5.

1-2-3-4 - Reconnect the wires. Then, verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue close.
Root cause: Wire disconnected on the control board.
Result 2 - Cannot be detected.
Start 1-2-3-6.

1-2-3-5 - Replace the control board (see SOP here) and make sure the 110V AC out is with 110V. 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 1-2-3-6.

1-2-3-6 - Replace the blender (see SOP here). Then, verify the cleaning tool detection when starting the cleaning process.

Result 1 - Can be detected.
Issue close.
Root cause: The blender interlock fails.
Result 2 - Cannot be detected.
Escalate to FAE.
