4. Open front door and inspect both front and rear Rotary Nozzles for damage. Replace either Rotary Nozzle (Parts Manual:
Inside the Chamber) if damaged.
5. If water is connuously spraying from either Rotary Nozzle, replace Manifold (Parts Manual: Water System).
6. Remove le side panel and inspect for a water leak and replace parts, as needed.
Error 8E: Chamber Thermistor Out of Range
TRIGGER: If the Chamber Temperature and the Heater Temperature have a dierence of 50° before a sanize cycle
1. Reset the blender by pressing “Regular” & “More Thick” buons together for 7 seconds to so-reset the blender.
2. Ensure blender has the latest Firmware Version.
A. Press the “Le Arrow” & “OK” buons for 7 seconds unl the Status Screen appears on the screen. Locate
“FWXXXX” in the top right corner. FW Version should be FW0334.
3. Bring up the LVCBS Status Screen (Press the “Le Arrow” & “OK” buons for 7 seconds unl the Status Screen appears on
the screen) and locate Line E: “ChmTemp: XXX”
A. Verify "ChmTemp" matches air temperature in chamber.
B. Check the Chamber Thermistor Wiring and Wiring Harness to ensure wiring is connected securely and there is no
water damage on or around the Thermistor.
C. If wires or the Chamber Thermistor are damaged, replace Chamber Thermistor (Parts Manual: Glossary).
D. If temperatures are 100°F or more (more likely closer to 200-400°F), replace Chamber Thermistor (Parts Manual:
Glossary).
Error 8F: Sanize too Short
TRIGGER: Sanize cycle takes less than 7 minutes for 2 consecuve mes within 24 hours
1. DO NOT Reboot the blender.
2. Bring up the LVCBS Status Screen (Press the “Le Arrow” & “OK” buons for 7 seconds unl the Status Screen appears on
the screen) and locate Line E: “ChmTemp: XXX”
A. Verify the “ChmTemp” is in between 67 and 100°F and that the air temperature inside the chamber matches the
“ChmTemp.”
a. If the temperatures are the same, ensure blender has the latest Firmware Version. Press the “Le Arrow” &
“OK” buons for 7 seconds unl the Status Screen appears on the screen. Locate “FWXXXX” in the top right
corner. FW Version should be FW0334.
b. If the temperatures are dierent, proceed to Step 3.
B. If the temperature reads above 100°F, proceed to Step 3.
3. Check Chamber Thermistor wiring and wiring harness to ensure it’s connected securely and there’s no water damage. If
they are, replace Chamber Thermistor (Parts Manual: Glossary).
Error 90: DC Power BUS Brown-Out
TRIGGER: Incoming voltage is equal or less than 75VDC BUS Voltage (Approx. 55-60VAC)
1. Error will auto clear once the voltage is within range. Verify the blender is on a dedicated 15A, 120V circuit. If it is not,
install the blender on its own circuit.
2. Ensure the blender is not on any extension cords or power strips. It must be plugged directly into the wall outlet.
3. Locate the High Voltage Control Board (HVCB) and verify all connecons are secure.
4. Unplug the blender for 2-3 minutes. It is not necessary to have the blender unplugged for any longer than that me peri-
od. Plug back in and power back on. If the Error 90 returns, replace HVCB (Parts Manual: Control Boards, Upper).
Error 91: Mix Motor FET Destroyed
TRIGGER: Current being detected in the Mix Motor circuit while it is inacve or 0.4A for 2 seconds
1. Locate the High Voltage Control Board (HVCB) and verify all connecons are secure.
2. Turn the blender o, wait 30 seconds and turn it back on.
3. If the error returns, replace HVCB (Parts Manual: Control Boards, Upper).
Error 92: Pump Motor FET Destroyed
TRIGGER: Current being detected in the Mix Motor circuit while it is inacve or 0.4A for 2 seconds
1. Locate the High Voltage Control Board (HVCB) and verify all connecons are secure.
2. Turn the blender o, wait 30 seconds and turn it back on.
3. If the error returns, replace HVCB (Parts Manual: Control Boards, Upper).
