together until it resets.
C.
Press the “Less Thick” & “More Thick” buttons together to manually initiate a Sanitize Cycle when ready.
2.
Dump a large cup of water inside the chamber to verify it drains.
A.
If it drains, proceed to Step 3.
B.
If it doesn’t drain, ensure the drain is not pinched, kinked or clogged and proceed to Step 3.
3.
Check if water is continuously spraying in blending chamber.
A.
If water is spraying with the door open (not just residual water drops) and the blender is powered ON, turn the blender
OFF:
a.
If the water continues to run, replace
b.
If the continuous water stops and starts back up as soon as you boot the blender back on, replace
Low Voltage
Control Board (LVCB)
(Parts Manual: Control Boards, Lower).
c.
If water is not continuously spraying, proceed to Step 4.
4.
Make sure the Water Shot Orifice (WSO) is clear with the Water Shot Tool, paperclip, small gauge wire, etc.
A.
Blenders with , use your Water Shot Tool that is provided on the back door of the blender.
Make sure and note
how far in the WSO you can get.
The WSO travels up 3/4" and then takes a turn to the back and to the left.
Ideally, you
should be able to get the Water Shot Tool close to 2" in the WSO.
5.
Hold “Less Thick” & “More Thick” buttons together for 8 seconds to initiate a sanitize.
6.
Bring up the LVCBS Status Screen (Press the “Left Arrow” & “OK” buttons for 7 seconds until the Status Screen appears on the
screen).
Locate Line E: "ChmTemp: XXX" and Line F: "StmTemp: XXX"
A.
Wait 10 minutes before proceeding to the next step.
B.
If the StmTemp never rises above 80°, proceed to Step 7.
C.
If the StmTemp rises above 218°, proceed to Step 8.
D.
If the StmTemp rises to between 209
-
218° and ChmTemp never rises above 184°, proceed to Step 9.
E.
If the StmTemp rises to 200
-
218° and then drops 30° or more suddenly, proceed to Step 10.
7.
Verify the BF Steamer Heater is heating properly.
A.
Verify wiring at the steamer tank is intact and correct.
B.
Check for continuity through steamer elements with a Multi
-
Meter.
a.
If resistance is present, proceed to Step 7.C
b.
If no resistance is present, replace
(Parts Manual: Heaters & Position Motor).
C.
Verify steamer tank is receiving 120 VAC by measuring the VAC at the steamer elements on top of the BF Heater. If no
voltage is present, measure the VAC between the bottom post on the Thermal Cutout (orange wire) and the Main post
(white wire) on top of the heater.
If there is still no voltage present, remove the right side panels and proceed to Step 7.D.
D.
The voltage for the steamer tank is located at TB3 on the High Voltage Control Board (HVCB). TB3 is located at the top
center. Measure the orange wire and the white wire across from it in the connector. If no voltage is present at this point,
replace
HVCB
(Parts Manual: Control Boards, Upper).
8.
Remove left side panel. Perform a Deep Clean and Purge Process.
For full instructions, send an email to [email protected] to
request the “Deep Clean & Purge Process” Article.
9.
Verify, again, that there is no clog in the chamber.
If there is no clog, check the Chamber Thermistor wiring. Verify that both
sides of the connection are secure.
Verify
the connection is secure on the LVCB, located in the upper left corner and labeled as
TB18.
10.
Locate the two wires connected on the side of the BF Steamer Heater, this is the Thermal Cutout.
Remove the orange jumper
wire connection from the top of the Heater.
Then, remove the Orange wire from the bottom of the Thermal Cutout and
connect it to the open power terminal.
Reset and restart the sanitize cycle.
If this problem no longer exists, the Thermal
Cutout has failed.
Replace the
(Parts Manual: Heaters & Position Motor).
Error 77:

TRIGGER: Tempco Heater above 310°, BF Steamer Heater above 250° or both below 40°
1.
Reset the blender by pressing “Regular” & “More Thick” buttons together for 7 seconds to soft
-
reset the blender.
2.
Ensure water supply is on and regulated to 25
-
65 PSI.
3.
Bring up the LVCBS Status Screen (Press the “Left Arrow” & “OK” buttons for 7 seconds until the Status Screen appears on the
screen) and locate Line F: "StmTemp: XXX"
A.
If the “StmTemp” is above or below the
