4. Measure resistance on the BF Steamer Heater with a Mul-Meter. It should read 3-10K ohms. If out of range, replace
BF Steamer Heater (Parts Manual: Heaters & Posion Motor).
Cauon: The steamer tank may contain hot water.
Error 78: Scour Temperature Outside of Allowable Range
TRIGGER: Scour Heater temperature is above 180° or below 40°
1. Reset the blender by pressing “Regular” & “More Thick” buons together for 7 seconds to so-reset the blender.
2. Ensure water supply is on and regulated to 25 - 65 PSI.
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: "ScrTemp: XXX"
A. If the “ScrTemp” is above or below the Trigger level, replace Scour Heater (Parts Manual: Heaters & Posion Motor).
4. Measure resistance of the Scour Heater Thermistor with a Mul-Meter. It should read 3K-10K ohms. If out of range, replace
Scour Heater (Parts Manual: Heaters & Posion Motor).
Cauon: The scour tank may contain hot water.
Error 79: Rinse Water-Shot Time Too Short
TRIGGER: Rinse water-shot target volume of 100mL is reached before 4 seconds
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. Check for any leaks inside the blender.
4. Inspect the Water Shot Orice (WSO). Ensure the hole is not damaged.
5. Check if water is connuously spraying in blending chamber.
A. If water is spraying with the door open (not residual water drops) and the blender is powered ON, turn the blender OFF:
a. If the water connues to run, replace Manifold (Parts Manual: Water System).
b. If the connuous 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 connuously spraying, proceed to Step 6.
6. Check that the amount of water dispensed is being accurately registered by the Flow Meter.
A. Remove the Water Shot Hose from the blending chamber.
B. Get an empty cup to catch the water.
C. 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 J: “Count XXXXmL”
D. Reset the error by pressing “Regular” & “More Thick” buons together for 7 seconds and catch the water in the cup.
Compare the water in the cup with the mL reading on Line J.
a. If the amount in the cup matches the count on Line J, proceed to Step 7.
b. If the amount in the cup does not match the count on Line J, replace Flow Meter (Parts Manual: Water System).
7. Ensure the Rotary Pump Head (RPH) spins freely with lile resistance.
A. Remove the le, right and rear panels and locate the Water Pump Motor (WPR) down low.
B. Disconnect the metal band securing the Rotary Pump Head (RPH) to the WPR. Manually turn the sha key on the
RPH. Sha should turn smoothly with lile resistance. Replace Rotary Pump Head (Parts Manual: Water System) if hard
to turn or locked up.
8. Ensure the mechanism on the Water Pump Motor spins freely. If not, replace Water Pump Motor (Parts Manual: Water
System).
Error 7D: Lower Scour Minimum Flow Limit
TRIGGER: Lower Scour minimum ow limit of 60mL was not reached within 2.5 seconds
1. Reset the blender by pressing “Regular” & “More Thick” buons together for 7 seconds to so-reset the blender.
2. Ensure water supply is on and regulated to 25 - 65 PSI.
3. Verify Water Pressure Regulator is installed correctly with an arrow poinng in the direcon of the water ow. If damaged,
replace Water Pressure Regulator (Parts Manual: Glossary).
A. SN 19783D and later will have an Internal Water Pressure Regulator.
4. Remove Lower Scour Nozzle, clean nozzle and orice. With nozzle removed, close front door and to so-reset to ush the line.
A. If Error 7F occurs, inspect/clean out the nozzle and scour nozzle orice and to so-reset.
B. If "Blender Needs Water to Blend" appears or no error occurs, re-install the Scour Nozzle and proceed to step 5.
