Display shows: BUCKET PWR FLT<br />
One or more of the bucket solenoids was energized during STANDBY. Most likely, an<br />
incorrect change load is in one of the buckets.<br />
Press the FUNCTION button on the CCC. Does the message reappear?<br />
NO<br />
Check the R/B, Y/BR, BL/W, and V/O wires<br />
from the CCC to the bucket solenoids for<br />
an intermittent short to Ground.<br />
NO<br />
Check resistor R813 on the power supply<br />
circuit board for open connections.<br />
IF OK<br />
Check C816 on the power supply board for<br />
excessive leakage.<br />
IF OK<br />
Replace the CCC. See CAUTION.<br />
YES<br />
Unplug P2 from the CCC and press the<br />
FUNCTION button. Does the message<br />
reappear?<br />
YES<br />
Unplug P4 from the CCC and<br />
press the FUNCTION button.<br />
Does the code reappear?<br />
NO<br />
NO<br />
Replace the CCC.<br />
See CAUTION.<br />
Turn the power OFF. Check the R/B, Y/BR, and BL/W wires<br />
at J2 and the V/O wire at J204-3 for a short to Ground. Does<br />
a short exist?<br />
NO<br />
YES<br />
YES<br />
Replace the CCC.<br />
See CAUTION.<br />
Unplug P402 from the dispenser.<br />
Does the short disappear?<br />
NO<br />

YES<br />
Replace the dispenser.<br />
NO<br />
Short in the main<br />
machine harness.<br />
YES<br />
Replace the power<br />
control center.<br />
CAUTION:<br />
Installing a new CCC without determining the cause of the failure may destroy the new board. Use<br />
an ohmmeter to determine if it is safe to install a new CCC. If you use an ohmmeter, check for shorts<br />
(less than seven ohms) between the V/O wire, Y/BR, and BL/W or Ground.<br />
