Error log key
Logs are in format: AABB##
AA = system code
BB = subsystem code
## = group or section effected
BR – Brew system
BV – Brew Valve open timeout (valve has been held open for 5 minutes)
01 through 04 – groups 1-4
OT – Over temp (over 220F (104.4C))
UT – Under temp (under 180F (82.2C) for 1 min while group is trying to heat)
PR – Pump relay on timeout (relay has been held open for 5 minutes)
BP – Bypass valve open timeout (valve has been held open for 5 minutes)
ST – Steam system
LW – Low water probe is dry (an audible alarm will also sound)
FP – Fill probe is dry for 1 min (an audible alarm will also sound)
FV – Fill valve open timeout (valve has been held open for 5 minutes)
OT – Over temp (over 270F (132.2C))
VM – Volumetric system
UF – Unexpected flow while group is off (leaking or filling)
Example:
After backflushing, group 2 was not returned to the off position. After 5 minutes, the machine registered a
BRBV02 and a BRPR02 error. At that time the machine shut off both the brew valve and the pump relay to
ensure they would not be damaged. They will remain off until the group is returned to the off (far right) position,
which allows the group to return to normal operation.
