PROGRAMMING
Error codes are
displayed here
In an effort to prevent damage to machines and to help operators troubleshoot issues, Synesso™has
engineered several safeguards into the programming. These codes will help users identify operational
issues with the machine as well as automatically prevent greater problems from occurring. By
understanding these codes, operators can remedy issues more quickly.
Error code key (See Pages 38-44 for more info)
BR
– Brew System Codes
BV – Brew Valve has been on for 5 minutes. Valve will be disabled until group is turned off.
OT – Over Temperature. (220F)
UT – Group reads under 180F for 1 minute while trying to heat (Under Temp.)
PR – Pump Relay coil has been on for 5 minutes. Relay will be disabled until group is turned
off.
BP – Bypass Valve has been held on for 5 minutes.
Valve will be disabled until group is turned off.
01, 02, or 03 – Indicate which brew group is reporting an error.
ST – Steam System Codes
LW – Low Water probe is not in contact with water (an audible alarm will also sound)
FP – Fill Probe is not in contact with water for 1 minute.
FV – Fill Valve has been held on for 5 minutes.
Valve will be disabled until machine is turned off.
OT – Over Temperature (270F)
01 – All Steam System Codes end in 01
VM – Volumetric System Codes
UF – Unexpected flow while group is off.
01, 02, or 03 – Indicate which flow meter is reporting an error.
Example:
After brewing a shot, group 2 was left in the brew position. After 5 minutes, the machine will register
a BRBV02 and a BRPR02 error; which translate to “Brew System, Brew Valve Group 2” and “Brew
System, Pump Relay is timed out, Group 2.” At this time the machine will automatically shut off both
the brew valve and the pump relay to ensure they will 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.
