Synesso Espresso Machine

Technical Manual 46
PROGRAMMING
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
Error codes are in this format: AABB##
AA = system code
BB = subsystem code
## = group or section experiencing the issue
BR – Brew System Codes
BV – Brew Valve open time-out (valve has been held open for 5 minutes)
01 through 04 – groups 1-4
OT – Over-temperature (over 220F)
UT – Under-temperature (under 180F for 1 minute while group is trying to heat)
PR – Pump relay is on and timed out (relay coil has been on for 5 minutes)
BP – Bypass valve open time-out (valve has been held open for 5 minutes)
ST – Steam system Codes
LW – Low water probe is dry, meaning it is not in contact with water (an audible alarm will also sound)
FP – Fill probe is dry (water is not touching it) for 1 min (an audible alarm will also sound)
FV – Fill valve open time-out (valve has been held open for 5 minutes)
OT – Over temperature (over 270F)
VM – Volumetric system
UF – Unexpected ow while group is off (leaking or lling)
Example:
After manual back ush, group 2 was not returned to the Off 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” errors. 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.
