 ===Troubleshooting===<!--Historical significance of a failure is better suited for Wikipedia or other sites.  You are encouraged to link out to these sites from this section.  --> <!--Problems are user oriented since a problem to one entity may not be a problem to another, Symptoms are an observable, and sometimes measurable trait, Fundamental causes connect the problem with subsystems or symptoms, and Solutions are actions that can be taken to remedy the problem -->

 |Primary Control Unit not starting up fully
 |Partial or fully dead screen.  Failure to fully boot up the PCU.
 |Weak connection at the power supply due to corrosion and possibly overheating if ran for long periods.
 |Check all connections in the PCU, especially to and from the power supply, for blackened/burnt wires or corrosion.  Grind away anything that may impede a good connection.
 |-
 |Quick draining of connected gas tanks
 |Gas tanks drain much faster than expected by calculation.  Hissing in the mass flow controller is louder than expected.
 |Leak in Mass flow controller.
 |Open up the mass flow controller and identify the point of leakage.  Spraying with soap is an option but care for electrical connections should be taken.
 |-
 |Improper pH control
 |The pump module is operating but pH is not adeqautely adjusting
 |A clog in the buffer line.  This is common for thin tubing where salting out of any pH adjustment solution could occur.
 |Try and break leak in the tubing, cut leak out of tube and rejoin tubing together, or replace tubing.
 |-
 |Failure to pump
 |Pump heads are rotating but fluid is not moving
 |Pump head may be out of alignment due to a breakage on the inside. This keeps the pump head from being able to exert pressure on the tubing.
 |Open the pump moduel and identify broken pieces. Super glue or replace broken parts.

+===== '''Gas trapping''' =====
-|-
+Filling a tall vessel in part with water, turning a graduate cylinder upside down in the water, and running a tube from the fermenter, up into the inverted graduated cylinder can allow for gas to be trapped and the volume of gas produced measured via the graduations on the cylinder (by measuring gas level before and after).
