Agilent Infinity 1260 autosampler: Valve to Bypass Failed EE 4014

Hello, I've been using an infinity 1260 autosampler and sporadically during injection I get the error: "Sampler G1329B:DEAAC21082 - Valve to bypass failed [EE 4014, 0]. This causes the system to disconnect and terminate the run. I can restart the entire system, but then it occurs after approximately 4 autoinjections. Does anybody have any idea what is going on or has had something similar happen?
