Hello, Just looking for some assistant sorting this fault code on a 2007 Sumitomo SH210-5 7241 – Pump main proportional flow valve signal fault. Would anyone have a service manual for this machine or know what to check first. I dont even know where this solenoid valve is located on the pump so haven't tried any diagnostics. I have cleared the fault code and it comes right back when you run the machine again. The machine is still running very strong. Nothing noticeably wrong when operating and certainly not sluggish or slow. Thanks in advance for any guidance. Cheers
