Jeff, it would be recommended that the pressure hose is inspected for any partial blocks that may be causing the pressure to not reduce in the hose properly. If there is not a partial block, the pressure sensor DC97-03716C can be tested for voltage during operation from the main control MFS-WF318A-T0 (main control has been discontinued by the manufacturer and is no longer available). At the connection CN3, the black probe of a meter would go to the orange wire at pin 6 and the red probe would go to the purple wire at pin 7. There should be a 2.5VDC reading if the main control is sending voltage properly. From there, the red probe would get moved to the pink wire at pin 8 and there should be a 2.5VDC reading here if the sensor is sending a signal back properly. If the voltages are reading properly, the failure would be in the main control.
