    is there a way to bypass this 'high presure reset' ? it does not make sense at all. it comes on in any mode of operation .

HELLO I HAVE A ROBINAIR 34788, MY UNIT WILL NOT CLEAR THE LINES. I TRIED SHUTTING OFF AND ON , BUT LINES ARE STILL HOLDING PRESSURE. I ALSO CANT RECOVER BECAUSE IT WILL NOT GET PAST CLEARING. THANK YOU

sounds like you need to check the grommet between the motor and the pump. If this grommet connector breaks, the motor will come on but the pump will not work. Turn the unit upside down and look where the motor connects to the pump. Be aware if you can lose your oil while turning upside down unless you cap the port and exhaust. If this is it, go straight to the Robinair web site and you can order one for around $25.
