I would be very careful releasing refrigerant from the liquid side of the tank as suggested earlier. Knowingly releasing R134 into the atmosphere carries very large fines if you get caught and is very environmentally irresponsible.
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.
I think your machine is working normal! Robiaair 34788 is high bred technology machine, you can't forse on it to fast recover! It will compleate the process it self. However if you still think this is not working normal you can check low/high side hose & coupler for any block.
Hope this will be helpfull to you. Good luck
