Robinair 34700 recovery problem

My ser number is 22447. Date Code 0298. In recovery mode the machine will only run for several seconds, and then it shuts off for high pressure. I have verified that the recovery solenoid is opening. The compressor is running. The machine high and low guages show that the vehicle has 75psi. We connected an auxillary guage to the port just before the filter drier and it shows shows 35 psi when the machine is trying to recover.

    Today, I ran the machine in recycle for approx. 30 minutes. The machine ran as expected. Following the recycle, I ran it in recover without hooking it to a vehicle. It Pulled the lines down into a vacuum after a minute and shut off showing complete at the end of cycle. That was perfect. I hooked to a vehicle. It recovered perfectly. I have no idea what I did. I may have had some blockage that the recycle or vacuum pull cleared. Not sure. But, it works.

    Yes,you are right! There was blockage somewhere in the manifold assy.that the recycle or vacuum pull cleared! You can continue to use the machine. but remeber every time when you press recover, do not skip "Clearing in pogress" mode. because during self clearing machine test it self to work normal.

Machine won't recover, it gets stuck on "clearing in progress" Also won't vacuum, it says that "pressure exist press any key to continue" Your help would be greatly appreciated

I had a similar problem with a Robinair 17800b. The machine got stuck in Clr or (Clearing) while changing from R-12 to R-134a. If the tank (R-12 or R134a) does not have at least 10 pounds of refrigerant in the tank before you change to another refrigerant, the machine will stay in the clearing process. I called tech support and they walked me through a process that resets the machine. The reset involves entering a code while in r-12 mode, then removing all hoses and switching the switch to R-134a mode and entering another code. The call to the tech line took about 5 mins. The number I called 1-800-822-5561.

LX30H THROWS A CODE EO after running awhile. I hit the high reset button under the flaps on the front for both the boost and reg elements . It will work for a couple cycles and then does the same thing....

Machine won't fill or won't fill high enough. site water pressure meets minimum flow pressures. (LX18, LX30 display shows working.
"E0," "E2," "E3," or "E4". LX40 display shows "DR1 PRBLM," "FILL1 PRBLM," FILL2 PRBLM," or "FILL3 PRBLM". Machine will not run.)

1. Low water pressure - check for clogged hose strainer; check that

2. Make sure probes are clean

3. No water pressure - main water supply valves may not be

4. Drain valve open - turn machine OFF to drain machine, then
ON. Repeat twice (this assists in clearing any drain valve
obstructions). Wait for machine to reach READY mode and
press WASH. Slowly open door several seconds later and note
water level. Close door; 30 seconds later, open door slowly and
check that water level is the same as it was. If not, repeat the
OFF-ON procedure. If problem persists, call your local Hobart
Service Office.

5. Delime machine.
