Just be sure to tell them you were referred by MedWrench  

Look at the condenser coil while in heat up, after 212 F the exhaust valve should close. If water continues to leak from the coil, there is debris, rust or a crack in the exhaust valve.  Replace the whole valve, not just the upper portion.  

the 3mm exhaust valve is always suspect here. closely inspect the valve seat on the valve connected to the condenser coil. look for cracks missing piece of material or uneven seat surface. Replace as needed.

Also, these units are notorious for poor connections were the pt100 temp sensor plugs into the Adjunc board. However, you stated you replaced the sensor. That connection causes a lot of high temp errors. 

I see you replaced the Solid State Relay (one under Adjunct 3 board) once in a blue moon those go bad and either the machine doesn't go past 75F or the heaters stay on till infinity.

Is the water pump set to a 40 second fill time?  press Stop button until Code 105 appears on screen Then , press Stop again. Use up/Down arrow keys to adj. fill to 40 secs and hit Stop again.

Note, if you have to remove the exhaust valve and inspect the valve seat with an eye loop if your over 40.

give me a shout and I can send a couple pics of what to look for on these valve seats.

cant seem to post them here.

Thank you everyone that responded to my post and thank you Kevin for a thorough writing. What I just did in between your post was that I ordered three 3mm Solenoid complete valve kits and replaced them all for the system. I took the entire thing apart and clean the copper connectors system and putting in the new ones from the kits. After putting all back and run the machine with unwrapped and the same problem still there: that is it's heating up to 274 degrees and the pressure can only goes to 3 PSI and the HIGH TEMP error appears and the system stops with all the pressure escapes to the reservoir tank.  Can you have any other suggestions for me Kevin and KP?

Thanks and waiting for your response 

Hi Kevin.

I can confirm that the pump was set for 40 seconds. It pumped for 40 seconds then stopped for a fraction of a second and continued for another 20 seconds. I also observed that there was no water escaping to the reservoir tank.

As I posted in the original post, I already replaced the PC BOARD (AJUNC-C3), SOLID STATE RELAY (HEATER), TEMPERATURE SENSOR, three of the systems 3mm SOLENOID VALVE complete kit (solenoid, copper connector, plunger). I set the temperature for 270 and the problem is that when the temperature reaches 275 and the pressure reaches 4PSI it fails with the HIGH TEMP error. 

Thanks in advance for your reply.

Have you checked the calibration on your adjunc? Even though you've replaced it. Bc how are you getting 274 degrees F with almost no pressure? 

bad pressure sensor, serious leak...perhaps water is flowing back into your reservoir?(during heat up do you see bubbles in the rez?)

During heat up, after your temp says 212f, are you still seeing steam blowing into the rez? that would point to the air outlet valve leaking.

Are your fill/ exhaust and air pump valves correctly wired/set up?

As far as water filling, once you've verified that water does flow in with the door closed, start a cycle with the door open, hold the door switch until water start pumping in, then you can let go. Verify it reaches the line, then quickly shut the door before it moves to the heat up phase. 

and finally, during heatup/sterilization are you seeing a ton of steam coming from the rez? maybe your safety valve isn't closing
