There’s no way I’m buying an $800 kit to calibrate my old machine. That price kills me. Wish I could rent it. I’ve got my 2540ea apart on my center island in my,kitchen as I type this. Took apart all 4 solenoids and ultrasonic cleaned the plungers, hoping for the best. I’ve got a high temp fault. The machine doesn’t get to 30psi of pressure. Gets up to about 24 or 25 psi when it hits 273 degrees and then faults at either 274 or 275 or a few minutes with no more pressure increase. I was hoping it was the air jet. I replaced it, and the rpi part I got was spitting water worse than my original. So I’m waiting for a second one. I’m afraid it’s the temperature sensor, but the service manual didn’t include any ohm readings to test the sensor. Any ideas? I’ve fixed just about every part on this 20 plus year old machine and hate to trash it. It’s got the Adjunct 3 board. Thanks for making this video. Not too many out there. 😊
1st step would be to determine if the readings are accurate bc that temp and pressure are not inline with each other. If the temp is accurate then you either have a pressure leak or need a calibration. That's where I would go 1st. Verify and calibrate
@ thanks very much for getting back to me. I was thinking the air jet was leaking, not allowing it to build pressure. My problem is that I don’t have the tools to properly test the pressure and temperature. (And that means I can’t properly diagnose the machine). if the air jet isn’t the issue I will have to trash the machine. It gets to the point of not being worth the cost of repair. What a shame. Thanks again.
@Samlol23_drrich the air jet is supposed to leak. It's how the steam circulates in the chamber. But the safety release valve shouldnt...if you overfill the rez so the safety release is half covered, you'll be able to see if it's leaking, same for the air outlet valve. There's probably a biomed company near you with a test kit than can trouble shoot it for you
@ truly appreciate all of your expertise. The reason plumbers and electricians are required to do apprenticeships is for exactly what I learned from your reply. Would have never thought to test the safety release for leaks by overfilling the reservoir. (Maybe that’s what my staff is doing every friggin time they fill it). Something I did fixed it. Even though I bought a new air jet, after I installed it the machine had the same symptoms, and the new jet was leaking much more than I thought it should. I know the machine like the back of my hand. How much steam comes out of that jet and the new one just didn’t look right. I ordered a second new one but figured I would replace the entire relief valve assembly, so I bought the entire thing. As I said in the prior post, while waiting for the 2nd day delivery, I brought the machine home and took it apart just in case there was a leak from one of the solenoids. I took all four apart, cleaned the copper seats and ran a carb cleaner brush through all the orafices, then pulled the temp sensor and cleaned it (gently), pulled every wiring harness and sprayed contact cleaner on both ends then put it all back together this morning with the new part that was delivered late yesterday. Just ran a cycle and it worked perfectly. So something I did fixed it. Once again, thanks for getting back to me and sharing your expertise. It’s something most won’t do (see my video on the lack of support from Hayward when my pool heater had an issue. Once they found out I was a consumer they wouldn’t help me). Thanks again! Rich in NY

What component is bad on the board to cause it to jump around.
It was suggested there may be a cold solder joint on either the pots, or the larger connector on the back. I have yet to look into that.
@@The_Biomed thanks I do a lot of board repair so I was curious thanks.
@johnm4962 if you come across an adjunc 3 pcb with a similar issue, let me know about the cold solder joint scenario
@@The_Biomed yeah I don’t come across these boards often and my machine doesn’t have this fault.
You could send me a bad board and I could go over it ?
