Door gasket intermittently not retracting

This machine is fairly new and has been having this issue off and on. My question is, has anybody had a problem like this where you have good vacuum to retract the gasket back inside the groove but will not pull even a new gasket in place? I even plugged the steam inlet port that pushes the gasket against the door and still won't retract. Also the gasket feels somewhat loose at bottom of the groove. Almost seems to me that groove at the bottom is wider for some reason because I spun the gasket around to make sure is not the gasket and looseness is very consistent at that location. Hopefully someone has an idea. Thanks everyone. Have a great weekend.

Does the control indicate that the door is unsealed after the door unseal process is complete?

 

I would start with changing your check valves in your exhaust manifiold.

I have seen this before on the V-16/20 and the bigger V-60. I would try a new door seal and check CK-8. There isn't much between the channel and the drain. I'm sure S-37 has been checked and you have vacuum from S-7. So there could be a vacuum leak, and being intermittent CK-8 may be it. Good luck.

just had the same issue.

 verified s35 wasnt leaking steam back into the seal, verified s37 was allowing steam out, ck6 and ck8 were in proper working order. S7 was creating a good enough vac to pull the steam out. 

seal was clean, channel was clean. had a 2nd machine to test with, swapped seals and the issued stayed with the seal. "crothall" claims to of replaced seal a year ago, so either their lying, or using inferior products. Either way, it needs a new door seal $$$$$ so happy I wasted my day on a door seal

I had this issue a few months ago, i checked all valves, and seals, and still had the "too long to Retract Seal" error, i ended up finding out that the door seal would soften and stick ever so slightly, i ended up cleaning the seal grove, seal surface on the door and the seal itself, and i havent had a problem since
