My 2hp 50ltr tank build to 1bar and stops......

Hi, i've got a 2 hp 50ltr compressor which seems to stop around the 1 bar pressure. the motor seems to run fine and goes on and on but no matter how long i leae it on for it doesn't get past 1bar on either the main tank gauge or the adjustable working pressure..... i've hardly ever used this tank ad it worked well when i first got it...any suggestions??
cheers

Hello John. I've pretty much covered the diagnostic steps for why a compressor won't build pressure right here.

If that page can't help you figure out what your compressor problem is, maybe it's time to visit the repair shop with it?

Good luck, and thanks for the photo.
