I have a Japanese heater that comes with Japanese only manual. Can comeone translate this page and let me know what are the possible reasons I'm getting error code 01? I have attached the manual page here.
The resolution of your uploaded image is not that great. It is blurry and hard to read.
However, it appears to say that the 01 error is caused by continuous operation in excess of 8 hours. The 'resolution' section is a little too blurry for me to read accurately, but I think it says something like restart and relight. I am not certain though.
Have you tried shutting it off for a while and then restarting it?
