Salam,
I have an osaka gas heater (2015 model) and I'm getting two errors on it:
1.A blinking error 01. When this happens, the air from the heater becomes cold. If I turn the heater off and then back on, it works fine. I use the heater around 10 hours/day, and usually get this error once very 3 days.
2.Recently I started having another issue. A light on the control panel starts blinking (the one that is made of 9 small squares). It doesn't give an error code when this happens, and the heater continues to work while this is happening. I tried google translate to see what was written next to the icon, but it just shows up as some random numbers.
Anyone have any idea? Thanks!
