What to do if the LED screen of my Hanchen GFK-160A won't light up?
First, ensure the power cord is properly connected. If it is and the screen still doesn't light up, the power connection might be broken and needs replacement.
Why Hanchen GFK-160A Laboratory Equipment cannot pump water but I can hear the pump?
The pump might not be broken, but unable to pump water because it is dry inside. Try filling the machine with water several times. If the problem persists, remove the mesh filter and manually add water into the tube using a cartridge. Start the machine to check if it works; if not, repeat the second step.
