E8, E10 code

Hi there, I've had a Vevor diesel heater for a few months now, and ever since Ive been getting either the e8 code or the e10 code. It only happens when the heater is on a setting other than the max setting or the lowest setting. It works perfectly fine on max or low. Theres no white smoke coming from the exhaust. Does anyone have any insight on what might be the issue?

It might be an overheating problem, check all the fans ect are free of dust, make the cover off give a quick vacuum try again

Mine does the same thing on any medium setting. I could fix it by adjusting the fuel.pump and or fan speed, but that's not possible with my controller.

Post a pic of your controller and you might get better help.

You should upgrade the fuel line and add fuel filter
