Eberspacher heater problem

[bogdan2305]

Hi guys. I have an Airtronic Eberspacher heater. It worked fine until two days ago. The heater start but it gets out only smoke on the evacuation tube. After 5 minutes of running, it appears message: "ERR" and it does not heat the aer. I checked air and gasoline. Everything ok. I googled for the error ERR but with no luck.

Before this, it appeared error 051. I removed the battery source and no more error 051. Instead, it appears error ERR, after 5 minutes of running. What can be the problem? Thanks in advance.

Fault code 051 is a flame fault code , meaning it detected a flame when there shouldn't be one or wasn't one when there should be one
May occur when it not gone through the full shut down process and it then forced to start up too soon .

Check all the hot air outlets and inlets are not restricted and or blocked , check the exhaust isn't restricted , and the induction inlet isn't restricted or blocked .
