Aquahot fuel pressure test fail
Hello I am trying to test my new webasto burner fuel pressure. I have followed the manual instructions and it will not activate the fuel solenoid so I can’t get a reading on the gage. I have attempted this twice with no success, I have verified that the pump is pumping, then I tried to do a fuel nozzle test with the same results. My only thought is that the flame sensor is keeping it from opening the fuel solenoid so before I remove the burner again I thought I would ask if anyone else has had this issue. The Aquahot works fine when installed but for some reason it will not allow me to do these two test. Also while this is happening the diesel burner switch is flashing immediately once it is turned on, while doing the test. Again it works fine when installed. We called Aquahot and they haven’t been much help other than to say that we my have to manually activate the solenoid. Any ideas on this and thanks for any help. Tim
