Webasto help please😁

[GrandWood]

Installed new webasto evo 40 diesel heater, took 3 tries and then a reset and it fired off on the 4th try. Took a bit to get the fuel pumped up to unit from day tanks in the lazzertte.

Unit works for a bit, couple minutes and then shows flashing error code on the controller( just have the dial type at present) I checked the fuel filter and there’s some air in it. Which maybe the problem, sucking that last bit of air in the fuel line. I’m thinking at some point the air should get out of the lines while restarting unit when it stops.

Also in the pic, I have a tee right near the heat outlet, wondering if I need a bit longer run at the outlet, I’m thinking I may be getting a over temp as the tee is to close to the unit.

Gonna be nice this winter if I can get the unit sorted out, thanks again for all your help

Well took a bit to get the unit going, I was able to get the air out of the line from the tanks to the filter yesturday just by pulling the line off at the output of the fuel filter, didn’t make a mess either. Few more cycles and finally all the air must have got pushed out and unit is working fine now. Nice and toasty this am.

Congratulations. I'm glad you got it working well. When I had a Webasto heater installed in my sailboat, I knew I would find ways to screw it up so I paid someone else to do it. It was fantastic for cool weather cruising.

There's a Youtuber, John McK 47, that has a number of videos that explain the workings of these heaters. It is based on Chinese heaters that are almost an exact copy. So exact that Webasto parts fit. The info is solid.
