AutoTerm “Check Fuel” error

[RobJH]

Hope someone may know the answer to this.

I've had to disconnect the fuel feed on an autoterm diesel heater. Im now getting fault 78, check diesel system.

Any ideas how to purge the system or get diesel flowing back?

I've read about a Facebook group for autoterm but can't locate it.

Scrap that, sorted it.

The only issue I have now is the vent in the passenger footwear blows cold yet the rear vent is warm.

I've no idea if it's always been like that though.

The vent in the passenger footwell should be pulling in cold air to be heated in the autoterm and then come out of the rear vent so it recirculates the air and hopefully warms it quicker otherwise I’m not sure why you’d have a vent in the footwell

Check that the duct is connected to the rear of the vent as the only way that it can blow air is if it is disconnected. Unless you are confusing suck with blow due to the air movement.

I'll check again on Monday with a bit of tissue to see if it is sucking rather than blowing.

If it is, then I'll giveyself a good slap!!

I've got the same error code. How did you sort it?

I would do as the display says, it couldn't be plainer.
Possibly no fuel or a blockage.

Or, if the installer has connected the fuel supply to the return to the tank you have drained the engine fuel line. ( after long running without engine running )
