La Marzocco Auto-Fill Fix
Hello all. At the shop in which I work, our LM Linea is not auto-filling. It is still operational if we manually fill the tank, so we know it is not the pump. I have a hunch that we have a problem with the Auto-Fill valve, possibly a build-up of scale or some like blockage. Any other ideas?

Yes. That would be a CPU issue. But it would pay to investigate Kevin's idea to rule out any other kind of signal wackiness that might be confusing the cpu. You might try taking the top off the CPU box and disconnecting/reconnecting all the wire bundles to make sure all the connections are good. And the fan needs to be working.

I would agree- after going through the diagnostic tests to date everything points to a faulty cpu- however as a last step you could also double check the ground/earth connection. If this connection is not fixed then the autorefil also will not wwork. It is unlikely this is the problem though, as obviously the machine has run for some time with AWR functioning correctly
