Difficulty with the HED supply "error, MS fault 2  2

Hi,

this error message could happen if there is a really huge amount of air/water in your system. If the error occurs after pump down, you should wait about 1-2 hours to move forward.

Otherwise it could be a problem with the power supply itself or the HED.

Try to clean the HED, if this doesn't help call the Service to test/replace the power supply.

Thanks very much, appreciated. I also suspect the HED power supply. The filament comes on briefly and goes off. Anytime you tried checking for anything, even tried tuning, the filament comes and goes off.
