Rework Station 8505D error code 5-E (or S-E?)

hello,

when trying to use my rework station for the first time i noticed it seemed to be generating heat but not nearly to the desired temperature; after a minute or so of tinkering with the AIR control the heat dropped out entirely and the code S-E (or 5-E) appeared on the screen and i haven’t been able to get it to work since.

the item was packed fairly well and i was not able to identify any manner of physical damage. i did remember to remove the bottom screws for the pump per the instructions prior to first power up.

is this something we can fix/troubleshoot or does it need to be replaced?

thanks
