    ACW-Red hot fuse

    My Pentair master 400 heater keeps popping the buse fuse on the fireman's switch. Fuse element glows red hot before breaking.

    Any thoughts?
    I have a 35,000 gal in ground salt water pool. My equipment is below pool level. My heater is a Pentair master 400.h

    Welcome to the forum!

    I made a slight addition to your thread title to get it noticed. I wish I could offer a suggestion, but sorry I don't know...
