    autopilot digital Model # 75003

    autopilot digital Model # 75003 (220V) set in "1 speed pump" is not working. No power on #4, #6 terminals during the programed hours. The load out is connected to a Lorentz AC Power Pac. I've been running all the tests and checked all the fuses. The #1 #2 terminals indicate 220v.
    This device as been working successfully since the last 6 months with no speed pump attached and is now indicating a "low flow" problem.

    Hi pierre,
    Have you check the unit's automatic-flow bypass manifold assembly? The most common problem for "low flow" is a dirty strainer screen. When this gets clogged, the tri-sensor does not receive the proper flow needed to function properly. Good luck!

    Thanks for the answer kentserph, will check that but now my major pb is this:

    A check flow message is caused by too little flow past the trisensor. This is most commonly caused by a dirty filter screen in the manifold, exactly as kentserph suggested. It can also happen if your pool filter need cleaning, or there is a blockage in one of your skimmers or the pump strainer basket.

    Pierre, if you press BOOST, can you hear the relay making a "CLICK" noise? Are you getting any voltage (AC)across #4 and Ground, #5 and Ground, and #6 and Ground?
