    FMM making clicking sound

    I finally got my ATK and FMM working properly and everything has been working great for the last week or so. I wake up this morning and the FMM itself is making a clicking noise. The click happens ever 4-5 sec and the PMUP is not engaging (in auto or ON setting). I tried doing a reset on the FMM itself and it is having the same issue.

    Any ideas?

    The click itself sounds mechanical. Similar to clicking sound the APEX makes when switching power on or off.

    From your description, sounds like it's a relay cycling. Does the clicking stop if you disconnect the pmup from the ACC port? If so the pmup may have failed with an electrical short.

    If the clicking continues after you disconnect the pmup, and you are using the FMM with the power supply attached, does the clicking stop if the power supply is disconnected? This would suggest an electrical problem in either the FMM itself or the power supply. You can get along without the FMM power supply by plugging the pmup (if it's working properly) into the EB832 instead.

    The clicking stops when the PMUP is disconnected. That's a bummer, was hoping it would be an easy fix. I guess I'll contact the seller and neptune to check on the warranty. Ive had this set up for less than a month.

    It did get resolved, The PMUP was burnt out. I was able to contact Neptune and they replaced it under warranty and it is working fine!

    I have the same issue. Clicking from FMM. Pump impeller jumps but won’t turn. It occurs in Auto and ON. How long is the warranty on the pump? Do I just send in the pump? Thanks.
