    Waste tank is not shutting off when full. What could cause this?

    Could be a faulty or dirty float switch.
    Also check the fuse.

    Is it in a TM?

    Carpet fiber can keep the float from lifting enough to activate.

    Same as above..... Leave your tank top off and while the machine is running and lift the float switch. If it turns the machine off then its not a problem with the float but more than likely you are getting to much foam and need to use some defoamer.

    If it does not shut off:
    Pull the lead wire off from the waste tank to see if it cuts off the machine. If it does then it will be a problem in your float more than likely. Buy a new one.
