The unit will not fill and is flashing up the code LF. LF stands for Long Fill and can be triggered by anything from a water supply problem to pressure switch problems. In this case there was no water coming to the unit … so the fill was extra long! Lol.
EDIT: Other things to check for with a LF code:
1. Did someone tell you that you could use just cold water on your washer? I’ve noticed a lot of people trying to use their washers with only a cold water hookup. The various new ‘cold water’ detergents have not helped either. Your Duet washer will not work properly with only the cold water hooked up. It still measures the temperature of the water entering the machine, and if it is too cold it will still add some hot to bring the water temp up a bit. I think it tries to make it around 68 deg. Here in Canada, our tap water can be down as low as the low 40′s F – so a fair amount of hot water is required to bring the temp up. The next question I hear you asking is … why? I wan’t to use just cold water. Well, actually, no you do not. Do this as an experiment. Take the cold water from your tap and measure the temp. If it is below 50 degrees, add a handful of detergent and see what what happens. It will not dissolve … or if it does it will be sort of thick. Soap’s need a certain degree of warmth to activate and tap cold is often too cold to do that. Your clothes will not be washed properly in this situation.
2. Anti-flood hoses. These hoses were designed to shut off a flow of water if they burst. So … a couple of things about these. They only come in braided stainless steel. I’ve never seen one of those hoses burst. They are wrapped in a sheath of stainless steel metal … they can’t burst. So why the anti-flood valves built in? Answer: so they can charge you more. Next: those hoses are famous for triggering off the anti-flood valve on just a regular washer fill. Often it will be just one hose that it happens on, but that means that when it is calling for water from that hose and not getting it, the LF code will be triggered. This most often shows up on the rinse cycle.
3. If you are getting LF and water is entering the machine … and creeping up the glass on the door, then you have a water pressure switch or pressure hose problem. Check out this post for one of the more common problems I see with the pressure hoses. In this case, water is actually coming in, the machine is just not able to sense it coming in.
4. Kinked fill hose?
5. Taps turned off?
6. Are your feet wet? Is the water coming in but draining out via some major leak on the bottom? lol.
If any of these ideas helped you or if you found it to be something else, please add a comment here for me. I learn as much from others as I do from my own observations!
