The washer is set on cold/cold. The hot water faucet is turned off. The washer should not be asking for hot water because it is set to cold/cold. It asks for and received cold water. At some point early in the wash cycle, it starts asking for hot water. The nf alarm sounds because the hot water faucet is turned off. Once the start/pause button is pushed again, it either asks for hot water again and the alarm sounds again or it asks for and receives cold water. I have had the washer for less than a week. It is new.

Hi, when you use the hot water selector switch, it should only supply hot water. The hot water will fill more slower then cold, but you should not be getting any cold water what so ever. You say it is a new washer. You can try this. Try and slide the machine out enough to get to the supply hoses to where they connect to the washer inlet fittings. Unplug the washer. The hot water at the faucet should always be the left one. On the washer, they will be marked with a C and a H, cold, hot. Use a flash light to make sure they are in the right place. If they are, turn off both faucets. Now, remove the hot water hose where it is connected to washer. Hold it in the tub, and turn the water to this hose only on. See if the water gets really hot like it should. If not, shut off water, and do the same using the other hose. The reason is, sometimes the hoses may be switched, or the plumbing may be backward. See if the right faucet is putting out cold. If all seems to be correct, you have a problem with the water fill solenoid. If the machine is still under warranty, call your repair man. This is something you cannot take on your self. Checking the hoses like I asked may be your problem, but if not you will need to have it looked at or live with the way it is to save you $$$$. I wish you the best on this. You may need to use a pair of pliers to loosen the hoses also.

try to do cold cycle first without doing warm cycle first

Might be a bad inlet valve. To confirm, swap the hot and cold hoses to your washer so that the cold water feeds the hot water connection and the hot water feeds the cold water connection. Turn off both hot and cold water faucets. Set the washer for a warm water wash. Turn on the cold water faucet, and check the flow. Then turn off the cold water faucet, and turn on the hot water faucet and check the flow. If the cold water flow fill slowly, then the problem is with the inlet valve.

It an easy part to obtain from an appliance supply house. To install disconnect the hoses to the back of the machine, and remove the back panel to get access to the valve. Should only take a couple of minutes to remove and install. Hope this helps you.

Are both the hot and cold water faucets turned on?
Turn on the water. Check the household faucets to see if the hot and cold water faucets are turned on. Completely open both faucets for proper fill.

NOTE: Both hot and cold water must be connected to the washer and turned on; the washer will not properly operate with only one incoming source of water.

Turn off the water and remove inlet hoses from the inlet valves in the back of the washer. Inside the inlet valves are screens. Remove any accumulated film or particles from the screens. Reinstall hoses, turn on water, and check for leaks.

If the water pressure is too low, the washer may not properly operate. To find out your exact pounds-per-square-inch (psi) value, contact your local water utility company.

Use only HE High Efficiency detergent. Using non-HE detergent, or more than the manufacturer's recommended amount of detergent, can cause excessive suds. The excess suds can prevent the washer from detecting the incoming water.
Concentrated detergents labeled 2x and higher will require a small amount of detergent based on load size. Always follow the manufacturer's recommendations.

At the back of the washer where the fill hoses from your faucet attach to the washer there should be a marking of an H for hot and C for cold. Test your washer by selecting a hot setting. If water comes out cold on hot setting or hot on cold setting, then just reverse the hoses at faucet.

I believe the code HF is telling you that you are not getting hot water. Check faucet in back and make sure water is turned on at both hot and cold valves. Even if you only use a cold setting, the hot water needs to be turned on. Also check washer fill valve screen. Turn off water and take off hoses at washer. Inside valve are sceens that may be clogged.

Is the little screen in your hot water line clogged? (not the hose - inside the connection on the washer where you attach the hot water) Please check it.

it will maintain 60 degrees but cycling hot cold

Have you tried checking your cold water supply faucet? Are you sure there is cold water running out of that faucet before you hooked up the hose? Is it possible there is a shut off on the supply valve that isn't turned on? Therefore it will not run on cold water setting? This actually happened to me once. We went away for a week and turned the water off for the hot and cold supplys. Came back to do laundry and only turned the hot one on and not the cold. Good luck!
