Try the following, may work:
Press the Start/Cancel button together until all the console Led's illuminate

1. Press both Start/Cancel and On/Off buttons together until 'd off' appears
2. Default screen should return. Switch off.
3. Wait for 2 minutes to try the door. If helped click.

Check the filters in both ends of the hoses. If they are clogged, it will throw the timer off. If it figures on 2 minutes to fill but it actually takes 6 or 7 minutes, the timer won't be accurate.

I'm not saying you don't have a problem. But just to be clear. You do understand that the last minutes on these machines can vary. The machine senses certain conditions in clothing, water discharge, etc. So sometimes the "1 min left" indication can stretch into many minutes. In theory, at least, it's possible your machine just needs to be left alone until it finishes whatever it's doing. However, one would think that any issues not resolved in 10 - 20 min are an indication of a problem. So i guess that's my next question, did you wait long enough? Keep in mind i am not a kenmore expert.

Put it at finish. Unplug it for 5 min and replug it in. The door has a time delay on it! If not, try putting it at spin!

"F21" is a Long Drain error. If the drain time exceeds 8 minutes this error code will be displayed. In addition, a "SUDS" error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:


1.First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
2.Check the drain hose to make sure it is not kinked or clogged.
3.Check the electrical connections to the pump and ensure the pump is running.
4.Remove the drain pump filter and check for foreign objects and/or debris.


If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump.

Replace the timer, this is very easy. Un plug, remove access panel in the back and un plug the timer. This will be connected right behind the knob. It will be screwed down in front as well. Call your local dealership and get replacement part.

The timer is only an estimate. pull the botttom cover of the front of the machine. There is a cleanout on the water pump, if its clogged it could be the cause of your timer taking so long

This is really not uncommon. The more and more sophistocated the machines become, the more small decisions they make on their own. I have seen a one hour load take up to 2.5 hours.

If a load is off balanced, it will change the time. If the spin cycle doesn't spin enough water out, it will increase the time, and may still be too wet. (In that case you need to clean out the lint/drain trap.)

If you really want more control and quicker washes, there will be a setting like "Quick wash " or "Fast wash." Theis setting is quite basic and does exactly what you tell it to do, and you can always add and extra rinse, or higher speed cycles.

Kenmores and GEs are the highest reported rate of longer times. Relax. The more you add, ie, delicate, two rinses, light spin, medium dry, the longer it will take. It's just trying to do its job! :)
