Won't Start - Beep-beep-beep

do this and fix it. God bless you
However read the instr. manual section troubleshooting /
if doesnot have download from www.fitness.manualsonline.com
The processes below will get most controls unlocked.

Duet Washer - Press and hold the END OF CYCLE SIGNAL button for 15 seconds.

Whirlpool Duet Dryer - Press and hold the END OF CYCLE SIGNAL button for 15 seconds.

Kenmore Elite Washer - Press and hold the DRAIN/SPIN button for 15 seconds.

Some Models- Press and hold the control lock button for 15 seconds.

If none of these work try unplugging for 5 minutes

II might need the actual model number. However, you can go to page 9 on this manual and check if the flashing options can fix the problem. I am assuming you have already tried to turn the power off and back on.

The ohter thing to try is the reset sequence. Within 6-7 secs press High Temp/ Heat Dry/ High Temp/ Heat Dry/ High Temp/ Heat Dry. All lights should light up, press Start button to exit.

The control board has detected an error. Press any button to wake the machine then wait for 5 seconds. Press and hold the START/PAUSE and CANCEL buttons simultaneously then the failure code will appear in the display as an "E" followed by two numbers, a number and a letter or two letters as long as the buttons are held. The control will beep and the Door Lock, Wash, Rinse, and Final Spin indicator lights will flash. Post back the code for further advice.

This machine is know for the control boards going out. Here is a link to better explain it to you.

So I understand the issue. Does the wash cycle start up? By that I mean if you release the washer top from the base do the tumblers turn once the water fill cycle is complete?

If you don't have the FAV6800A/FAV9800A Service Manual (you can't get it on line anymore) see this post Clutch Fix I describe how to release the washer top from the base to observe the wash basket. Don't raise during the water fill cycle wait till that completes.

Does the key pad beep as you press the other cycle select key pads?

This could be a Control Board issue...........Rich

PF is Power Fail, means the Power was cut off. PF Power failure Power to the machine has been lost during the last cycle. This may occur on start up of a new machine due to factory testing.

hope this helps

The Service Manual for reference. Sears Parts Direct for reference.
I have tried to work with a few folks on this issue never received feed back to resolution see this post. I feel the issue is caused by one of three possible issues.

A stuck key issue/defective Spin Cycle key making constant contact forcing the Key/LED to cycle thru the Spin Cycle settings. Under normal conditions if you press and hold the Spin Select key it will cycle thru the settings, yours has a mind of its own (defective issue).

A false signal from the Control Board for the Spin Cycle.

A corrosion path issue at the Membrane Pad ribbon cable socket connection between pins 5 and 4. See page 20 of the SM button functionality “Spin” key.

Try to verify that the spin cycle membrane key is not stuck/defective signaling the Control Board to cycle thru the spin settings. I have not experienced this issue but let’s try the Membrane Pad Test to get a start point. See the Service Manual page 15, I have modified the process to make it a bit more understandable at least for me. Make sure the two digit display is not On or Lite.
Press the off button first so there is nothing displayed in the Two Digit display of your FAV6800AW.

Now Enter / Exit Service Mode

To enter Service Mode press the Enviro Plus and Spin Only keys for three seconds or until the control beeps. While in Service Mode, pressing the Presoak key will start a membrane switch check that verifies switch operation.

All the LEDs (except Presoak ) can be toggled or slewed by pressing the key associated with the LED or set of LEDs. Do not press the Presoak again during this test.

Press each key once and only once including the Signal Key the on side and the off side, also the UP and Down Arrow key of the LED display. All keys (including the OFF button) must be pressed within 5 minutes for this test to pass. “PA” will be displayed for five (5) seconds once all keys have been pressed and the test is completed (more like PA will be displayed for only a few seconds on my FAV6800AW). Following 10 seconds of inactivity at any point, this test will exit without any display. Let us know the results.

See my additional comment this board has message limit issues.

i have maytag neptune wash,modelo mah5500bww,my problem is: no starting,flashing start/pause button,after ten minutes is off.And now is ready for start when press start/pause button

Check latch mechanism for alignment. Often operation of machine loosens latch mechanism causing internal switch for "door open (or ajar)" preventing rinse or spin cycle. Opening and closing door presses latch mechanism closing internal switch allowing for continue processing to rinse or spin cycles.
