Bob---you'll need to identify which BOARD is at fault (DISPLAY or MAIN)
Press & hold both the SPIN SPEED & SOIL LEVEL buttons
Press the POWER button---and release all 3 buttons
Wait for the door to lock (single click sound)-----if the door does *not* lock------replace MAIN BOARD.
Look at the Control Panel---if all of the lights are *not* on/illuminated---replace the DISPLAY BOARD.
Press the START/PAUSE button the following number times to continue testing...
1--Tumble CW & Drain Motor Runs
2--Low Speed Spin
3--High Speed Spin
4--PreWash Valve
5--Main Wash Valve
6--Hot Water Valve
7--Steam Valve
8--Bleach Valve
9--Tumble CCW
10-Heater 3 Seconds
11-Circulation Motor Runs
12-Drain Motor Runs
13-Water Level Sensor/Steam
14-Steam Heater Test
My opinion is that the MAIN BOARD has failed.
Also---you can rule out the DISPLAY BOARD by removing the front CONTROL PANEL...
Remove the DISPLAY BOARD---and then reconnect the plugs (of the DISPLAY BOARD)---plug in the washer and while holding the Board in your hand---press the POWER button microswitch to "turn on" the washer---and then press the START button microswitch numerous times to rule out an intermittent START switch on the DISPLAY board.
If the washer begins a cycle (starts) intermittently---failed DISPLAY BOARD (microswitch)
Press & hold both the SPIN SPEED & SOIL LEVEL buttons
Press the POWER button---and release all 3 buttons

To eliminate:
Musty odor
L-O-N-G cycle times
Dingy/yellowing whites
Suds error message
Slow spin speeds
Intermittent water leaks (from rear of washer)
And other annoying symptoms which vary brand-to brand.
Read below:
The *correct* amount of HE (High Efficiency) detergent that should be used in any front load or agitatorless top load washer with tub sizes 3.0 cu ft and larger is as follows:
HE: (2) Tablespoons Per Wash Load
HE 2X: (1) Tablespoon
HE 3X: (1) Teaspoon
Perform a TUB CLEAN CYCLE every (4) months.
Use: "Tide Washing Machine Cleaner"
