Some Uncommon and Unexpected Symptoms of a Flakey Speed Control Board in Older Frigidaire Front Load Washers
kenmore model 417..... made by frigidaire
you say you caught the machine filling and draining endlessly?
known frigidaire problem
you need a speed board, also called the motor control unit
and yup a bad speed board can do all sorts of flakey stuff
another symptom .... timer knob gets stuck at around the 5 o'clock position
another common problem i saw with these machines.... the tub can go out of balance bad enough to smash into the bottom of the timer.
Remove washer lid, closely examine the bottom of the timer and where that molex plug connects there, look to see if it looks squashed or out of place
but filling and running the drain pump forever is the speed board for sure
frigidaire blamed this on electrical interferance comming from other outside sources, they say they modified later boards to prevent this
this was like 10 years ago or so

DSI Monitoring System:
When power is applied to the range, a safety delay of 40 seconds takes place before the direct spark ignition control becomes operational. The 40 second delay allows any unused gas inside the oven cavity to dissipate before a spark is activated. When the Bake or Broil operation is activated, the direct spark ignition control initiates an “internal self-test” and “flame safety check.” The flame safety check takes place anytime there is a flame present at either oven burner.
The self-test checks both solenoids on the gas distribution valve to verify that they are properly connected. If they are not, the control will turn the oven off, or lock it out. If the test is successful, the control will then open the appropriate valve, and initiate sparking at the
burner ignitor. Both the bake and broil ignitors spark simultaneously. Sparking will not occur until the gas distribution valve opens.
Once the gas has ignited, the “flame safety circuit” will monitor the flame at the burner to make sure it is present. If a flame is not present at the burner:
a)The control will allow the ignitor to spark for 4 seconds.
b)A 40 second delay to dissipate any unused gas inside the oven will occur.
The ignition attempt will occur three times. If the burner does not ignite after the three attempts, the system will “lockout”
The control will perform an oven system lockout if:
a) Any of the self-test checks fail.
b) The oven fails to ignite after three ignition attempts.
c) A flame is present within the oven for more than 10 seconds after the gas valve is off.
d)The flame is unexpectedly lost for any reason after being established.
If this occurs, a lockout condition will occur after 30 seconds with no attempt to reignite.
During the lockout, the gas distribution valve and ignition are turned off. All lockouts can be reset by pressing the OFF/Cancel keypad on the Electronic Oven Control.
NOTE: There will be no indication on the electronic oven control display showing a lockout condition.

Boot Camp Booty: Using the Schematic Diagram to Troubleshoot a Whirlpool Front-Load Washer that Won’t Run
Using the Schematic Diagram to Troubleshoot a Whirlpool Front-Load Washer that Won’t Run
Obviously, I can't speak to your knowledge or experience because it's not something that I have any first-hand knowledge of myself. I can, however, give you an idea of what the Boot Camp teaches in the form of a self-evaluation quiz that you can use to see what you know relative to what Boot Camp graduates learn and know. You can get this in our Sample course.
Just log in to ApplianceTechBootCamp.com and click the "Sample" tab in the upper menu. Once in the Sample course, click the "Sample Course Self-Assessment Exam” unit link in Module 2. But, again, you must be logged in at the Boot Camp site or the link will not be clickable.
Also, please note that your login at the Boot Camp site (ApplianceTechBootCamp.com) and this site (Appliantology.org) are different because they are two completely different websites running two different software packages and with two different registrations.
Based on the outcome of the exam, you can do an honest self-assessment of your skills to determine whether or not the Boot Camp would benefit you.
