I ordered a IWL12 Console P/N 420722P 420374 420374009424 ASMN Software v27. The board and the console facia and overlay P/Ns 420155 426785 arrived today. I plugged it in and hit the start button and got a fault code 9. I looked up the meaning and swapped it for a newer version. It made no difference. I then tried the other solution and reset the size to the largest size by hitting Power+Fabric Care and saved the setting. I again attempted to start the machine. Then the water turned on and the motor started to turn then the motor stalled and as a result it drew too much current and completely fried the Motor Controller (LOUD SNAP AND POP SOUND ACCOMPINED BY BURNING SMELL). The display remained lit but the rest of the machine went quiet. What the F**K did I do wrong?? Is this a faulty/defective IWL12 console or Did I plug something in the wrong part and fried the MCU as a result? Please help. Glenn/DADoES Please email me your phone number if possible. I want to do this over the phone after this incident occoured!
 
Damage done

Display is fine but the MCU has some blown transistors. My dad worked in the recording studio and has had this happen many times before. My dad knows how to fix these boards. Thank god it wasn't the Eprom. And Also thank god that F&P used plastic tops. It could have killed me if it was a metal top and not grounded. LG and F&P "Direct Drive" Motors are capable of receiving or giving out 500VDC and who knows the amperage! I attached photos for Glenn. I wonder if WATER got into the board and toasted it due to the probe being pressed by the display board. Maybe it sprayed into the motor controller and fried it. Minimal damage was done and it scared the crap out of me. Hopefully I just made an error on my end and this will work or this machine will end up going to the shredder.

Probe Pressed?

I am talking about the thermistor probe that senses the water temperature coming in. I wonder if when I put the console on, I had the probe pressed out of the seal and it leaked and sprayed everywhere. I feel like WATER got to somewhere it wasn't supposed to be. DADoES I can email you my phone number. I would like a list of things to check. I have no clue why my board exploded.
 
OOPS

I figured out that this newest board was a PH7 board and not a PH6. I fried it because of the electrical differences and the PH6 Motor struggled with it then exploded. I have no clue why it was labeled as a PH6 Board when it was toasted when I put it on the machine. I attached pictures to compare and contrast. Message to DADoES and other F&P Enthusiasts and Experts. Don't make the same mistake that I made and don't judge a board by the labels. The cover was labeled a PH6 Motor controller but the board inside that I fried was a completely wrong PH7CPE Board. I'm going to try a PH6 Board and verify it this time. I will update if that one also explodes or if it works. The original is not being used until I know it's safe.

Ph7 boards are sometimes reflashed/revised to Ph6.  The original label silkscreened or laser printed on the board doesn't change.  The exterior label on the shell should be correct for what is it, and there may be an additional sticker label on the board for the revision.

Did you see evidence of water in the console or on/in the motor board shell?  The thermistor is not in a location to contact the display board.

What board/shell is in Reply 5 Pic 1?
 
 
Fabric sensing is a primary operational feature of Intuitive Eco, so generally agitation profile cannot be directly selected ....

Changing the soil level adjusts the agitation profile slightly higher or lower on the scale around the sensed "Normal."  Soil level can be changed after sensing is done, the profile name will change on the display scroll.  Wash time is also increased/decreased slightly on each step.

Manually selecting a higher water level than the load needs softens the interaction of the load with the agitator during fabric sensing for a gentler profile.  Creasables does this automatically by sensing the "normal" fill level and profile, then filling one level higher (but of course not higher than High) and re-sensing the profile.

A few options or Lifecycles engage specific agitation profiles (also temperature and sometimes water level which can be changed per-run but not saved to Lifecycles cycles):

- Wool runs a specific Wool profile but it may not be as gentle as expected.  Wool is the only cycle that does a Warm/Cold agitated rinse to match the default Warm/Cold wash temp.  Cold can also be selected (cold rinse).  Or Warm but I don't know if it does a Warm rinse or no more than Warm/Cold.

- Handwash does not run Eco Active, agitation is *very* gentle, two deep rinses.

- Lifecycle / Comforter runs a specific Comforter agitation profile and defaults to High water level, two agitated rinses.

- Lifecycle / Sports Shoes defaults to Medium/Low water level and runs a specific Shoes profile which is reasonably gentle and includes a soak period, two deep rinses.

- Lifecycle / Max Wash runs maximum agitation profile which varies slightly per the sensed or manual-selected water level.
 
 
Jerome,

Intuitive Eco doesn't operate that way.  It doesn't have buttons or a selector for Heavy, Regular, Delicate, etc.  There's one standard cycle.  Two up-down scroll buttons for "How Dirty?" to select the soil level (six choices).  A button "Fabric Care" with choices for Auto Sensing, Creasables (with Auto Sensing), Wool, and Handwash.  Auto Sensing is the default.  Normal operation the user turns on the power, changes the soil level if desired (mid-level is the default), then presses Start.  The machine auto-senses the water level, and auto-senses the agitation speed based on how the load feels and moves against the agitator fins.

Two other up-down buttons scroll through a choice of options.  Some are typical such as Temperature, Soak, and Spin Speed.  Others are unique to this machine.  Any of the options can be set as defaults for the standard cycle if the user prefers it as such for typical loads, and still adjusted for individual loads.

Another button scrolls through a list of 13 pre-programmed cycles that run temperatures and operational sequences for specific laundry situations such as various stains, Diaper Rinse, Sweaty, Muddy, Comforter and others.  Options can be adjusted for each run of a programmed cycle but not saved to it.
 
 
I've not found any service or operational information that lists the agitation profiles or provides any specifics on how Intuitive calculates the wash profile for a load.  The selected/running profile is stated by a name on the display such as Soft, Caring, Easy, Medium, Active, and others.  Increasing (or decreasing) the soil level adds (or removes) a + symbol to a given profile, then next steps to a stronger (or softer) action, and increases (or decreases) the wash time.  *Stained alternates several agitation and soak periods.  A given profile varies slightly per the water level regards to larger or smaller load size needing stronger or softer action to effectively move the items.

*The Soak option inserts a 2-hr soak period (or 1-hr with Time Saver) midway into the wash with a few agitation strokes every minute for the duration and a few mins of agitation after the soak.
 
 
Kelly, I assume you know how to access diagnostic mode (hold Lifecycle, press Power)?  Diagnostics on Intuitive can be accessed while the machine is running a cycle.  Press Power (once, carefully to not accidentally turn off / cancel the cycle if it's running) to exit.

Warning Status (non-fatal faults), Fault Status (fatal faults), and Machine Status (includes temp thermistor reading and the temp the machine wants to attain) are the three diagnostic screens.  Press Fabric Care to turn the pump on/off.  Press Home to toggle the diverter on/off.  Machine Status says Diverter Off or Heating or On or Cooling according to its state.  How Dirty Up runs hot water, How Dirty Down runs cold water (must hold the buttons).

There are a couple more displays that require a trick.  After getting into diagnostics, press and hold Lifecycle until it beeps again.  Press Lifecycle once more to unblank the display if necessary (pressing Lifecycle in diagnostics turns the screen on/off).  The two additional displays will be in the up/down scroll sequence.

Version Status details the display and motor board software versions .. and the motor RPM.

The other screen reports the water level value (WL) I think in millimeters of depth, and some parameters related to fabric sensing.  I don't know what they mean.

These extra screens usually remain viewable in diagnostics until the machine is disconnected from power for a minute.

Blanking the screen and pressing Option Down button brings up a Control Options screen.
- Restart flag (toggled via Home) ... normally enabled (highlighted) has the machine try to restart and continue the cycle after a fault occurs that may be momentary.  It may try to continue multiple times on a fault until it gives up and actually stops with the fault.  Reason to disable Restart is to faciliate a servicer catching a fault quickly without waiting for the restarts to time-out.
- Recycle flag (toggled by Adjust) ... normally disabled.  Enabling it has the machine repeat a running cycle indefinitely until turned Off.  This is to faciliate catching a fault that occurs erratically, or testing that a repair is successful by running repeated cycles.
- Hot Tub flag ... set to on by the control board whenever the hot inlet valve is run during a wash fill and restricts spin to no more than medium speed.  Automatically resets to off after a cold rinse occurs.  Press Option Up to manually turn off Hot Tub if needed to troubleshoot a problem.
