Hi,
Did you try the magnet on the lid lock assembly? Also hold a small piece of metal that is attracted to a magnet on the front/bottom /center of the lid itself to see if you can feel the presence of a magnetic field in the lid.
I just wanted you to try the magnet on the base (lid lock assembly) and a piece of metal on the lid (lid lock striker/catch) but that is OK.The following is the machine control diagnostic routine. Please unplug the machine for 1 minute, then plug it back in. Select ANY button except the start, power or stop buttons, then press and hold it for 3 seconds, release it for 3 seconds, press it for 3 seconds, release it for 3 seconds, press for 3 seconds.
Unfortunately , the most likely failure based on the results as you have described them is the user interface module.The part can be purchased from ANY part supplier using that number though. Now, to make things even more fun, This machine has had problems with both the UI board AND the combination central controller (CCU) motor controller (MCU) board.The manufacturer doesn't even give us techs a way to differentiate a failure of the UI from the CCU/MCU WHEN the system does not respond AT ALL to any user input. We usually have BOTH on hand and the manual basically says "replace one and if that doesnt work, replace the other" Yell
Now, based on MY experience, I have found that the problem is MORE likely to be the UI board in this case , only because there IS power to the UI, since you actually have lights, and this power comes from the CCU/MCU board BUT this fact alone is not enough to make a definitive diagnosis. If you have not seen any errors then that usually means that the lid lock system is ok, because if the boards are working, the controller knows that it sent a lock signal to the lid lock, or that the lid should be closed to progress the cycle but the circuit did not respond favorably, so an error is triggered and displayed on the display, usually "lid" will show on the display in this situation. With NO errors seen, power normal to UI module but NO response from UI module, the CCU/MCU board can be suspected which is where the errors with ALL other parts on the machine are sent, but then of course they are displayed on the UI. This is why we can only narrow the problem down to TWO possibilities in this case, not one.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
