The main control appears to be working fine. The 'play' symbol is on during the wash cycle i.e. before the door is closed having selected a program. When the door is opened after the cleaning has completed (either immediately after completing or hours later) the 'play' symbol is no longer highlighted which is what I would expect.
The only light that remains on is the main program light which again is what I expect prior to asking that program to run again. When the door is opened the steam will rush out and can be stopped by pressing the power switch to off.
I would need to test it to make sure it but I recall in the past on at least one occasion without a program running and with the unit fully cooled down, if I simply switch the power on the unit sounds like it is trying to start steaming even though the 'play' symbol is off.
