The access door will not open, it is showing the locked symbol in the window

5.5 Opening The Door (from user manual)

While a program or the 'Delay Start' is
operating, the appliance door is locked and
the display shows the indicator 'key symbol '.
First set the machine to PAUSE by pressing
the "Start/Pause" touchpad. Wait until the
door lock indicator 'the key symbol ' goes off, then the
door can be opened.
If the door lock indicator 'the key symbol ' does not
disappear, this means that the machine is
already heating and the water level is above
the bottom edge of the door or the drum is
turning. In this case the door CAN NOT be
opened.
If you can not open the door but
you need to open it you have to
switch the machine off by turn the
program selector knob to the
position " 0 " to deactivate the
appliance. After about 5 minutes the
door can be opened.
CAUTION !
Pay attention to the water level and water temperature.

Hi Maire,
The door cannot open when the lock symbol is showing. Check your owner's manual for fault finding tips.

This is the keypad lock (symbol looks like a padlock?). Find the button that has a padlock symbol near it, hold down for 3 seconds, should unlock your keypad. This should be described in your user manual if not indicated on the touchpad.

If you use whats called a slimjim and slide it down on the far left outer side of the window you can access the accuater lever or rod for the door. Any autozone are police officer can show you exactly how to do it. It's real easy.

This normally means the that it has locked the door to stop an children opening it while it is washing. If it did not lock the door, a child could open it and burn themselves on the hot water.

Hi from retired Englishman in SW France,

The symbol indicates there is a problem with the door lock. Either the locking solenoid or the door lock sensor is malfunctioning and requires attention. Sorry- Service call!

inside the mechanical lock (The part that actualy holds the door shut when you close it) there is a switch that informs the control unit that the locking mechanism is either locked or unlocked. (door open or closed).

These switches fail sometimes, when this happens the control unit is not aware that you have closed the door
If the faulty switch is not informing the control unit that the door is closed, the central locking will not try to lock the door (because it thinks the door is still open).
The switch is integral with the lock unit, and they are not easy things to replace either.
remove the internal door trim. unplugg the wiring inside. remove the outer key barrel and unhook the cable from the outer handle to the lock unit. unbolt the lock unit. the window regulator will have to be unbolted from the window (remove the 2 plastic circular access panels and wind the window down to a level at which the 2 bolts are visible), lift the window clear once unbolted (using your hands, slide it upwards in its guide rails, stick it in place with tape).
once this is done the window regualtor can be unbolted (10 or so bolts) and removed, complete with the door lock.

Assuming child lock is not on...Water not fully going away/ blockage @ filter.

What is the Manufacture of the machine and the model number.
Without this information, there is no way to supply any suggestions.
Get back to me with those 2 items.
Thanks
