Hi,

Unfortunately this would suggest a failure of the control board or display board.

Unplug the appliance and take the top off.

At the front right top you should see a control board hanging down into the appliance.

Disconnect the wires and plug them back on again.

Try the machine again.

If still not lighting up you'll need to replace the control boards to try and cure the problem.

Examine them closely (take them out to do this) and look for obvious signs of damage.

You may be able to narrow the fault down.

Check this out, see what you find.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
