Hi,
Had similar on mine,
First off I did as the manuel said, pull plug from wall turn off water, wait 1 minute, reconnect ect.
This didnt sort mine so I unplugged again, turned off water, removed water pipe where enters the machine, removed the little filter type thing just inside the entry point ( it pulls out ) reconnected everything , fired her up and "bingo". Now, wether this sorted the problem or was a coincidence I dont know but it worked for me.
Good luck.
