Baumatic BDW11 not filling with water and starting cycle

Hi I hope someone might be able to help… I’ve got a Baumatic BDW11 and when you chose the cycle and close the door, it just gives an error on the display (three lights lit up to the left) and beeps 3 times repeatedly. I’ve checked under the dishwasher and the floor is wet but I haven’t pulled it out as yet. Any help would be great!!

many thanks
