Beko DL1043W Dishwasher, Serial number: 12-500399-05. Just bought this dishwasher yesterday, plumbed it in and tried to do a run through cycle b4 using it. After a while, realised it had filled with water but hadn’t drained, then realised drainage cap was still on the sink, so removed it and the water drained away. But, ever since then it is making a noise that just wont stop unless the machine is off completely, and it wont do anything. Even when its turned off and on again the noise starts straight away. Have tried cancelling the programme but the noise continues and the machine wont do anything. Any help????
