Hi I am new here and need some help with my washer dryer.. a few nights ago when it was drying It was making a horrible nose so I turned it off.. today iv put a was on.. came in and the 4 lights were flashing.. not knowing what this was I turned it off and back on and re started the wash now about 5-10minutes later it has just stopped.. There is still water inside so I cant open it.. any advice on what the problem might be. Thanks in advance x
