Hey everyone. I have a Whirlpool washing machine that I bought less than a year ago. It decided to continuously make training sounds while I was doing a wash. The lid wasn't locked and I had to unplug it because it wouldn't stop making that draining noise. Now all the lights flash and I can't get it to do anything. Any ideas? I have a technician coming next Tuesday but if they say it's something I did, I will owe close to $200 which I cannot afford. I seriously don't know how I did anything though. Put clothes in and push start. How can I have messed anything up? Help!!!
