When I push the start button sometimes the machine will start and sometimes I have to hit the button again. I have noticed the machine stop right in the middle of the water going in and stops. I then have to push the start button again and then it continues on.

I personally already replaced the a part on the panel it was blue something to do with the water pressure or level because the water was overfilling.

However, I am not sure if this is the start button or something else. I just need help figuring out what the problem could be and then figure what part I need to replace.
