I used to get the machine to run by holding down the normal button then releasing it. I then read about the pump having something stuck in it. I took it apart down to where you can see the slots that go in to the pump and found some small bones and tooth picks. Cleaned it out as best I could and put it back together. The normal light still flashes and now it wont come on at all. Please help. If I have to get further down into the pump then I will need some instruction how to do that. Thankyou
