I pulled the dishwasher last night and removed the drain hose from the disposal and from the drain pump. I ran some water and air from a compresser through it and removed what looked like a flattened piece of plastic tubing (think a flattened drinking straw only wider and thicker). Water will flow through the hose but only at a trickle. The water was just from the kitchen faucet and it was not pressurized at all. I am thinking that the length of the hose and the up and down winding of it might now allow for a steady flow of water.
After reassembling the hose I started the dishwasher in rinse only mode and let it fill completely. After letting the water circulate for a minute or so I opened the door and cancelled the cycle, then shut the door. In the past this would cause the dishwasher to go through a drain cycle. This time, the pump did not even start. I checked the electrical connections to the pump and they were all secure. Is there a separate relay that send power to the pump or is it just part of the main circuit board? Is there a way that I can force the drain pump to start? I just replaced the pump less than a month ago, so it shouldn't be the pump (however i suppose it could be).
Lesguns - no the drain hose is not anchored toward the top of the sink. It never has been attached that way and I have not had this problem before. I can do that if you think that will help, but I really think there is another problem since the pump will not even start.
Any help will be much appreciated.
