I took the washer apart. Found a You Tube video that showed me how to remove the front and then access the water pump. It was quite easy.
I removed the pump. The two water hoses attached to the pump where clear. I could easily blow through both and there was no obvious clogs.
I removed the motor/impeller assembly from the pump. Again no obvious blockages.
I tried blowing through the small black pipe that comes out to the front of the washer which is attached to the pump assembly.
It was completely blocked with very fine black particles. It looked like very fine sand. I used a skewer and removed all of the sand from the tube. I would say that 90% of the tube length was filled with sand.
I was washing off the impeller and when I put it down the water that dripped from it was also full of the same fine sand. So being careful not to get the motor wet I kept rinsing the impeller and more and more sand came out.
After about 15 to 20 min of rinsing out the sand, I noticed that the impeller would move in an out about 1/4". I did not notice that before.
I have assembled every thing and the washer is now operating.
The wash cycle started right away - did not sit and hum for 10 to 15 min.
Before I removed the sand from both the tube and the impeller the impeller did rotate freely.
Have you hear of this type of sand build up?
