Dishwasher Is Noisy During Drain Cycle – What To Check?







My Dishwasher Is Noisy During The Drain Cycle. I start a wash cycle on my dishwasher and when it is time to drain the water out, it makes a loud noise. My usually very quiet dishwasher goes through the wash cycle, drains out the water, and now it constantly makes noise. The noise sounds like a loud rubbing, humming, or grinding sound. This happens no matter what setting I have my dishwasher set on. If I run a quick wash or a long wash with heat, it still makes the noise when it comes time to drain out the water. My Samsung dishwasher is 3 years old and the noise has just started in the last month. What would cause the dishwasher to make this noise ONLY when it drains out the water? FYI: The water does drain out of the dishwasher, however the noise is always present.
