Is Your Dishwasher Making Noise When Draining? Here’s Why and What to Do About It
Is your dishwasher making noise when draining? You have a reason to worry as a normal, properly functioning dishwasher shouldn’t make weird noises. Your dishwasher will make the unusual noises when:
There is something caught in the chopper
If your unit is making weird noises, chances are there is something caught in the chopper. I had a similar problem and when I opened the dishwasher, I found a glass pipe, a piece of paper, and a few washers there in the chopper and upon removing them, the unit started running quietly.
To get to the chopper assembly you have to take the racks out and remove the pump from the insides of the dishwasher.
There is something jamming the drain propeller
If your appliance is making rattling noises, there is something jamming the drain propeller. To confirm if this is the case with your unit, take the filters out and unscrew the screw in the base towards the left. You should then pull out whatever is lodged there.
The water intake line is kinked or faulty
If the water intake line is kinked or faulty, the dishwasher will make off-putting humming sounds. You should confirm if your valves are worn out or bad and if this is the case, replace them.
Tips to prevent your dishwasher from making draining noises
As you can guess, regular inspection and cleaning of the dishwasher drain pump and other parts will prevent the noises from coming about.
During the inspection, you are able to pick any materials that might have got into the dishwasher before they start raising havoc.
Sometimes the dishwasher will make noises and yet there are no materials caught up in the drain up or propeller. In most cases, this happens in cheap dishwashers.
If you have done the inspection and the appliance is in pristine shape, and it’s making the noises and you bought it at a huge bargain, chances are the noises are due to the low-quality appliance.
The only way to bring the noises to a stop is to get a better, higher quality, quiet machine.
