SOURCE: The water pipes rattle violently in the beginning of the cycle.

My Kenmore 16464 dishwasher caused a buzz in the water pipes at the start of the cycle that I thought was just water hammer. It turned out to be a bad water inlet valve on the dishwasher that has water hoses (inlet and outlet) attached plus has an electrical connector. It is located near the front left underneath the tub. I pulled the dishwaher out and replaced it and all is quiet again. - Jim

I keep having problems with the salt. I have put it on a clean cycle twice. I have washed out the spray arms but everything is covered in salt which is hard to remove.


That isn't salt. That is residue from extremely hard water. A water softener will stop that build up and will help to remove that same buildup from the water pipes throughout the house and will extend the service life of your water heater.

Kenmore dishwasher making "spitting" or "sputtering" noise during operation


The easiest way to confirm if the arms are blocked is by turning all the arms in the machine to a certain same position and running the machine for a few minutes in its wash cycle. Open the door and see if the arms have moved. If not, check all the holes in the arms for blockages. Sometimes its very difficult to clean them. You may have to poke a pin or something into hole and then shake the obstruction out through the large inlet hole under the spray arm itself.

Why do my house pipes vibrate?


The problem is called water hammer it happens because water lines have become lose inside the walls. Generally because pipe straps have loosened or even broke, or not enough of them were used at time of installation letting pipes rattle against them selves or walls and so on.

Sink backs up with water when running faucet,dishwasher does not drain,all pipes under sink clear


We had this problem and found out that the pipe leading away from the house was clogged. Have a plumber look (with a camera) down your clean out, and see if that is the problem. They can snake it from the clean out and clear out tree roots or whatever is the problem.

Fridgeair dishwasher not working making loud sound. water comes in and I can make it drain out but washer does not start


Hello

bearings in the heater fan may get worn out or rust. If this happens, it may become very noisy, either grinding on the bearings, or scraping against the rust. If this happens you need to replace the fan motor. Sometimes, a fan blade may come loose, and you need to replace it.
Sometimes it's the motor that makes the noise you hear. The motor has bearings in it which may become worn or get rusty. When the bearings get worn, they allow the shaft to wobble which can get quite loud. If there is a spin seal leak, water may get inside the motor, washing the bearing grease away. If the spin seal is leaking, you'll notice water leaking from under the dishwasher. There is also a disc attached to the top of the motor called a slinger. It sometimes breaks off and spins around the motor's shaft while it turns, causing some noises. You will need to replace the motor if the bearings are bad. You also need to replace the motor if the slinger is broken as well.

Newer dishwashers may make a squealing or rattling noise on the first run. This is because it has not had any water in it yet, and the motor seals are dry. You may hear this in a unit that hasn't been run in a week or more as well. You should operate the dishwasher regularly to keep the sump water from getting smelly, and to keep the seals lubricated. You can add a quart of water to the sump before running it.

Rattling noises may be produced by dishes rattling inside the dishwasher due to the water pressure from the sprayer arms on the dishes. To determine if the rattling is a loading issue, run the unit empty. If the sound is persistent, it may be that there is debris in the pump.

dishwasher water-inlet valves are noted to make a hum that lasts about 60-90 seconds several times during a washing cycle. This hum is a different hum than the sound of the motor running.

A rhythmic knocking or thumping sound may be caused the sprayer arms hitting something as they go around and around. Rearrange the dishes and resume the wash.

A clunking or clanking may be heard when the detergent cup opens; while a clicking sound may be produced by the timer or electronic control panel.

A solenoid makes a snap sound when it opens. This happens about six times during each load.

Pipes rattling or banging may be caused by a water hammer effect. Water hammer sounds are caused by a valve closing in the system, and yet the water in the pipe is still flowing because of its kinetic energy. The sound is caused by the water slamming into the closed section of pipe. A plumber can install an anti-hammer device.

Small objects can sometimes get stuck in the pump. When this occurs, you'll need to open the pump and then remove the item that is making the noise or replace the pump. The dishwasher pump is usually mounted directly to the motor and runs off the motor as well. The pump is also attached to the bottom of your dishwasher.

Slog builds up in the drain pipe right before the garbage disposer. I had to replace mine when I replaced my old dishwasher. If you put vinegar in the dishwasher to unplug the pipe, the vinegar could have loosen all the slog and clog the drain pipe just like a built up in the hurt artery.

Lg dishwasher stops throughout the full cycle


If you are still having problems with your LG dishwasher, turn off the hot water supply to the dishwasher and remove the hot water inlet pipe (remove the lower, front panel (toe kick plate) )
Check the screen/filter at the water inlet on the dishwasher.
Reconnect the pipe and turn the hot water supply back on.
Test out and enjoy!

Loud rattling grinding noise when pump is running, no water enters the machine.


Make sure the water is turned on to the machine, if it is then it sounds like a faulty water fill valve, just replace the fill valve, they can sometimes be cleaned but I would never trust one, they can always stick in the on position later and flood your house. Check to see if the valve is geting 120v ac before replaceing the valve, if it's getting voltage and no water is flowing then the valve is bad. You will need to borrow or buy a multi-meter for this test.
