The machine recently started making a loud ticking noise when washing. It appears that the lower wash arm is hitting the back plastic water feed cover. It is like the arms are sitting lower than they used to. I've taken the arms off and nothing seems to be out of place. I'm wondering if some spacer has broken although there are no plastic bits sitting in the bottom. Any suggestions?

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.
With your dishwasher empty, roll out the bottom rack. The feed line for the upper spray arm runs from a pump outlet directly behind the lower spray arm spindle. This tube runs up the back wall of the dishwasher and mates with the upper rack when it is pushed in.
This feed tube simply snaps into place in the bottom of the machine. It is a high pressure line that makes an immediade 90-degree bend towards the rear of the unit. They have a tendency to pop out. When and if it does pop out you get almost no water coming out of the upper arm and you lose effective pressure in the lower arm, too. The cure is to push that feed tube back down firmly into the port until you hear it snap into place. While you have the lowere rack out it is a good idea to clean the intake screen out and check for any debris in the intake well.
Make sure that that upper arm is free to turn. Check it while you have dished installed, because sometimes, dishes on the lower rack may stick up too high and hit it. Otherwise, check the back of the water-supply tube attached to that upper rack.... Is it lining up with the water feed port or hole at the backof the dishwasher? Is there a gasket that is either ripped or missing? And check that wash arm carefully.... Might it be split or bent? Are the holes on the bottom clear? (Those holes are usually angled to push the arm around; if they are clogged, the arm won't rotate.)
Ensure that forks or other cuttlery is not poking out the bottom of the basket and obstructing the lower wash arm. Check to see that the lower arm is receiving water(and not blocked) to do this empty the machine and put a plastic bag around the arm that engages with a socket on the back of the washer this will block water to the upper arm and increase the pressure to the lower arm. Set the machine to rinse when you can hear the machine start to work open the door quickly and see if the lower arm is spinning!
Check the stainless steel cover on the bottom of the lower rack sprayer. If it has been bent downward on either end, it will hit the inside panel of the door near the bottom. It may score the panel as it hits on each rotation of the sprayer.
Just bend it back in position, carefully, with a pair of pliers. The technique required is similar to bending the pocket clip of a fountain pen back into the proper position after it has been sprung out too far. You might practice on a pen or mechanical pencil clip to see what I mean.
If your dishwasher seems noisy, check these:
Water-inlet valve Motor Heater fan Pump Water-inlet valve
An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.
If it's the motor that's noisy, either of these may be the "culprit:"
As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).
If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.
If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.
Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.
To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris. thanks and accept the solution accordingly
A common problem with noises from washing machines has been the under wire that may come out of small clothes. In the washer they can get stuck in one of the inner basket holes and make a scrapping noise, they can actually make there way into the pump and jam the pump, or make a terrible noise when the pump is running. Grab a flash light and have a peek inside the washer for this. Front load washers seem very common to this happen! If the tiny cloth is showing signs of fraying, may be best not to wash it in the washing machine, replace the cloth.======= It's noisy
Most noises from a washing machine occur during the spin cycle. If you hear loud thumping during the spin, the load of clothes may have become unbalanced. Stop the washer and redistribute the clothes, then re-start it. Repeat these steps if necessary.
you an remove lower access panel run d/w and nextime it makes the noise grab a flashlight and take a look under. sounds like a vibration issue( especially since you hit it nad it stops) perhaps your copper water line is rattling or your drain line is hitting motor causing noise
have you lowered the top basket into the lower position? if so the spray arm will knock the cutlery /plates. it sounds as though it is a spray arm problem. remove them and put it in wash to see if the noise goes. if not there may be an obstruction in the wash pump, this is a stripdown job then.
