A new noise from an Amana dishwasher is usually something loose in the sump or an arm hitting the load, and both are found in the first ten minutes. The ranking begins with glass, a seed or a bottle cap in the sump. Everything here can be done with what is already in the house, up to the point where the page hands over to a technician.
The observable symptoms
- Rattle that changes when the door is pressed — In the common case, a panel or the kickplate resonating gives a rattle you can change by hand.
- Grinding that comes and goes during the wash — On an Amana dishwasher in ordinary household use, intermittent grinding is debris being picked up and dropped by the pump.
- Loud buzz only during the drain phase — More often than not, a drain-only noise belongs to the drain pump or a restricted hose.
- Humming with no water movement on an Amana dishwasher — On this build, it is the one sound worth stopping for.
The causes, in likelihood order on an Amana dishwasher
- Glass, a seed or a bottle cap in the sump — Start here: broken glass is the most common object of all. Remove the filter and search the sump well with a gloved hand and a torch. This one comes first because ruling it out is free and it accounts for the largest share of cases.
- Machine not level or feet on a soft floor — In the field, vibration passes into the cabinetry and amplifies into a buzz. Inspect the level across the tub base.
- Loose kickplate, panel or rack fitting — In practice, a fastener that has backed out lets a panel drum. Inspect the rack rollers and the arm mounting nut.
- Wash pump bearing worn, in detail — More often than not, a rising whine that grows over months is the one noise that needs a technician. Rule out debris and arm strikes first. This rank reflects frequency rather than severity: the causes above are more likely, not more serious.
- Spray arm striking an item or a rack, in detail — In practice, it is the classic rhythmic knock. Re-load the tall items and run again to confirm the change. This is the final entry because it is the expensive answer, and the inexpensive ones come first.
What to check, in order
- First: glass, a seed or a bottle cap in the sump — It follows because the answer above narrows what a result here can mean. Look for a chipped glass in the load that lost a piece, in most households.
- Second: machine not level or feet on a soft floor — This check earns its place by being fast and by eliminating an expensive possibility. Press each corner of the appliance and record whether it rocks.
- Third: loose kickplate, panel or rack fitting — Inspect the rack rollers and the arm mounting nut. The position is deliberate: done earlier, the result would be ambiguous.
What you can do yourself
- Check the spray arms against the load — On most units, do this before running any diagnostic cycle. Spin each arm by hand with the racks in place and note anything it touches.
About 10 min
- Time the noise against the cycle — In practice, run a short cycle and write down when the noise starts against fill, wash and drain. The phase narrows the list faster than any inspection.
About 15 min
- Steady the machine — On most units, a appliance held only by its feet on a soft floor will always be loud. Level the appliance and check that the mounting screws to the counter are tight.

- Search the sump — Switch off the power, remove the filter and sweep the sump with a gloved hand and a torch. Wear a glove; glass is the usual find.

What to do before any check
Safety
Isolate first, then look. Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never restore power while there is standing water under the machine.
Do it yourself, or book a visit
Book a visit if the appliance hums without pumping after the sump has been cleared. Beyond that point another owner test adds nothing that a technician will not measure directly.

Scope of this page
This is generalized information. It applies to the fault class on this brand and appliance rather than to a single production family. What a model-level page would add is the exact code list, the exact panel and the exact parts; what stays the same is the diagnostic order. There is no model-level page for this Amana dishwasher at the moment. If one is added, it will be linked from here and should be trusted over this page. The other problem pages for this appliance are indexed at amana-dishwasher-problems.
