Amana dishwasher unpleasant odor — recently moved into an apartment

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   If the smell is present now, cancel the cycle and leave the dishwasher off. Ventilate only if doing so is safe. If there is smoke, visible flame, a hot or melted plug, sparks, a gas-like odor, a leak near electrical equipment, or breathing/eye symptoms, leave the area as needed and contact the building's emergency or qualified service channel; do not restart the appliance.

   Expected result: The odor is food-like or musty with no heat damage, or it is burning/electrical/gas-like/sharply chemical or accompanied by smoke, heat, damage, a leak or symptoms.

   Next step: For any hazard sign, keep the dishwasher out of service and involve the landlord/property manager and qualified appliance/electrical or building emergency service. Do not mix chemicals or repeatedly reset power.

   Why this matters

   Why: The first group can proceed to an unpowered external inspection. The second group is a fire, electrical, exposure or water-safety concern and cannot be cleared by a cleaning cycle. Amana's charred-odor guidance specifically limits inspection around the heating element to a completely cooled dishwasher.

2. Check 2

   With the dishwasher off and cool, locate the model label and check the owner's materials or ask the landlord/property manager when the unit was installed and what products were used. Record the exact smell description and whether it occurs only during heating, at the door, under the sink or near the drain.

   Expected result: The unit is confirmed new and the smell matches hot tar/petroleum, or the unit's age and previous cleaning history are unknown.

   Next step: If new installation and the odor is only the described petroleum smell with no hazard signs, ventilate and monitor within the stated period. If the age, model or product history is unknown, keep the model information for the property manager or service provider and continue with the safe visible checks below.

   Why this matters

   Why: Amana's 4–6 week explanation is scoped to new dishwashers with sound-deadening material. A move-in date alone does not satisfy that condition, so an unknown-age unit should not be labeled normal from smell alone.

3. Check 3

   After the dishwasher is completely cool, inspect only accessible areas: the bottom of the tub, filter, spray-arm area, door gasket and the area around the heating element. Look for food soil, standing water, detergent film, melted plastic or charred debris; do not remove panels or touch wiring.

   Expected result: There is food or residue with no heat damage, standing water or drain connection issue, or there is melted plastic, charred debris, a damaged element area or unexplained heat damage.

   Next step: For ordinary residue, remove only loose accessible debris using the model's instructions and proceed to the cleaning decision. For melting, charring or damage, keep the unit off and arrange qualified service; do not scrape a hot element, energize it to burn residue away or replace an internal part by guesswork.

   Why this matters

   Why: Amana identifies food soils as an ordinary odor source and says melted plastic or food around the heating element should be checked only after at least 30 minutes of cooling. Visible melting or charring is not an ordinary cleaner-residue branch.

4. Check 4

   If the odor is food-like or musty and no hazard sign was found, clean the accessible filter/interior and gasket according to the exact model instructions. Amana's general cleaning article describes either a dishwasher cleaner or 2 cups of white vinegar in an upright glass on the bottom rack with the dry option off; use one approved method only and never combine vinegar, bleach, detergent or an unknown product.

   Expected result: The odor improves after the accessible residue is removed, or it remains unchanged, becomes sharper during heating, or returns with smoke, heat or a leak.

   Next step: Do not add another chemical. If the odor persists, changes to burning/electrical, or returns with a leak or heat damage, stop use and contact the landlord/property manager and qualified service.

   Why this matters

   Why: Improvement supports a surface food/residue or drain-path source, but it does not prove that an unknown chemical is safe. Persistence or a hazard change means the issue is not resolved by routine cleaning.

5. Check 5

   If the dishwasher drain is visibly connected to a garbage disposal, inspect the accessible sink/disposal area for retained debris or standing water. Amana says to run the disposal to clear debris and clean the dishwasher and disposal, but do not disconnect the drain hose or reach into the disposal while energized.

   Expected result: The smell is strongest at the sink or drain and there is visible debris/standing water, or the smell is strongest inside the dishwasher and the drain path looks clear.

   Next step: Use only the disposal's normal safe operation if the area is dry and clear; otherwise leave it off. If standing water, a leak or persistent odor remains, request plumbing/appliance service rather than opening hoses or panels.

   Why this matters

   Why: A disposal-connected drain can transfer odor into the dishwasher. A clear drain path makes that explanation less likely but does not identify an internal dishwasher fault.
