An Amama dishwasher that smells is telling you where water and food are sitting between cycles, and the filter is the first place to look. First on the ranking: filter and sump holding food debris. 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 signs, one by one
- Dishes smell after a completed cycle — The filter is the usual source.
- Smell worse after the machine has stood unused on an Amama dishwasher — On this build, frequent use masks it.
- Musty smell when the door is opened on an Amama dishwasher — In practice, it most frequently builds over weeks.
- Sewer smell rather than a musty one — Start here: a drain smell points at the trap, the air gap or the hose routing.
Causes ranked for this build on an Amama dishwasher
- Filter and sump holding food debris, in detail — More often than not, it is the most frequent cause by a wide margin. It heads the list on this build: most frequent, and quickest to eliminate. Remove the filter and smell it; the answer is most frequently immediate.
- Biofilm in the door gasket folds — Worth knowing: it is the second place to look and the first people miss. Wipe a section with a cloth and check what comes off.
- Spray arms and interior scaled or greasy — Start here: grease films the interior and holds odour. Run a finger along the tub wall above the water line. It falls here because the entries above it come up more frequently, though this one is far from rare.
- Machine used too infrequently — In the common case, it is not a fault at all. Note how frequently the appliance is run. This rank reflects frequency rather than severity: the causes above are more likely, not more serious.
- Drain hose without a high loop or a dry trap — In practice, a trap that has dried out does the same. Run water in the sink to refill the trap and see whether the smell changes. It falls here because the entries above it come up more frequently, though this one is far from rare.
- Food left on dishes for days before a cycle on an Amama dishwasher — In the field, it is a habit answer rather than a appliance answer. It comes last because the causes above it explain the same symptom far more frequently. Rinse cycles between full loads solve it.
The sequence of checks
- First: filter and sump holding food debris — It ranks here because the causes above it explain the same symptom more frequently. Look at the sump well under the filter for sediment.
- Second: biofilm in the door gasket folds — Pull the gasket lip back gently and look inside the fold. It comes at this point because the check above has already ruled out the alternatives.
- Third: spray arms and interior scaled or greasy — It comes at this point because the check above has already ruled out the alternatives. In practice, look at the arm holes for grease and deposit.
- Fourth: machine used too infrequently — Note how frequently the appliance is run. It follows because the answer above narrows what a result here can mean.
What you can do yourself
- Run a hot maintenance cycle — On this build, repeat monthly if the appliance is used lightly. Run an empty hot cycle with a descaling and degreasing product made for dishwashers.
Tools: Dishwasher cleaner or white vinegarAbout 15 min
- Change the habit — As a rule, a appliance used daily rarely smells. Scrape plates properly and run a short rinse if a load will stand overnight.
About 5 min
- Deep-clean the filter and sump — Wear a glove for the sump; glass fragments are frequent, on an Amama dishwasher of any age. Remove the filter stack, wash it in hot soapy water with a brush and clear the sump by hand.
Tools: Gloves, Brush, Hot soapy waterAbout 30 min
- Check the drain routing — In practice, trace the hose and make sure it rises above the appliance before dropping to the waste. Refill a dry trap by running the sink.

Safety
Nothing below is done with the circuit live. 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
Call a technician when the filter, gasket, interior and drain routing are all clean and the smell returns within days. If you reach the end of the list without an answer, what remains requires test equipment rather than more looking.

Scope of this page
This page covers the class rather than the model. Panel layouts, code lists and part numbers vary within the same brand. Anything model-specific, including error-code tables and part numbers, belongs on a page for that model rather than here. At present nothing more specific exists for this Amama dishwasher. Any future family or model page will be linked here and will outrank this one. The other problem pages for this appliance are indexed at amama-dishwasher-problems.
