Heat on an Amama dishwasher does two jobs, washing and drying, and a fault in one most often shows up in the other first. The order below starts with rinse aid empty or set too low. The page is written to be worked through in order, and it names the point at which owner diagnosis ends.
What you are seeing
- Greasy film returning on the load — In practice, a wash and dry complaint together points to heat.
- Cycle takes much longer than usual — Machines extend the cycle while waiting for temperature.
- Tub cold at the end of a cycle — Start here: a cold tub points to the element or its control.
- Plastics wet, everything else dry — That pattern is most often normal.
The likely causes in order on an Amama dishwasher
- Rinse aid empty or set too low — Without it a condensation dryer leaves everything spotted and wet. It ranks first here because it is both the most frequent and the cheapest to eliminate. Record whether glassware is also spotting.
- Program without a heated dry selected — Worth knowing: eco and light programs cut the heat to save energy. This rank reflects frequency rather than severity: the causes above are more likely, not more serious. Read which program is actually selected and its options.
- Heating element failed or scaled — what it looks like — In the field, it affects wash and dry together. Watch for heavy white deposit on the element if it is visible. It holds this position because the checks above it are quicker and eliminate more possibilities.
- Loading blocking drainage and airflow — On most units, cups and bowls that hold water will still be wet whatever the heat does. It ranks in the middle because it is frequent enough to check early and not the first thing to likely candidate. Angle bowls and cups and re-run.
- Incoming water too cold — Start here: it shows as long cycles and wet loads. Record whether the first wash of the day is worst. It holds this position because the checks above it are quicker and eliminate more possibilities.
- Thermostat or sensor reporting wrongly — Typically, the control stops heating when it believes the setpoint is reached. This one requires a technician to verify. It closes the list: reached only when every cheaper explanation has been ruled out.
The sequence of checks
- First: rinse aid empty or set too low — Record whether glassware is also spotting. This step follows the one above because the two share a symptom and only one of them survives it.
- Second: program without a heated dry selected — Read which program is actually selected and its options. The position is deliberate: done earlier, the result would be ambiguous.
- Third: heating element failed or scaled — This is the order because a positive result here changes what the next check means. Watch for heavy white deposit on the element if it is visible, as a rule.
Safe checks, in order
- Check the tub temperature at the end — Take care: the interior can be hot enough to scald, in ordinary use. Open the door at the end of a cycle and feel the upper tub wall, for a moment and carefully.
About 10 min
- Select a standard program with heated dry — Worth knowing: one comparison load settles the question. Choose the standard or normal program and enable the heated dry option, then compare the result.
About 10 min
- Fill the rinse aid — Start here: top up the rinse aid and increase the dose one step before the next load. Give it two or three cycles before judging.

- Re-load for drainage — From experience, angle cups and bowls so water runs off, and leave space between items. Open the door at the end to let steam out.
About 10 min
- Prime the hot water — A cold first fill costs heat for the entire cycle. Run the kitchen hot tap until hot, then start the appliance at once.

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. Do not use drain chemicals in the machine; they damage seals and plastic.
The line between the two
Rinse aid, program choice, loading and supply temperature are owner work; a failed element, thermostat or sensor is not. When the page runs out of owner checks, the remaining causes need a meter and a technician.

What is missing here, deliberately
The page is written at brand and appliance level, which means it holds for many models and is exact for none of them. 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. No family-specific or model-specific page exists for this Amama dishwasher yet; when one is published it will be linked here and will take precedence wherever the two differ. The other problem pages for this appliance are indexed at amama-dishwasher-problems.
