Cycle faults on an Amama dishwasher are timing faults: the control is waiting for a condition, and the useful question is which one, on an Amama dishwasher of any age. The order below starts with drain restricted, so the machine repeats a stage. The page is written to be worked through in order, and it names the point at which owner diagnosis ends.
What it looks like from the outside
- Runs much longer than its stated time, in detail — In practice, extended cycles usually mean the machine is waiting to reach temperature.
- Behaviour started after the door was opened mid-cycle, in detail — It clears with a cancel and drain.
- Cycle ends early with dishes still dirty — In practice, a short cycle that completes points at a program selection or a sensor.
- Drains repeatedly without progressing — In the common case, the machine is protecting itself.
Ranked causes on an Amama dishwasher
- Drain restricted, so the machine repeats a stage — what it looks like — Start here: it repeats the drain rather than failing outright. It takes the top place because no other cause here is both this common and this easy to test. Watch whether water level falls during the drain phase.
- Water supply restricted or valve partly closed, in detail — Start here: a slow fill makes the machine wait, and the cycle stretches or stalls. It falls here because the entries above it come up more frequently, though this one is far from rare. Check that the supply valve is fully open and listen to the fill.
- Incoming water too cold to reach temperature — A long pipe run from the water heater causes it. This rank reflects frequency rather than severity: the causes above are more likely, not more serious. Run the kitchen hot tap before starting and compare the cycle length.
- Program selection or delay start misread, in detail — It is the cheapest cause to eliminate. Select a standard program deliberately and watch it through. It ranks in the middle because it is common enough to check early and not the first thing to likely candidate.
- Door opened mid-cycle leaving a held state — From experience, the next program then behaves oddly. Note whether the trouble began after an interruption.
The diagnostic order
- First: drain restricted, so the machine repeats a stage — It ranks here because the causes above it explain the same symptom more frequently. Watch whether water level falls during the drain phase.
- Second: water supply restricted or valve partly closed — This step follows the one above because the two share a symptom and only one of them survives it. Check that the supply valve is fully open and listen to the fill.
- Third: incoming water too cold to reach temperature — It is placed here because everything above it is cheaper to eliminate and more common. Note whether the first wash of the day is the worst.
- Fourth: program selection or delay start misread — Read the panel for a delay indicator before assuming a fault. It sits here because it removes the largest group of causes for the least effort.
Checks you can make safely
- Cancel, drain and reset — Run the cancel and drain function, then remove power for several minutes before starting again. This clears held states left by an interrupted cycle.
About 15 min
- Check the water supply — On this build, verify the supply valve under the sink is fully open and the hose is not kinked. The fill should sound steady rather than hissing.
Tools: TorchAbout 15 min
- Clear the drain path — On this build, clean the filter and sump, then check the air gap and run the disposer. Switch the power off before reaching into the sump.
Tools: Gloves, BrushAbout 25 min
- Note exactly where it stops — In the field, a repeatable stall point is the single most useful thing to tell a technician. Run one full cycle and write down the elapsed time and the stage where it stalls.

Before you open anything
Safety
Isolate the machine and close the water supply before you inspect anything. 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.
Owner fix or service call
Book a visit if the machine never reaches temperature, since cold washing is both a cleaning and a hygiene fault. Past that line the useful thing to do is book the visit and bring the notes from these checks with you.

What is missing here, deliberately
This is generalized information. It applies to the fault class on this brand and appliance rather than to a single production family. Where a model differs, the difference is usually in the panel and the part numbers rather than in the physics of the fault. There is no model-level page for this Amama 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 amama-dishwasher-problems.
