What this usually is
Before anything is replaced, establish whether water is reaching the top rack at all — on these models that single observation resolves most of the list. A clogged filter recirculates the debris it just removed, and a spray arm with blocked jets leaves a shadow on the rack. Work the list in order and the expensive suspicion usually never comes up. The second column is the family key, and the first is what the rating plate will say.
What comes out of the machine
- Detergent left caked in the dispenser at the end of a cycle — The dispenser opened and nothing washed the detergent out, or the water was too cool to dissolve it.
- The cycle is much shorter than it used to be — Some machines shorten a cycle when they cannot heat. A short cycle with cool dishes is a heating story.
- Gritty deposits left on everything in the machine — Debris is being recirculated rather than removed, which points straight at the filter assembly.
- NEAR MISS — there is standing water in the bottom — That is a drainage fault and it has its own page for this family. It also produces dirty dishes, from the other direction.
The ranking for this platform
- Filter assembly blocked — Top of the list by a wide margin. The machine returns its own wash water to the spray arms through this filter, so a full one delivers last week's debris back onto clean plates under pressure.
- Spray arm jets blocked, or an arm that cannot turn — Second. Scale closes jets from the inside where you cannot see it, and one tall item hanging through a rack will stop an arm for an entire cycle.
- Loading faults — overlap, shadowing, blocked arms — Not a failure at all, and responsible for more complaints than any component on the list. Items nested together present one surface to the water and hide the other.
- Circulation pump or diverter fault — Bottom of the list. A pump that cannot build pressure produces a consistent dead zone, and that is where owner diagnosis ends.
- Body: On these models the upper spray arm is fed through a tube at the back of the tub, which is why an arm fault ranks above a pump fault here.
The diagnostic order for this family
- Take out the filter assembly and look at it — If it is loaded, that is the answer and the rest of the page is academic. Rinse it under a tap and run the machine empty.
- Run one cycle with the racks out and a cup of water on the base — Removes loading entirely as a variable, which is the commonest cause and the hardest to see.
- Feel the door and the outer panel partway through the main wash — A machine that never warms is a heating fault wearing a cleaning fault's clothes.
Before you open anything
Safety
Before any panel comes off, take the power away at the plug or at the breaker. A capacitor can hold a charge after the power is off, which is why the order is isolate first and open second. The filter chamber often collects glass fragments and other sharp debris. Rinse it under a running tap rather than picking it clean with bare fingers, and empty the sump by hand only once you can see what is in it. Checking your listing against the table takes a moment and saves ordering against the wrong catalogue.

When to call a technician
Stop at the point where the machine will not heat. A dishwasher that fills and runs but never gets hot has an element, a thermostat or a control fault, all three of which are tested with a meter on a live machine, which is not owner work.
