The short answer
Judge heat by the results and by the incoming water before suspecting the element, because a long cold run to the kitchen tap produces exactly the same complaint.
What you observe
- Dishes cold at the end of a cycle
- Plastics wet while the rest is dry
- A greasy film that used to not be there
- The cycle running far longer than it used to
- Detergent left partly undissolved
- No warmth at the door at any point in the cycle
- Everything wet but the wash is clean — Means: a drying rather than a heating fault
- The cycle stopping part way — Means: a cycle fault
- A burning smell — Means: stop immediately — an electrical fault
Ranked causes
- High-limit or thermostat open — Position: first — Rank reason: the board on this platform stores and displays fault information, so it is read first — not because it fails first — Owner fixable: false
- Temperature sensor misreporting — Position: second — Rank reason: the board on this platform stores and displays fault information, so it is read first — not because it fails first — Owner fixable: false
- A cycle selected that does not heat much — Position: third — Rank reason: a connected platform has settings and modes that produce symptoms indistinguishable from hardware faults — Owner fixable: true
- Detergent unsuited to a low-temperature cycle — Position: fourth — Rank reason: a connected platform has settings and modes that produce symptoms indistinguishable from hardware faults — Owner fixable: true
- No rinse aid, so nothing dries — Position: fifth — Rank reason: a connected platform has settings and modes that produce symptoms indistinguishable from hardware faults — Owner fixable: true
- Incoming water cold — Position: sixth — Rank reason: the sensors and heaters this platform monitors are the components its faults most often point at — Owner fixable: true
- Basis: Ranked for the whole line, generalized across families.
Check in this order
- Establish whether your machine is front-control or top-control — Position: first
- Run the kitchen tap and time how long it takes to run hot — Position: second
- Check which cycle is being used — Position: third
- Feel the door and the dishes at the end of a normal cycle — Position: fourth
- Then treat the element and its protective devices as the suspects — Position: fifth
Owner checks
- Run the kitchen tap until it is hot and note how long that takes, then start the dishwasher immediately. — Position: first — Tools: none — Time: a few minutes
- Open the door and look at the top edge for the control panel, then check whether the outer door carries a cabinet panel rather than a factory one. — Position: second — Tools: no tools needed — Time: a few minutes
- Select a normal or heavy cycle rather than an eco or light one, run it, and judge the result against the usual complaint. — Position: third — Tools: none — Time: one cycle
- At the end of that cycle, open the door and feel the dishes and the tub wall. — Position: fourth — Tools: none — Time: a few minutes
- Fill the rinse-aid reservoir and run one more cycle before judging the drying separately from the washing. — Position: fifth — Tools: rinse aid — Time: one cycle
- Note whether cycles now take much longer than they used to; write down the actual behaviour for the technician. — Position: sixth — Tools: a notepad — Time: a few minutes
- Note: Times are given as qualitative bands, not measured values.
Safety
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.
When to call a technician
Call when the incoming water is hot, a full cycle is selected and the dishes are still cold at the end.
