Step by step
-
1 Fill the rinse aid and set it high
The unglamorous fix that works. Fill the dispenser, set its dosage to maximum, and give it two weeks of loads. Rinse aid is how modern dishwashers dry.
-
2 Use the heat/extra dry option
Eco and quick cycles skip heated dry on many machines. Turn on the heated dry, extra dry, or sanitize option and compare.
-
3 Open the door at cycle end
Condensation dry machines (Bosch style, no exposed element) benefit hugely from cracking the door when the cycle ends, some do it automatically.
-
4 Check the heating element (exposed element machines)
If dishes AND the tub interior are cold at cycle end, breaker off, then continuity test the element at its terminals under the tub, open circuit means replace it.
-
5 Load for drainage
Cups angled, plastics up top, nothing nested. Water pooled in mug bottoms isn’t a machine fault, it’s geometry.

| F9 E1 | Drain fault |
| F7 E1 | Heating fault |
| F6 E4 | Inlet fault |
