The short answer
On an AEG dishwasher, a cycle that stops or will not finish most often comes back to a drain the machine could not complete in time, with a fill that never reached its level close behind. AEG machines are current-generation European appliances: sensor-driven, code-reporting, and built around a base tray with a flood switch that will take the machine out of service the moment it sees water. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- a code or an indicator appears exactly when the cycle stops
- the machine stops part-way and stands with water in the tub
- the program time counts down and then stalls at the same point
- Not this fault: if it finishes but leaves water behind, treat it as a drain fault
Ranked causes on this platform
- Ranked for an AEG dishwasher, which runs a sensor-driven controller that reports a fault code on the display. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- A drain the machine could not complete in time — Why: This is the most common stall of all: the controller waits for the sump to empty, does not get it, and stops with water in the tub.
- A fill that never reached its level — Why: A closed supply tap, a crushed hose or a blocked inlet screen leaves the machine waiting, and it gives up rather than running dry.
- A base-tray flood switch that has latched — Why: On machines with a base tray, a trace of water there stops the program and locks the machine out until the tray is dry.
- A temperature the machine could not reach in the time allowed — Why: A weak heater or a wrong sensor reading stalls the cycle at the same phase every time, which is the signature of this fault.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- A drain the machine could not complete in time — Because: this is the most common stall of all: the controller waits for the sump to empty, does not get it.
- A fill that never reached its level — Because: a closed supply tap, a crushed hose or a blocked inlet screen leaves the machine waiting.
- A base-tray flood switch that has latched — Because: on machines with a base tray, a trace of water there stops the program and locks the machine out until.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Clear the filter stack and the drain hose, then run a rinse program and watch whether the sump empties. — Tools: a bowl, a brush and towels — Time estimate: allow half an hour
- Confirm the supply tap is open and check the inlet screen at the hose connection. — Tools: a spanner and a bowl — Time estimate: a quarter of an hour
- Look for water in the base tray and dry it before assuming any electrical fault. — Tools: a torch and towels — Time estimate: allow half an hour
- Note whether the stall always happens at the same point and whether the tub is warm at that moment. — Tools: nothing — Time estimate: one cycle
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Isolate the circuit before reaching into the sump, and treat the water in a machine that has just run as hot enough to scald. Never defeat the door latch to run the machine open; the latch switch exists to stop the wash the moment the door moves.
When to call a technician
Call a technician when the drain path is proven clear and the machine still times out, when the base tray refills after being dried, or when the stall follows the heating phase with a sensor that cannot be reached from the front. A machine that keeps stopping with water in it should not be left in service.
