The short answer
On a dual-badged machine, work out which heater design you have before deciding anything. The badge does not tell you; the rating plate inside the door does, and the parts catalogue is keyed to that plate rather than to the name on the front. After that the fault order is the ordinary one: a heat-phase trip is the heater, a machine that stops and pumps out is the anti-flood system.
What you observe
- Trips protection at the same point in every cycle — The heat phase. Which part that implicates depends on which heater the machine has.
- Machine stops and pumps out, will not accept a programme — Anti-flood float lifted by water in the base tray. Plumbing, not electronics.
- Trips the installation rather than its own circuit — Earth leakage — the signature of a heater whose insulation has failed in water.
- Ordered parts do not fit — The badge-era problem in its purest form: parts were matched to the name rather than to the rating plate.
- NEAR MISS — dead display and nothing tripped — A supply, door-switch or board fault, and a different page.
Causes, most likely first on this badge
- Heater leaking to earth — whichever design it is — First. On the integrated design the heater is part of the circulation pump and the whole assembly is replaced; on the separate-element design the element alone comes out. The symptom is identical — a repeatable trip at the heat phase — which is exactly why identification has to happen before anyone orders anything.
- Water in the base tray and the anti-flood response — Second. A weeping hose, door seal or sump gasket fills the tray, the float lifts and the machine refuses to run. It is the commonest reason a dishwasher of this era is declared dead while being electrically sound.
- Mains filter and connector ageing — Third. These machines are old now. Suppression components and spade connectors in a warm built-in cabinet degrade, and the result is a hot smell or a nuisance trip with no other pattern.
- Wiring harness damage from previous service — Last, and worth naming on a badge this age: machines that have been pulled out and pushed back repeatedly get cables trapped behind the plinth and hoses chafed against the frame.
Check in this order, and why
- Read the rating plate on the door edge and write it down — It is the only reliable identification, and everything downstream depends on it.
- Establish whether the machine stopped itself or the breaker tripped — Two different faults with one description. This question separates them.
- Note the exact point in the cycle the trip happens — Repeatable at heat means the heater; random means a connection or the filter.
- Look for water in the cabinet and under the plinth — Last owner observation. Beyond this the heater has to be tested, which needs a meter.
What an owner can safely check
- Switch off at the breaker, not at the machine — The supply point for a built-in machine is behind the cabinetry and is not meant to be reached in use.
About 5 min
- Photograph the rating plate inside the door — This single act prevents the wrong-part problem that dominates repairs on this badge.
Tools: phone cameraAbout 5 min
- Remove the plinth and look for water and staining — Dried mineral trails show where a leak has been running even when the tray is dry today.
Tools: screwdriver, torchAbout 15 min
- Check the inlet hose, drain hose and sink-trap joint — Most tray water arrives from a joint disturbed during other work under the sink.
Tools: hand toolsAbout 15 min
- STOP HERE — heater testing needs isolation and a meter — Insulation resistance cannot be judged by inspection, and this is a wet appliance.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Isolate at the breaker on a built-in machine rather than hunting for the plug behind the cabinet. Never defeat the anti-flood float to force a cycle, never re-arm a tripping breaker to finish a wash, and do not tip a machine with water in its tray towards its own electrics.
When to call a technician
Call when the trip repeats at the heat phase, when the installation rather than the machine circuit trips, on any hot smell, and when anti-flood keeps operating after the visible joints are checked. On this badge it is worth giving the technician the rating-plate details when you book: the difference between an integrated heating pump and a separate element changes the part, the price and whether the job is done in one visit.

What this page does not cover
This page covers the dual-badged range as a class and cannot tell you which platform your machine is — that is what the rating plate is for. Heater fitment, pump assemblies, filter types and connector layouts differ between the platforms this badge spans, and they belong on the family page where one exists. Machines badged AEG alone have their own page.
