The short answer
Two things make this diagnosis different on a European machine. Later units of this platform heat water in the circulation path rather than with an element in the tub floor, so there is nothing visible to inspect and a restricted flow can shut the heater down. And drying here is by condensation with no heater at all, so a load that comes out clean but wet is not a heating fault.
What you are seeing
- Dishes are clean but stone cold at the end of the cycle — Note: A genuine heat problem. Start with the incoming supply temperature.
- Dishes are clean, hot and wet — Note: That is condensation drying working as designed. It is not a heating fault.
- Only plastics are wet — Note: Normal on this platform. Plastic holds too little heat to evaporate its own film.
- Greasy film survives on everything, including the tub — Note: The wash never reached a temperature that shifts fat, which is a heat symptom.
- The cycle takes far longer than it used to and finishes cold — Note: The machine is waiting on a temperature it cannot reach and eventually giving up.
- The breaker trips at the heat step — Note: Stop. That is earth leakage from the element and belongs on the electrical page.
Ranked causes on this brand
- Incoming water arriving cold, or a very long run from the water heater — Why this rank: First because many machines of this type are plumbed to a cold supply by design and heat everything themselves, so anything that lengthens that job shows up as a cold result on an already long program.
- Restricted flow shutting down a flow-through heater — Why this rank: Second because on later units of this platform the heater is in the circulation path rather than in the tub floor: it depends on water moving past it, and a blocked filter or a clogged spray arm makes it protect itself.
- A low-temperature or eco program selected — Why this rank: Third because it is not a fault, it is easily done by accident, and it produces exactly the complaint of a cold load.
- Sheathed sump element failed, on earlier units — Why this rank: Fourth: it is a real failure, but on this platform it more often announces itself by tripping a protection device than by quietly going cold.
- Temperature sensor reading high — Why this rank: Fifth because a sensor that reports the water as already hot stops the heat step early and produces a cold load with no other symptom at all.
- Circulation pump losing pressure — Why this rank: Last because it starves the heater in the same way a blocked filter does, but it also degrades cleaning at the same time, which distinguishes it.
What to check, in order
- Ask whether the load is cold, or merely wet — Why: Wet and hot is condensation drying and not a fault. Cold is a heating question. This separates two different complaints that arrive with the same words.
- Run a tap at the sink until it is hot and note how long it takes — Why: A long run from the water heater to the kitchen puts the machine at a disadvantage on every cycle.
- Check which program was selected and try the hottest one — Why: An eco program on a cold supply produces a much cooler result, by design.
- Twist out the filter and check the spray arm jets — Why: A flow-through heater shuts down when flow drops, so a restriction upstream reads as a heater fault.
- Feel the door and the tub interior at the end of the cycle — Why: A machine that has heated is warm to the hand inside; one that has not is not, and this is the simplest confirmation there is.
Checks you can do safely
- At the end of a normal cycle, open the door and put a hand on the inside of the tub wall. Note whether it is warm or cool. — Tools: none — Time: two minutes
- Run the kitchen hot tap until it runs hot and count how long that takes, then note whether the machine is plumbed to hot or cold. — Tools: none — Time: ten minutes
- Select the hottest or intensive program instead of eco and compare the result on the same kind of load. — Tools: none — Time: one cycle
- Switch off at the isolator, twist out the cylindrical filter, wash it under a hot tap with a soft brush and refit it with a full twist until it locks. — Tools: soft brush — Time: a quarter of an hour
- Clear every jet in both spray arms with a wooden cocktail stick and confirm each arm spins freely by hand. — Tools: wooden cocktail stick — Time: a quarter of an hour
- Top up the rinse aid and set its dosage a step higher, then judge drying separately from heating on the next cycle. — Tools: rinse aid — Time: five minutes
Before you open anything
Safety
Switch off at the isolator before reaching into the sump, and let the machine cool before opening it at the end of a cycle: water and steam in a dishwasher that has heated are hot enough to scald. If a protection device or breaker trips at the heat step, stop using the machine and treat it as an electrical fault rather than a heating one, because that pattern points at the element leaking to earth. Never cut or repair the inlet hose, which carries mains wiring in its sleeve to a solenoid at the tap end. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service
Where the service line falls
The filter is clean, the arms are clear, the hottest program is selected and the tub is still cool at the end of the cycle. The breaker or protection device trips at the heat step, which is an electrical fault and needs isolating rather than diagnosing at home. Cleaning and heating have both degraded together, which points at the circulation pump losing pressure rather than at the heater. The cycle now runs far longer than it used to and still finishes cold, which suggests the machine is waiting on a temperature it cannot reach. A heater has to be replaced, because on this platform it may be integrated with the circulation pump housing and is cross-referenced to a group-sibling part rather than ordered by badge.

What this page does not cover
This page is generalized across families and models on this European built-in platform, which used both a sheathed sump element and a flow-through heater across its generations. It prints no temperatures, because no measured figures for this brand exist in this reference. It does not cover a specific model family or fan-assisted drying variants. Identify your machine from the rating plate on the edge of the door or inside the tub rim rather than from the badge, because this manufacturer supplied the same platform under several group badges and a parts desk cross-references by platform, not by name.
