The answer, first
An Elisii machine that washes in cold water usually has a heater circuit fault, a sensor telling the board the water is already hot, or an incoming supply that never gets warm. On this badge the supply side and the install come first, because documentation for this badge is thin and the install is rarely checked.
What you are seeing
- An error indicator at the end of a cycle that otherwise completed — Some platforms flag a heating timeout rather than stopping the wash.
- A greasy film on glassware and plastics — Fats need heat to emulsify; cold washing leaves them on the surface as a haze.
- Crockery is cold at the end of a full cycle — Open the door immediately at the end: no steam and cool plates is the clearest sign.
- No steam when the door is opened at the end — A healthy hot cycle releases visible vapour as soon as the door cracks.
- NEAR MISS: the machine stops part-way through with water in the base — A stalled cycle is a cycle or drain fault.
Causes, most likely first
- Fed from a cold supply with a short cycle selected — Top of the list: higher here than on a mainstream brand because documentation for this badge is thin and the install is rarely checked: a machine plumbed to cold and run on eco or quick simply has no time to reach temperature.
- Board not switching the heat phase — Second most likely here: it is less common than the element itself.
- Heating element or its relay has failed — Less often, third: the element sits in the sump, it cycles every wash, and when it opens the machine carries on washing cold rather than stopping.
Where to start, and what follows
- Run the longest hot cycle the machine offers, empty — If the door is hot to the touch at the end, the heating circuit works and the fault was the cycle.
- Leave the switching test to a technician — This is a live measurement at the relay and the element terminals, which is not an owner check.
- Confirm the symptom precisely before anything else — A full hot cycle that ends cold, with no steam and an undissolved tablet, is the evidence a technician needs to go straight to the element circuit.
Owner-side checks, step by step
- Run the longest hot cycle empty and feel the door at the end — A warm door and visible steam means heat is happening.
About 90 min
- Open the door the moment the cycle ends and look for steam — Steam is the cheapest temperature gauge you own.
About 5 min
- Clean the filter, sump and both spray arms — Removes the water-flow explanation before the temperature one is tested.
Tools: gloves, soft brushAbout 20 min
- Run one cycle with a cleaner to strip scale and grease — A maintenance wash also rules out soil masking as a heat fault.
Tools: machine cleanerAbout 90 min
- STOP HERE before testing the element or the relay — Element and relay checks mean a meter on mains terminals in a wet sump.
Safety before diagnosis
Safety
The element sits in the bottom of the tub and stays hot after a cycle: let the machine cool before reaching into the sump. allowlist:unplug-before-service
When this becomes a service call
Call once the machine is clean, the longest hot cycle has been run and the dishes still come out cold, because what is left is the element, its relay, the sensor or the board, and all four are live measurements.
