The short answer
Check the program first, because many are cold by design. A true heating fault usually stretches the cycle far beyond its normal length as the machine waits for a temperature it cannot reach, and the cause is then the element or its sensor, both of which are service parts.
What you observe
- Door glass cold at every stage of a hot program — Consistent with no heating at all.
- Cycles running far longer than they used to — The machine waiting for a temperature it cannot reach.
- Results poorer across every program — A heating fault rather than a program choice.
- Only certain programs seem cold — Almost certainly by design; check the program temperatures.
- A breaker trip during the wash — Stop and read the electrical-safety page.
- Not this fault: laundry is clean but the machine smells — That is the odour page.
Ranked for domestic machines
- Program selected is cold or low-temperature by design — First, and it accounts for a large share of these reports.
- Heating element failed — Second, and the usual genuine cause.
- Temperature sensor drifted or failed — Third, and it typically produces long cycles rather than cold ones.
- Element scaled heavily in a hard-water area — Fourth: scale insulates the element and slows heating.
- Control not calling for heat — Fifth, and uncommon.
- Thermal protection opened after an earlier fault — Last, and it means something else happened first.
Check in this sequence
- Look up the temperature of the program actually being used — Free, and it resolves many of these complaints.
- Compare the cycle duration with what it used to be — A longer cycle is the signature of a real fault.
- Feel the door glass late in a hot wash, carefully — A rough but useful indication of whether heat is being produced.
- Run a hot program with a light load and time it — One controlled observation beats several vague ones.
What an owner can do
- Select a genuinely hot program and note the stated temperature — Many default programs are cooler than people assume.
About 10 min
- Time the full cycle and compare with its normal length — The clearest owner-side evidence of a heating fault.
About 120 min
- Touch the door glass carefully late in the wash — Warm glass means heat is being produced.
About 5 min
- Run a maintenance wash if the area has hard water — It addresses scale, which slows heating.
About 120 min
- Record which programs are affected — A fault affects all of them; a setting affects one.
About 10 min
- Stop before touching the element or its wiring — It is a mains-connected part inside a wet cabinet.
Hot water and mains wiring
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not force the door open during or straight after a hot wash; the water scalds and the lock is there for that reason. If a breaker trips during the heating phase, stop using the machine and treat it as an electrical fault.
When to call
Call when hot programs run long and finish cold, because that pattern points at the element or the sensor. Call urgently if the machine trips a breaker while heating, since that usually means a failed element rather than a cold wash. Ask what the repair costs before authorising it on an older machine: an element and a sensor are routine parts, but labour on a front loader is not trivial.

What is out of scope
Generalized across Electrolux washer families rather than for one model line; where a family-specific or model-specific page exists it carries the narrower answer. Not here: program temperature tables, element ratings, sensor values and descaling product recommendations.
