Which cycle is actually selected?
Most compact apartment washers heat their own water rather than drawing a hot supply, so a cold wash here really can be a heating fault - but a cool cycle selected by habit is far more common. Establish which cycle is being used before anything else.
What you are seeing
- Every cycle washes cold whatever is selected.
- Warm cycles are only lukewarm.
- Greasy soil is no longer removed.
- The cycle time has become much longer.
- The cycle time has become much shorter.
- Not this fault: A cycle that stalls partway is a cycle fault - read that page.
- Not this fault: Residue on clothes with warm water is a detergent problem.
Most likely causes, in Direct Supply order
- A cool or eco cycle selected by habit — Why ranked: First on any machine used daily. It is not a fault, and it explains most cold-wash complaints.
- Cold-only supply connected at installation — Why ranked: Second: where a machine can take a hot feed and only the cold was connected, it must heat everything itself and long cycles follow.
- Heating element or its relay failed — Why ranked: Third. The machine fills correctly and never warms, and the cycle usually runs longer as it keeps trying.
- Temperature sensor reading high — Why ranked: Fourth, which stops the machine calling for heat and typically shortens the cycle instead.
- Inlet screen blocked, throttling the fill — Why ranked: Last, which gives a slow fill and a weak wash across every cycle.
What to check, in order
- Check which cycle is being selected, and try a warm one deliberately. — Because: A cool default is the leading cause and it costs nothing to exclude.
- Note whether the cycle has become longer or shorter. — Because: Longer means the machine is trying and failing to heat; shorter means it thinks it is already hot.
- Feel the door glass partway through a warm cycle. — Because: Warm glass means the heater is working, which redirects the whole diagnosis.
- Check whether a hot supply is connected at all. — Because: A cold-only connection on a machine designed for both explains long cycles and lukewarm results.
Checks you can do safely
- Select a deliberately warm cycle and run a normal load. — N: 1 — Tools: None — Time: one cycle
- Feel the door glass partway through that cycle. — N: 2 — Tools: None — Time: one cycle
- Note the cycle duration and compare it with what the machine used to take. — N: 3 — Tools: Timer — Time: one cycle
- Check behind the machine for which supply hoses are connected. — N: 4 — Tools: Torch — Time: moderate
- Report a machine that stays cold on a warm cycle. — N: 5 — Tools: None — Time: quick
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. Do not open the door mid-cycle on a hot wash, and never adjust a building hot water setting to compensate for a machine. Report a machine that trips its breaker at the heating stage rather than resetting it. Never run a machine with a panel removed. Let the drum cool before reaching in after a hot cycle.
When this becomes a service call
The machine stays cold on a deliberately warm cycle. The cycle time has changed sharply with no change in use. The machine trips its breaker at the heating stage. There is a smell of scorched plastic during a wash.

What this page does not cover
This page covers the in-room compact washers supplied under the Direct Supply name into resident apartments. It does not cover the contract washers in shared laundry rooms, many of which take building hot water instead of heating it, and it names no model-specific element or temperature. Where a family- or model-specific page exists it supersedes this one.
