The short answer
On a Crossover washer, a cold wash comes down to which tap is connected, which programme is selected, and whether the machine has a heater in the first place. Context for the ranking below: this page is written for a portable, plumb-to-the-tap washer rather than a fixed installation.
What the owner observes
- The hot tap runs hot at the sink but the wash is cold — The hot inlet or its screen rather than the household supply.
- Only some programmes wash cold — Normal on eco and delicate cycles, which use less heat deliberately.
- Washing is coming out greasy or dull — The usual practical consequence of washing cool.
- The machine takes far longer than it used to — On a machine that heats internally, a control waiting for a temperature.
- NEAR MISS — clothes come out soaking wet — That is a spin or drainage problem, not a heating one.
Causes, most likely first on this line
- Cold or eco programme selected — Many machines also have a cold-only option that is easy to leave engaged. Ranked first here because the design trades plumbing permanence for portability, which puts the hose, coupler and drain path at the top of almost every fault list.
- Hot supply not connected or turned off — Machines with two inlets take hot from the tap, and a hot hose left disconnected or a tap left closed gives a permanently cold wash. Second, because the machine is wheeled to the sink and coupled up for every wash, so the connection points take more handling in a month than a plumbed machine takes in a year.
- Long or cold supply run — A machine at the far end of a run receives a slug of cold water on every fill, and a short cycle never recovers from it.
- Hot inlet screen blocked — It shows as a slow hot fill that the machine tops up with cold.
- Heating element failed, where one is fitted — The consequence is a machine that runs its full cycle and never warms.
The order of checks
- Select a hot programme deliberately and feel the door glass partway through — First — It rules out the only cause that needs no repair whatsoever.
- Check which taps are connected and open, and what the tap itself is set to — Second — It is the most common cause on this class and it is settled in a moment.
- Time how long the nearest hot tap takes to run hot — Third — It tells you what temperature the machine is actually being offered.
- Turn off the tap, disconnect the hot hose and look at the screen in the valve — Fourth — A visibly silted screen explains a cold wash with the hot supply correctly connected.
Steps you can take yourself
- Check which taps are connected and fully open — On a two-inlet machine, confirm the hot hose is on the hot tap.
About 10 min
- Clean the inlet screens — Turn the taps off, disconnect each hose and rinse the screen in the valve.
Tools: pliers, clothAbout 25 min
- STOP before removing a panel to test an element — The element sits in the sump on live terminals.
Safety first
Safety
Unplug the washer and close the taps before disconnecting a hose or removing any panel; a capacitor can hold a charge after the power is off. Water left in a machine after a hot programme can scald, so let it stand before opening a filter or a hose. allowlist:unplug-before-service
Where the owner fix ends
Call when the hot supply is proven, the screens are clean, a hot programme has been selected and the drum is still cold midway through. On a machine that heats internally, that points at the element or the control that drives it, both of which need a meter. One installation detail shifts the odds on this line: these washers are used at a kitchen or bathroom tap, often on tile or vinyl, and are re-sited frequently.

Generalized information — what is not here
This page covers the Crossover washer as a class rather than one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and is linked below. Not covered here: element ratings, valve part numbers and the sump teardown, which differ by model line.
