The short answer
Cold or lukewarm wash water on a Contoure washer usually means the hot supply never arrived, not that a heating element failed, because many compact and combination units in this class take hot water from the coach water heater rather than heating it internally. Start at the water heater and the mixing valve. On a combination model, a failure to dry is a separate matter and belongs to the condensing circuit.
What you are actually seeing
- The wash water is cold on every cycle including the hottest setting — Means: on-page
- Hot water reaches the galley tap but the washer still washes cold — Means: on-page
- The machine washes warm but never hot — Means: on-page
- On a combination model, laundry comes out of the dry phase still damp — Means: on-page
- Heating worked before a trip and not after — Means: on-page
- The cycle stops early with the drum still full — Means: different-fault — Go to: contoure-washer-problems
- A hot or scorched smell during the dry phase — Means: different-fault — Go to: contoure-washer-electrical-safety
- Body: The wash water is cold on every cycle including the hottest setting. Hot water reaches the galley tap but the washer still washes cold. The machine washes warm but never hot. On a combination model, laundry comes out of the dry phase still damp. Heating worked before a trip and not after. Some near-miss symptoms belong on a different page: The cycle stops early with the drum still full points at a cycle or drain fault rather than a heating fault, covered on contoure-washer-problems; A hot or scorched smell during the dry phase points at a fault that should be treated as an electrical hazard, covered on contoure-washer-electrical-safety.
Causes, ranked for this machine
- The coach water heater is off, in the wrong mode, or has not recovered — Why this rank: This ranks first because on this class of machine the hot water is supplied, not generated, which inverts the ranking that a household washer page would use
- The hot supply valve behind the machine is closed or only part open — Why this rank: Isolation valves are routinely closed for travel or winterising and forgotten
- The machine is set to a cold or eco cycle, or a cold-fill option is enabled — Why this rank: Compact machines default to cold on more cycles than owners expect
- A blocked inlet screen on the hot side restricting flow — Why this rank: Coach water systems carry more sediment than a municipal household supply, and the screen is the first thing it reaches
- A failed inlet valve, thermistor or heating element where one is fitted — Why this rank: Last, because it is the only part-replacement cause and the four above it are free to check
- Body: Most likely: The coach water heater is off, in the wrong mode, or has not recovered. This ranks first because on this class of machine the hot water is supplied, not generated, which inverts the ranking that a household washer page would use. Next most likely: The hot supply valve behind the machine is closed or only part open. Isolation valves are routinely closed for travel or winterising and forgotten. Third: The machine is set to a cold or eco cycle, or a cold-fill option is enabled. Compact machines default to cold on more cycles than owners expect. Fourth: A blocked inlet screen on the hot side restricting flow. Coach water systems carry more sediment than a municipal household supply, and the screen is the first thing it reaches. Fifth: A failed inlet valve, thermistor or heating element where one is fitted. Last, because it is the only part-replacement cause and the four above it are free to check.
What to check, in order
- Run the galley hot tap until it is genuinely hot, to prove the water heater has recovered
- Open the hot isolation valve behind the machine fully and confirm the hose is on the hot port
- Select the hottest wash the machine offers with every eco or cold-fill option turned off
- Close both valves, unplug the machine and inspect the hot inlet screen for sediment
- Body: First, run the galley hot tap until it is genuinely hot, to prove the water heater has recovered. Second, open the hot isolation valve behind the machine fully and confirm the hose is on the hot port. Third, select the hottest wash the machine offers with every eco or cold-fill option turned off. Fourth, close both valves, unplug the machine and inspect the hot inlet screen for sediment.
Checks you can safely make yourself
- Run the nearest hot tap until the water is hot to the hand, so that the washer is not simply drawing the cold slug in the line — Tools: none — Time estimate: a few minutes
- Trace both supply hoses behind the machine and open the hot valve fully, checking that the hot hose is on the hot inlet — Tools: torch — Time estimate: a quarter of an hour
- Select the hottest available cycle, switch off any eco, cold-fill or quick option, and start the machine — Tools: none — Time estimate: a few minutes
- Switch off the machine and close both valves, unscrew the hot inlet hose and lift out the small screen, rinse it and refit it — Tools: pliers, small brush, towel — Time estimate: a quarter of an hour
- Start a hot cycle and feel the hot inlet hose during the fill: it should warm within the first part of the fill — Tools: none — Time estimate: a few minutes
- Body: Step one: Run the nearest hot tap until the water is hot to the hand, so that the washer is not simply drawing the cold slug in the line. Tools: none. Time: a few minutes. Step two: Trace both supply hoses behind the machine and open the hot valve fully, checking that the hot hose is on the hot inlet. Tools: torch. Time: a quarter of an hour. Step three: Select the hottest available cycle, switch off any eco, cold-fill or quick option, and start the machine. Tools: none. Time: a few minutes. Step four: Switch off the machine and close both valves, unscrew the hot inlet hose and lift out the small screen, rinse it and refit it. Tools: pliers, small brush, towel. Time: a quarter of an hour. Step five: Start a hot cycle and feel the hot inlet hose during the fill: it should warm within the first part of the fill. Tools: none. Time: a few minutes.
Safety first
Safety
Close the water valves and unplug the machine before removing an inlet hose, and be ready for the water still standing in the hose. Never remove an appliance panel to reach a heating element with the machine plugged in. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
Call a technician when the coach hot water is proven hot at a nearby tap, the hot valve is open, the inlet screen is clean, the hottest cycle is selected with no eco options, and the wash is still cold. That leaves the inlet valve, the thermistor or the element, all of which sit behind a panel with mains terminals.
