What it is
The Vaillant 0020247021 is a connection cable for the VR10 DHW sensor. It links the cylinder or DHW sensor to the appliance's control electronics on Vaillant EcoTEC Plus, Ecofit Pure and Ecofit Sustain models. It is supplied as a single cable assembly for sensor wiring.
Signs this part needs replacing
- DHW temperature reading is missing, erratic or clearly incorrect at the appliance
- Fault code relating to the DHW sensor or cylinder sensor circuit
- Sensor resistance tests correctly at the sensor but the appliance still fails to read it
- Visible damage to the cable, such as a split sheath, crushed section or exposed conductor
- Intermittent DHW faults that change when the cable or its connectors are moved
Before you order
- Confirm the appliance model and variant against the fit list above
- Check the existing cable routing and connector type at both the sensor and the appliance end
- Verify the fault is in the cable rather than the sensor itself before ordering
- Have the appliance's model and serial details to hand when checking compatibility
