What it is
The electronic expansion valve, ETS 6-18, is a Vaillant component used to meter refrigerant flow through the refrigeration circuit. It is an electronically controlled valve, with the ETS 6-18 designation defining the variant fitted to the appliance family listed below. Its role is to regulate the flow of refrigerant entering the evaporator so the circuit operates at the correct condition for the demand on the system.
Signs this part needs replacing
- Reduced heating or hot water output from the heat pump
- Refrigerant circuit unable to hold the correct condition, with frosting or icing at the evaporator
- Compressor short cycling or cutting out under load
- Erratic or unstable refrigerant flow control during running
- Valve failing to respond to the control signal from the appliance
Before you order
- Confirm the appliance model is listed in the Fits section above
- Check the valve designation on the existing component matches ETS 6-18
- Confirm the manufacturer part number 0020210634 against the existing valve or the appliance documentation
- Work on the refrigerant circuit should be carried out by a competent heating engineer with the appropriate refrigerant handling qualifications
