Before you order
- Compare the part number on the existing valve, or in the appliance documentation, against 0020031977 to confirm the match.
- Confirm the 8 kW rating is the one specified for the circuit being worked on.
- Check the connection arrangement and capillary or sensing bulb routing on the existing valve before removing it, so the new valve can be fitted the same way.
