The Mk6 generation of GHD has just one model - the GHD Eclipse. For more details see our GHD Eclipse page.
This model is significantly harder to repair than previous GHD models as the internals are all integrated into one big custom circuit board (rather than separate circuit board, heaters, thermal fuse etc like previous models). Therefore this model is not covered by our repair service. The only repair that is really viable to DIY is a cable replacement, however it is tricky to do. There is a guide to dismantling the mk6 irons here. Cables are available below.
If you are unsure which model you have, please see our GHD models page which shows you pictures of all the different models.
