A customer of ours had an appliance break down, and it's a simple PCB swap - anyone with at least an EST ticket can do it.
However, the manufacturer says that they don't sell spare parts to other contractors or to end users; you have to get their service tech to install them.
Consumer protection says that spare parts have to be 'available' - but does anyone know if this is a scenario covered by the CGA or other rules?
For what it's worth, this is a business device so they may have contracted out of the CGA and we're not rocking the boat, but it would be an interesting answer anyway.
