    Class I with a three core 0.75 mm flex, but definitely an all insulated plastic enclosure without any gaps.


    Thanks so for all purposes fails the earth bond test as un testable 




    Nope ... I disagree. "I can't" doesn't mean "It's no good".


    As I said earlier, to fail an appliance that has its exposed-conductive-parts shrouded to prevent a burn hazard is absolute nonsense. There are good reasons why many heating elements MUST be Class I, and that's to do with preventing overload and fire as much as electric shock ... and not impeding heat transfer at the same time.


    So, what's the answer ... well, again I said this earlier - this type of appliance has a plastic shroud over its exposed-conductive-parts, and someone who is competent to service and check that appliance will remove the cover and perform the test the way the manufacturer intended.


    The filter coffee machine I have at home has a similar issue - the only way to get to the element to perform the earth continuity test is to remove the bottom cover, which has tamper-proof screws. The heat plate is teflon and I can't get an earth probe to get a circuit from outside the appliance.


    Get it tested by someone who knows about that type of appliance.
