What’s covered
Manufacturer remedy
Repair/replacement of accepted defective product; replacement retains the original remaining term without renewal. Jointly approved disputed testing is initially buyer-paid, with testing and transport reimbursed if the claim proves within warranty. Unconditional site labour/removal/reinstallation costs remain unestablished. The policy preserves Australian Consumer Law rights.
Labour
Unconditional full-term site labour coverage was not established and is not credited.
Freight
Conditional reimbursement of transport/testing expenses follows a valid jointly approved disputed test. This is not an unconditional full-term transport entitlement; outside-warranty costs are buyer-paid and original packaging requirements apply.
Removal and reinstallation
Unconditional removal and reinstallation coverage was not established and is not credited.
Exclusions
Labour: Unconditional full-term site labour coverage was not established and is not credited.
Freight: Conditional reimbursement of transport/testing expenses follows a valid jointly approved disputed test. This is not an unconditional full-term transport entitlement; outside-warranty costs are buyer-paid and original packaging requirements apply.
Removal and reinstallation: Unconditional removal and reinstallation coverage was not established and is not credited.
Transferability
An automatic transfer right was not established in the reviewed governing document.
How to make a claim
Start with the original installer or the manufacturer's Australian support channel. No mandatory initial app/web registration is established: unregistered owners use the supplied warranty card via email/dealer; registered owners use the app/web service route. Notify Dyness within 48 hours of discovering a defect; separate exclusion concerns failure not reported to seller/authorised service partner within two weeks. Provide purchase/serial/start-date/authorised defect evidence, logs and system/fault details. Without communications the term is three years; required link and outage tolerance remain unresolved.
