Warranty & RMA
Clear commitments instead of fine print: what is covered, how fast we respond and how a warranty case actually works.
Your coverage at a glance
- 12 months statutory warranty from delivery (B2B, per our Terms & Conditions).
- Manufacturer warranty on top – duration depends on brand and model; we handle or support the process for you.
- DOA protection: dead on arrival? Report within 7 days – prioritised handling with replacement or repair.
- Support in English and German, replies within 24 hours on business days.
DOA – dead on arrival
The unit does not start or hashes clearly below specification? Report it within 7 days of delivery with the serial number, photos or a short video and a description to ks@jewomining.com. DOA cases get top priority – the goal is a fast replacement or repair, without lengthy discussions.
How a warranty case works (RMA)
- Report with serial number, invoice number, fault description and photos or logs.
- Remote diagnosis by our technicians – firmware, network or PSU issues are often solved without sending anything in.
- RMA approval with shipping instructions if a return is required.
- Inspection and repair or replacement.
- Return shipment – with status updates at every step.
What the warranty does not cover
- Damage from overvoltage, unstable power supply or incorrect voltage
- Operation outside manufacturer specifications (cooling, temperature, dust, humidity)
- Unauthorised firmware, overclocking or hardware modifications
- Transport damage after risk transfer on self-arranged transport
- Cosmetic wear and wear parts (e.g. fans) unless there is a material or manufacturing defect
