E6 error displayed; unit may power on but no ice is produced; water pump and fan may still run.

Safety: Unplug the ice maker before accessing the compressor compartment. Capacitors and wiring can carry dangerous voltage.

Diagnostic steps:

• 1. Listen for compressor: When starting a cycle, listen for a low humming or clicking from the compressor area. Repeated clicking without running suggests a start issue.
• 2. Access compressor components: Remove the rear panel to expose the compressor, start relay (PTC), and overload protector.
• 3. Inspect the PTC relay: Disconnect the relay from the compressor terminals. Shake it gently; if it rattles or smells burnt, it is likely defective.
• 4. Check wiring: Ensure all spade connectors are tight on the compressor terminals and relay. Look for heat damage.
• 5. Replace PTC relay: Install a new Vremi compressor PTC start relay matched to your model. Reconnect the overload and wiring as originally configured.
• 6. Test operation: Reassemble, plug in, and start a cycle. If the compressor still fails to start and E6 returns, the compressor windings or control board may be faulty.

Warning: Testing compressor windings and sealed-system work should be done by a qualified technician. Do not attempt to open the sealed refrigeration system yourself.
