Possible Causes
Loose wiring harness between control board and motor, Failed main control PCB, Corroded connectors from moisture ingress, Shorted sensor line
How to Fix / Troubleshooting
Safety first: Unplug the cleaner and remove all tanks before opening the housing.
- Visual inspection: Remove the screws securing the main body panels and carefully open the housing. Look for any obvious signs of water damage, corrosion, or burnt components on the main control board.
- Check harness connections: Gently press all multi-pin connectors into the control board to ensure they are fully seated. Look for bent pins or green/white corrosion.
- Dry any moisture: If you see moisture inside, dry the area thoroughly with a lint-free cloth and allow the unit to air dry for several hours before reassembly.
- Reassemble and test: Refit the housing, plug in, and test. If E6 returns immediately, the main control board is likely defective and should be replaced.
Because this fault involves low-voltage electronics, if you are not comfortable working around PCBs and wiring, contact a qualified technician.
