Ohme charger shows E08; app may indicate 'PEN fault' or 'Earth monitoring fault' and charging is disabled.

Critical safety warning: A PEN fault can make exposed metalwork live. Do not attempt to bypass PEN protection. Stop using the charger until the issue is resolved.

• 1. Isolate the charger: Turn off the charger at the consumer unit/isolator and do not turn it back on until checks are completed.
• 2. Check for other symptoms: If lights are flickering or other appliances behave erratically, contact your electricity supplier immediately as there may be a network neutral fault.
• 3. Verify earthing (electrician only): A qualified electrician should confirm that the earthing arrangement matches the Ohme installation requirements and that all neutral and earth connections are tight and correctly terminated.
• 4. Internal PEN module check: If the supply is confirmed healthy, a technician can test the internal PEN fault detection module and associated wiring. A faulty module or main PCB may need replacement.
• 5. Do not defeat safety: Never link neutral to earth or modify the PEN detection wiring to clear the error. This is dangerous and non-compliant.
