How to Fix / Troubleshooting
Safety first: Disconnect from mains immediately if you smell burning or see smoke. Do not continue to operate the appliance.
- Visual inspection: Remove the top cover and locate the main control PCB (usually in a plastic housing). Look for burn marks, melted plastic, or bulging components.
- Check connectors: Ensure all multi-pin connectors are fully seated and not heat-damaged. Pay attention to the main power input and motor/heater outputs.
- Check for external causes: Inspect the motor and heater wiring for shorts to the chassis or signs of overheating that could have damaged the PCB.
- Reset attempt: With everything reconnected, leave the machine unplugged for 10–15 minutes, then reconnect and try a short cycle. If E08 reappears immediately, the PCB is likely faulty.
- Replacement: Replacing the main control PCB requires matching the exact Bush model and sometimes programming. This is typically a level-5 repair; consider using an authorised service centre.
