Possible Causes
How to Fix / Troubleshooting
Safety first: Do not operate the dishwasher if you suspect electrical supply issues; consult an electrician if needed.
E27 indicates that the mains voltage is outside the acceptable range for the dishwasher.
- Step 1 – Check household supply:
- Verify that other appliances are working normally.
- If lights flicker or other devices malfunction, contact an electrician.
- Step 2 – Inspect terminal block:
- Disconnect power at the breaker.
- Access the connection box where the power cord enters the dishwasher.
- Check for loose or burnt connections; tighten screws if loose.
- Step 3 – Surge protection:
- Consider using a surge protector or having a voltage stabilizer installed if your area has unstable voltage.
If E27 persists despite stable mains voltage and good connections, the power module may be misreading voltage and require replacement.
