Possible Causes
Burnt-out integrated heater in circulation pump, Internal thermal fuse open, Wiring fault to heater terminals, Control board heater relay failure
How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and close the water tap. Heating components are live at mains voltage.
- Confirm no heating: Run an intensive program and open the door carefully after 20–30 minutes. If the water is still cold and E09 appears, the heater is not working.
- Visual inspection: Remove the side panel and bottom cover to access the circulation pump with integrated heater. Check for burnt connectors or melted plastic around the heater terminals.
- Advanced electrical check: With the appliance unplugged, measure resistance across the heater terminals. An open circuit indicates a failed heater.
- Replacement: On many Balay models, the heater is integrated with the circulation pump and must be replaced as a complete unit. This is a complex repair involving hose clamps and seals; if you are not experienced, contact a professional.
