Possible causes of no hot water in a SIMPA NS11RM include:
1. Fault code not cleared – Try closing and reopening the hot water tap. If it doesn't clear, turn off the power supply, wait 10 seconds, and restart the water heater. 2. Power supply is off – Ensure the power supply and ON/OFF button are turned on. 3. Water inlet valve or gas valve is closed – Confirm both are open. 4. Minimum water pressure not met – Ensure water pressure is at least 10 kPa. 5. Hot water volume is below 2.4 L/min – Flow may be too low to activate heating. 6. Faulty components – Issues with sensors, flame rod, or protection devices may prevent operation.
If the issue persists, contact Towngas Customer Service Hotline.
