PulsaCoil A Class No Hot Water

PulsaCoil A Class No Hot Water – Fix The PulsaCoil A Class Yourself
PulsaCoil A Class No Hot Water? Common Issues
No Power to the Unit
- Check if the unit is receiving power. Ensure that the fuse box or circuit breaker has not tripped.
- Inspect the power switch on the unit itself. It should be in the “ON” position.
- Problems with the electrical supply, wiring or the complex PCB board can leave the PulsaCoil A-Class with no hot water and failing to function properly.
Sensor Issues
- The sensors control the temperature of the water. If they’re faulty, the water might not heat up correctly.
Airlock in the System
- Air trapped in the system can prevent water from circulating properly.
- Bleeding the system may help remove the airlock and restore hot water.
Faulty Heating Element
- A worn-out or malfunctioning heating element is a common cause of no hot water.
- Test the heating element with a multimeter and replace it if necessary.
Pump Failure
- The pump is responsible for circulating water. If it fails, you won’t get hot water.
- Listen for unusual noises or check if the pump is running. If not, it may need replacing.
System Pressure
- Low system pressure can impact the circulation of water through the system, leading to inadequate hot water heating.
Insufficient water in the thermal store
- Insufficient water in the thermal store can typically occur due to evaporation or leaks in either the internal thermal cylinder or immersion heater.
- If the thermostat sensor fails, or a relay remains stuck open, this can cause the system to steam or ‘kettle’, leading to internal water evaporation within the cylinder and ultimately resulting in a shortage of hot water at the tap outlets. You can assess your hot water levels independently by following our DIY video tutorial as a reference.
Failure of the external time clock
- This can prevent the ‘off-peak’ immersion from heating overnight, leaving the internal cylinder cold.
Troubleshooting Steps
Check Power Supply
- Ensure the unit is plugged in and the power switch is on.
- Verify that the circuit breaker has not tripped.
Reset the Unit
- Locate the reset button on your PulsaCoil A Class. Hold it down for 5-10 seconds to reset the system.
Inspect the Sensors
- Inspect the sensors and replace them if they’re damaged.
Test the Heating Element
- Use a multimeter to check for resistance of the heating element.
- Replace the element if it’s faulty.
Pump Failure
- The pump is responsible for circulating water. If it fails, you won’t get hot water.
- Listen for unusual noises or check if the pump is running. If not, it may need replacing.
