PulsaCoil 3 No Hot Water
The PulsaCoil 3, a widely used thermal store water heater, is known for its reliability. However, like any appliance, it can sometimes encounter issues, with “no hot water” being one of the most common. If you’re facing this problem, don’t worry—this guide will help you troubleshoot and potentially resolve the issue.
PulsaCoil 3 No Hot Water – Fix The PulsaCoil 3 Yourself
Several reasons could lead to a PulsaCoil 3 No Hot Water
Faulty Immersion Heater
- The immersion heater in the PulsaCoil 3 might be defective or burned out, preventing it from heating the water.
Thermostat Issues
- Malfunctioning thermostats can lead to inaccurate temperature readings or prevent the heater from activating when needed.
Limescale Buildup
- Over time, limescale can accumulate in the system, reducing the efficiency of the heat exchanger and affecting water heating.
Airlocks
- Airlocks within the system can block the flow of hot water, preventing it from reaching the taps or shower.
Faulty Pump
- A malfunctioning pump responsible for circulating water through the PulsaCoil 3 could hinder the distribution of hot water.
System Pressure
- Low system pressure can impede water circulation, resulting in insufficient heating.
Electrical Problems
- Issues with the PCB board, electrical supply or wiring can prevent the PulsaCoil 3 from functioning correctly.
Component Wear and Tear
- Components such as valves, sensors, or seals may degrade over time, leading to issues with the heating system.
Insufficient water
- Insufficient water in the thermal store can often result from either evaporation or leaks within the internal thermal cylinder or immersion heater. When the thermostat sensor malfunctions or a relay remains stuck open, it can lead to a condition known as “kettling,” causing the system to generate steam and thereby accelerate internal water evaporation within the cylinder. This ultimately leads to a shortage of hot water at the tap outlets. You can independently gauge your hot water levels by referring to our DIY video tutorial.
Failure of the external time clock
- This can prevent the ‘off-peak’ immersion from heating overnight, leaving the internal cylinder cold.
Step-by-Step Troubleshooting Guide
Check the Power Supply
- Verify that the unit is powered and that the circuit breaker or fuse is intact.
- If there’s no power, reset the breaker or replace the fuse.
Inspect the Thermostat
- Adjust the thermostat to ensure it’s set correctly.
- Use a multimeter to check for continuity and replace if faulty.
Examine the Pump
- Listen for operational noise or vibrations from the pump.
- If the pump isn’t working, it may need to be replaced.
Test the Heating Element
- Disconnect the unit from power and test the heating element for resistance.
- Replace the heating element if it’s damaged or non-functional.
Bleed the System
- Turn off the power and carefully bleed the system to remove airlocks.
- Turn the power back on and check if the hot water is restored.
Check and Replace Sensors
- Inspect the temperature and flow sensors for any visible damage.
- Use diagnostic tools to test sensor functionality and replace them if necessary.
When to Call a Professional
If you’ve followed these steps and your PulsaCoil 3 still isn’t producing hot water, it might be time to consult a professional. Complex issues such as internal wiring problems or advanced component failures are best handled by qualified engineers.
