Here’s a list of tasks a technician might perform when addressing electrical issues in a geyser:

1. Initial Inspection:

• Check power supply: Ensure that the geyser is receiving proper voltage and there is no power supply issue (check fuse, circuit breaker, etc.).
• Examine the geyser's power cord and plug: Look for visible wear and tear, fraying, or damage.
• Inspect the switch or thermostat: Verify if the switch or thermostat is functioning correctly and not causing any electrical failure.

2. Turn Off Power:

• Switch off the geyser’s power supply at the main electrical panel to ensure safety before working on it.

3. Testing Electrical Components:

• Check the heating element: Use a multimeter to test the heating element for continuity. If it is damaged or faulty, it will need replacement.
• Test the thermostat: Ensure the thermostat is working properly and cycling the power to the heating element as required.
• Examine wiring connections: Check for loose, corroded, or damaged wires and connectors within the geyser.
• Test safety cutout: Many geysers have a thermal cutout for overheating protection, which must be inspected to see if it’s faulty.

4. Troubleshooting Issues:

• Faulty heating element: If the heating element is defective, the technician will replace it with a new one.
• Broken thermostat or faulty temperature control: Replace or recalibrate if necessary.
• Overloaded circuit or tripped breaker: Check the electrical panel to ensure the circuit breaker isn't tripped. If it is, the technician will assess the cause and fix it.

5. Replacement of Components:

• Replace damaged wiring: Any faulty wiring is replaced with the correct gauge wire for safety.
• Install new switch or thermostat: If the current switch or thermostat isn’t working properly, a replacement is fitted.

6. Reassemble and Test:

• Reassemble the geyser: Once repairs are made, the technician will put the geyser back together, ensuring everything is tightened and secured.
• Test the system: Turn the power back on and test the geyser to ensure it is heating water correctly and no electrical issues remain.
• Check for any leaks: Ensure no electrical or water leaks are present around the geyser’s electrical connections.

7. Final Safety Checks:

• Grounding check: Ensure proper grounding of the geyser to prevent electrical hazards.
• Check earth leakage protection: Make sure the geyser is properly integrated with an earth leakage circuit breaker (ELCB) for safety.

8. Customer Instructions:

• Provide the customer with basic maintenance tips to avoid future issues.
• Explain any repairs made and ensure they understand how to use the geyser safely.

The technician will document all work completed and ensure the geyser is safe to use before leaving the site.
