Troubleshooting before booking a Service/Repair/Warranty job

POWER

1. Check the Power Source: Ensure your hot water unit is plugged into its own power point. Unplug it and test another appliance (like a phone charger or desk lamp) to confirm the power point is working.
2. Reset the Unit: Leave your hot water unit unplugged for a few minutes to clear any potential error lockouts.
   – Refer to Owner Manual for error codes and suggested solutions.
3. Contact an Electrician: If the power point isn’t working, reach out to an electrician for assistance.

GAS

1. Check Gas Valves: Ensure the gas valves to your meter and hot water unit are turned on.
   – Any other gas-related issues should be handled by a qualified gas plumber.

WATER

1. Minimum Flow Rate: Most hot water units require a minimum water flow of about 2.5 liters per minute to operate. If the
   flow is below this, the unit may not turn on.
2. Check the Inlet Strainer: A blocked strainer can restrict water flow. Follow this video for instructions on checking your strainer on your hot water unit.
   – Note: If your hot water unit is part of a gas-boosted solar hot water system, skip this step to avoid scalding risks. Only qualified technicians should check the strainer in such systems.
3. Inspect Fixtures: Blocked aerators or shower heads can significantly reduce water flow. If you notice that hot
   water is functioning at one fixture but running cold at another, this often indicates a blockage.
4. Testing for Blockages: Run Two Hot Water Taps simultaneously. If both fixtures start to run hot, it confirms a
   blockage in one of the fixtures.
   – Contact a Plumber: If a blockage is confirmed, reach out to a plumber to clean the affected fixtures.
5. Check for Cross Connections: Turn off the cold-water valve on the hot water unit (located on the middle pipe). If cold
   water runs from a hot tap when isolated, there’s a cross connection.
   – Contact a Plumber to investigate.

1. Check the Gas Connection: Inspect the hose and bayonet (connection point) fitting for kinks or damage that could block the gas supply.
2. Check Gas Valves: Ensure the gas valves to your meter and heating unit are turned on. Any other gas-related issues should be handled by a qualified gas plumber.
3. Clean Filters: Check and clean the unit’s filters, as they can accumulate dust and block airflow
4. Check Controls: Check user manual for a list of error codes and possible solutions.
5. Clean Filters: Check and clean the unit’s filters, as they can accumulate dust and block airflow.

1. Check the Power Source: Ensure your hot water unit is plugged into its own power point. Unplug it and test another appliance (like a phone charger or desk lamp) to confirm the power point is working.
2. Check the Thermostat: Ensure the thermostat is turned up. If not, turn up thermostate.
3. Check Timer: Has the timer been set to turn on at a specific time. If so, reset timer and see it this fixes the issue.

1. Check the Gas Connection: Inspect the hose and bayonet (connection point) fitting for kinks or damage that could block the gas supply.
2. Clean Filters: Check and clean the unit’s filters, as they can accumulate dust and block airflow.
3. Ensure Adequate Ventilation: Make sure the room is well-ventilated with a door or window open, as a faulty heater can produce carbon monoxide.

Air Conditioning

1. Check the Thermostat: Confirm the thermostat is set to the correct mode (“cool”) and temperature, and replace the batteries if it’s a battery-operated model. 
2. Check the Power Source: Verify the circuit breaker for your Air Conditoner unit hasn’t tripped; if it has, reset it. 
3. Check Air Filters: A dirty or clogged air filter restricts airflow, which can prevent your system from cooling effectively. Clean or replace it. 
4. Check Vents and Returns: Make sure furniture, curtains, or other items are not blocking the supply and return air vents. 
5. Check Error Codes / Checklists: Refer to Owner Manual for error codes if applicable and checklists for suggested solutions.
