Water pumping system and method of troubleshooting the same

A water pumping system comprising:

• a heater;
• a temperature sensor configured to detect a temperature of the heater;
• a water pump configured to pump water through the heater;
• and
• a controller electrically connected to the heater, the temperature sensor and the water pump, the controller being configured to control heating up of the heater,
• when the temperature detected by the temperature sensor has reached a pre-determined operating temperature, control the water pump to pump water through the heater with a default water pumping power,
• determine whether the temperature of the heater after the water pump has started operating for a first pre-determined period is less than or equal to a pre-determined overheating temperature,
• when it is determined that the temperature of the heater after the water pump has started operating for the first pre-determined period is less than or equal to the pre-determined overheating temperature, control the water pump to continue pumping water with the default water pumping power, and
• when it is determined that the temperature of the heater after the water pump has started operating for the first pre-determined period is greater than the pre-determined overheating temperature, control the water pump to pump water through the heater with an alternative water pumping power that is greater than the default water pumping power.
