90kw electric water heaterMaintenance process

Regular cleaning: Regular cleaning is an important step in maintaining normal operation. Firstly, turn off the power and wait for the device to cool down. Then, use a soft cloth to wipe the surface of the heater and the inside of the water tank to ensure that there is no accumulation of dust or debris. In addition, clean the filter screens at the inlet and outlet to prevent blockage.

Checking the circuit: Regularly checking the circuit is the key to ensuring the normal operation of the electric water heater. Check whether the wires and plugs are worn or aged. If any damage is found, they should be replaced in a timely manner. In addition, check whether the power wiring is secure and whether the connection between the controller and the sensor is good.

Check safety devices: Regularly inspect safety devices to ensure the safety of equipment operation. Check if the over temperature protection device, leakage protection device, and pressure safety valve are working properly. If any abnormal situation is found, it should be replaced or repaired in a timely manner.

Checking water quality: Regularly checking water quality is the key to ensuring the long-term operation of electric water heaters. Determine whether the water contains excessive salt or impurities through water quality testing. If the water quality does not meet the requirements, water treatment should be carried out in a timely manner to prevent scale or corrosion from damaging the equipment.

Lubricating components: According to the instructions in the user manual, regularly maintain the lubricating components. For example, adding oil or replacing lubricating oil to motor bearings and pump bearings to ensure their normal operation.

90kw electric water heaterFault diagnosis: When a fault occurs, the first step is to perform fault diagnosis and identify the cause of the fault. Fault diagnosis can be carried out by observing the operating status of the equipment, checking sensor data, and using fault diagnosis tools.

Repair circuit: If a problem is found in the circuit that causes the equipment to malfunction, circuit repair is required. According to the circuit diagram and user manual, inspect components such as wires, plugs, and connectors, identify damaged or loose areas, and repair or replace them.

Component replacement: When a component is damaged, it needs to be replaced in a timely manner. According to the device model and specifications, purchase the corresponding components and replace them according to the user manual or manufacturer's instructions.

Repair heating element: Heating element is an important component. If the heating element malfunctions, it may cause the equipment to not heat water properly. To repair the heating element, it is necessary to first disconnect the power supply, then disassemble the heating tube, check for damage or blockage, and clean or replace it.

Water tank repair: If leakage or rust is found in the water tank, it is necessary to repair the water tank. Firstly, drain the water tank, then inspect the leak, identify the cause, and seal or replace damaged components.
