Experiencing a water dispenser overheating issue? Discover the reasons behind it and how to fix it in this comprehensive guide!
1. Understanding the Operating Principles of Water Dispensers
Water dispensers are essential appliances used for heating water to provide hot water for daily activities. Learn how they work and ensure efficient performance.
When using hot water, the pressure in the pipes pushes it out, while cold water continues to flow into the dispenser. The heating mechanism remains active to maintain a constant supply of hot water.
2. Identifying Causes and Resolving Overheating Issues in Water Dispensers
Incorrect Temperature Settings
Incorrect temperature settings can result in the water heater becoming too hot due to excessively high water temperatures. To remedy this situation, adjust the water temperature to a safe range of 49 - 54 degrees Celsius. This adjustment will also help reduce the risk of scalding and improve energy efficiency.
Faulty Temperature Control Knob
Excessive heating in the water heater can also occur if the temperature control knob is malfunctioning. In such cases, users are unable to adjust the temperature to their desired level, leading to excessively high water temperatures. Solution: Replace the faulty temperature control knob. Contact the warranty center or a professional repair technician for assistance.
Water Heater Overheating Issue
Another potential cause of the water heater overheating is a malfunctioning temperature control knob. When this happens, users cannot adjust the temperature to their desired level, resulting in excessively high water temperatures. Solution: Replace the defective temperature control knob. Reach out to the warranty center or a professional repair technician for help.
When pressure reducing valve encounters a malfunction.
The pressure reducing valve is a component that helps the hot and cold tank adjust pressure. When the pressure reducing valve cannot function due to damage, it will cause the water pressure in the tank to increase, and the hot and cold tank becomes too hot.
Effectively troubleshoot this case by removing the valve for inspection. If the pressure reducing valve is damaged, you need to replace it or contact the warranty center for repair.
Low water pressure.
Another cause of the hot and cold tank becoming too hot is due to excessively low water pressure. Therefore, the heating element will not operate in time, causing the discharged water to be too hot.
Solution: In the case of detecting excessively low water pressure, adjust the water supply by placing the hot and cold tank in a higher position so that the water source is pumped continuously and maintained stable.
When the circuit board of the hot and cold tank is damaged.
The circuit board of the hot and cold tank serves as the central control for machine operations. If the circuit board is damaged, the tank will not operate normally and may result in excessively hot water.
For this reason, do not attempt to disassemble the hot and cold tank for inspection. Instead, contact the warranty center or repair technician for assistance.
ELCB device of the hot and cold tank malfunctions.
In addition to the aforementioned causes, the hot and cold tank overheating issue may also occur due to the malfunction of the ELCB device. Normally, the ELCB - a safety protection device, will automatically disconnect to ensure safety if any danger is detected. However, when the water is too hot, it causes this component to malfunction and results in excessively hot water discharge.
If you inspect and find the ELCB is damaged, immediately disconnect the power to the hot and cold tank and contact the warranty center or technician for inspection and repair to ensure safety.
It can be observed that the issue of the hot and cold tank overheating occurs due to various reasons such as a malfunctioning ELCB component, weak water pressure, or even a damaged temperature control button... We hope this article from Mytour has provided useful information to help you identify the cause and effectively resolve the issue. Thank you for reading!
