Tea bar water dispenser is a modern automatic water supply equipment, which is widely used in small and medium-sized restaurants. However, due to long-term use or improper maintenance, there are some failures in drinking water opportunities. This paper will analyze the common faults of the tea bar water dispenser and provide corresponding maintenance methods.

1. Abnormal water quality or low flow: If this happens, first check the water source to ensure that there are no impurities in the water source or the water pressure is too low. If the water source is normal, you can disassemble the water dispenser, check whether the filter screen or smooth tube is blocked by foreign objects, and clean or replace the corresponding components.

Second, the water temperature is unstable or not hot: this kind of fault is usually caused by the burning of the heating pipe or the failure of the thermostat. After inspection, the corresponding parts can be replaced.

3. Abnormal noise or high temperature when the compressor is working: This situation is usually caused by insufficient oil in the compressor or wear of the compressor shaft and bearing. Solutions include adding proper lubricating oil or replacing a new compressor.

4. No drainage or abnormal drainage: Check whether the water pipe is blocked or leaking, and solve this problem by cleaning the pipe or replacing the corresponding parts.

It should be noted that for non-professionals, it is more common to carry out daily cleaning and maintenance of drinking fountains, such as replacing filter elements regularly. If you encounter problems that are difficult to solve, you'd better contact professional maintenance personnel to avoid irreparable losses.
