You can pay attention to the following symptoms to understand that your water dispenser is dirty:
Water Taste and Smell: If the water has a different taste or smell than what you're normally used to, this could be a sign that your dispenser is dirty. Metallic, musty, or other abnormal tastes or odors may indicate contamination.
Visual Check: Check the inside and tap of the water dispenser regularly. If there is visible residue, rust, mold or discoloration on the inside or on the faucet, the dispenser may be dirty.
Water Flow: If there is a decrease or blockage in the flow of water flowing through the water dispenser, this may indicate that the pipes or filters inside the dispenser are dirty.
Water Tank Condition: If there is a slippery or sticky feeling on the inner surface of the water tank, this indicates the accumulation of microorganisms or other contaminants.
Duration of Use: If the dispenser has been used for a long time without being cleaned, lack of a regular cleaning routine may cause the dispenser to become dirty. Water dispensers should generally be cleaned every 3-6 months.
Water-Related Health Problems: If people who use the water dispenser frequently experience stomach upsets, diarrhea, or other water-related health problems, there is a high chance that your dispenser is dirty.
To prevent contamination of your water dispenser and maintain water quality, it is important to clean it regularly and check the filtration system periodically.
