If a dishwasher is never used, several things could happen over time:
Dust and debris accumulation: If the dishwasher is not used or cleaned regularly, dust, dirt, and debris may accumulate inside the appliance, particularly in areas like filters and spray arms. This can affect the dishwasher's performance and may lead to clogs or blockages.
Odor and mold growth: Moisture can accumulate inside the dishwasher, especially in the areas where water tends to pool, such as the bottom and door seals. This can create a breeding ground for mold and bacteria, resulting in unpleasant odors and potential health hazards.
Deterioration of seals and gaskets: The rubber seals and gaskets in the dishwasher can dry out and deteriorate if the appliance remains unused for an extended period. This could lead to leaks when the dishwasher is eventually used.
Corrosion: If the dishwasher contains any metal components, they could be susceptible to corrosion over time, particularly if the dishwasher is located in a damp or humid environment.
Electrical issues: The electronic components of the dishwasher may also be affected if it remains unused for a long time. Dust and humidity can impact circuitry, potentially causing malfunctions.
Pest attraction: Food residue and moisture inside an unused dishwasher can attract pests like ants and cockroaches, leading to further hygiene and operational issues.
Reduced efficiency: An unused dishwasher may not function as effectively when eventually put into use. The accumulated debris, dried-out components, and potential mold growth could hinder its ability to clean dishes thoroughly.
To prevent these issues, it's a good idea to run the dishwasher occasionally, even if it's not used regularly. This helps keep the appliance functioning correctly and minimizes the risk of developing problems associated with prolonged inactivity. Additionally, cleaning the dishwasher and leaving the door slightly open when not in use can help reduce the chances of mold growth and bad odors.
