I can provide general advice based on common practices.
The frequency of cleaning the sump filter in a dish machine depends on several factors, including the usage intensity, the type of dishes being washed, and the manufacturer's recommendations. In commercial settings such as restaurants and food establishments, dish machines are typically used frequently, leading to more rapid filter clogging.
Generally, it's recommended to clean the sump filter of a dish machine regularly to maintain optimal performance and prevent issues such as poor washing results, reduced water flow, and potential damage to the machine. A good rule of thumb is to clean the sump filter at least once a day for commercial settings with heavy usage.
For residential dishwashers, the frequency of sump filter cleaning may be less frequent, as they typically handle smaller loads and have less intense usage compared to commercial dish machines. In such cases, cleaning the sump filter once every few weeks or monthly may be sufficient.
However, it's essential to refer to the specific dishwasher's user manual or follow the manufacturer's guidelines for the recommended cleaning frequency. Manufacturers often provide maintenance instructions, including how to clean the sump filter properly and how often it should be done to ensure optimal performance and longevity of the appliance.
