Amana offers factory-certified replacement filter parts through its website. Dishwasher assemblies include multiple parts, making identification of the specific part that requires replacement necessary. Knowing the model number of the dishwasher can be useful when requesting assistance in purchasing the replacement.
Dishwasher filter assemblies are designed to be either self-cleaning or removed and cleaned rather than replaced on a regular basis. Replacement is necessary only when a part becomes damaged or significantly worn. Filters designed to be cleaned manually are designed for easy access and removal, while self-cleaning filters require a portion of the dishwasher to be disassembled to inspect or replace the filter parts.
