To fix a Frigidaire dishwasher that doesn't empty completely using a cleaner, follow these steps:
Start by running a cleaning cycle using a dishwasher cleaner specifically designed to remove buildup and residue.
Follow the instructions on the cleaner's packaging for the appropriate amount and the specific cleaning cycle to select on your dishwasher.
Ensure that the dishwasher is empty before running the cleaning cycle to allow the cleaner to work effectively.
Once the cleaning cycle is complete, inspect the dishwasher's drain filter and drain hose for any clogs or debris.
Clean or unclog the filter and hose as necessary to ensure proper drainage. Refer to the dishwasher's user manual for specific instructions on how to access and clean these components.
If the issue persists after attempting these steps, it is recommended to contact Frigidaire customer support or schedule a service appointment with a qualified technician for further assistance.
