Step 2: Empty and Clean the Water Tank
- Remove the water tank from the cleaner.
- Empty any remaining water and rinse the tank thoroughly with clean water.
- Check for cracks or damage to the tank that could cause leaks.
Ensure the tank is completely dry before reinserting it to prevent mold or moldy odors.
Step 3: Inspect and Clean the Filters
- Locate the filters—these are usually near the water tank or suction pathway.
- Remove the filters and rinse them under warm water.
- Allow filters to dry completely before reinstalling to maintain optimal suction.
If filters are damaged or excessively dirty, consider replacing them with compatible replacements, such as the JORAIR Brush Replacement for Bissell CrossWave (asin=B08ZS3PSD6).
Step 4: Check the Hoses and Valves for Clogs
Inspect all accessible hoses and valves for blockages or kinks. Use a long, flexible brush or pipe cleaner to gently clear any debris. Clogs restrict water flow and reduce suction, leading to water leakage or incomplete cleaning.
Step 5: Examine the Seal and Water Tank Connection
Ensure the water tank is seated properly and the seal is intact. A loose or damaged seal can cause water to leak during operation. Replace the seal if it appears cracked or worn.
Secure the water tank firmly in place before testing the machine again.
Step 6: Test the Cleaner and Replace Parts if Needed
Plug in the machine and run a short cleaning cycle on a small, inconspicuous area. Observe if water leaks or if suction improves. If issues persist, consider replacing worn brushes or internal components, such as the suction motor or brushes, with compatible parts like the JORAIR Brush Replacement.
