Unit operates but there is a high-pitched whistling noise from the tank area

Safety first: Unplug the unit before inspecting the tank and seals.

• 1. Check tank seating
  • Ensure the dirty water tank is fully inserted and latched.
• 2. Inspect gaskets
  • Examine the tank lid and base gaskets for cuts or flattening.
  • Replace gaskets if they no longer provide a tight seal.
• 3. Look for cracks
  • Inspect the tank body for hairline cracks that may leak air.
  • Replace the tank if damaged.
