Possible Causes

Cracked solution tank, Worn tank bottom seal, Stuck-open tank outlet valve, Loose hose clamp at pump inlet

How to Fix / Troubleshooting

Safety: Unplug the Husqvarna carpet cleaner and remove all liquid from tanks before disassembly.

  • Inspect solution tank: Remove the tank, fill it over a sink, and check for cracks or leaks from seams. Replace the Husqvarna solution tank if it leaks when off the machine.
  • Check outlet valve and seal: Examine the bottom valve and O-ring. Clean and lubricate lightly with food-grade silicone grease. Replace worn seals.
  • Inspect internal hoses: Open the housing and check the hose from the tank seat to the pump. Tighten or replace hose clamps and any brittle hoses.
  • Store tank empty: To prevent future leaks, store the unit with the solution tank empty and removed.
