What to do if my Nilfisk-Advance MH 1C is not drawing detergent?
- JJeffrey HallAug 10, 2025
If your Nilfisk-Advance Pressure Washer isn't drawing detergent, first, top up the detergent tank. If that doesn't work, clean the detergent tank. As a final step, remove the suction valve and either clean or replace it.
