If you encounter issues with your Blissthrill Cordless Pressure Washer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow or weak pressure | Air in the system (not primed) Clogged filter head Low water supply Improper hose connection | Prime the pump by pouring water into the inlet. Clean the weighted filter head. Ensure adequate water supply. Check all hose connections for tightness. |
| Unit does not turn on | Battery not charged Battery not properly installed | Charge the battery fully. Ensure the battery is securely clicked into place. |
| Water leaks from connections | Loose connections Missing O-rings or seals | Tighten all connections. Check for and replace any damaged or missing O-rings/seals. |
