Why does my Jon-Don PE500 have no vacuum?
- JJennifer WadeAug 16, 2025
If your Jon-Don Carpet extractor has no vacuum or weak vacuum, here are several potential causes and solutions: * The vacuum tank might be full; if so, empty the tank. * The float assembly tank screen could be dirty; clean the screen with water. * The float ball may be stuck; tap the float to unstick it, then clean it. * The vacuum hose might be damaged or loose; attach or replace it. * The dump valve could be open; close the valve. * The access lid might not be sealed; replace the gasket. * The vacuum hose might be clogged; clear any debris. * The air intake grid could be clogged; clean it. * There might be a leak in the recovery tank; clean and dry the area, then patch it with silicone. * Water might be coming out of the vacuum exhaust; use a low-foaming detergent.
