    Why is there only a small amount of solution reaching the brush on my KENT Floor Machine, or no solution at all?

      There might be several reasons why the KENT Floor Machine isn't dispensing enough solution: * The solution filter could be clogged or dirty, requiring cleaning. * The solution tap might be stuck closed, necessitating replacement. * The solenoid valve may be broken, or the electrical connection could be faulty, in which case you should replace the solenoid valve or repair the electrical connection. * Debris in the solution tank might be blocking the output hole, so clean the tank. * The solution hoses might be clogged with debris, requiring cleaning.

      If the solution is dispensed even when the KENT Floor Machine is off, it could be due to: * Dirt or calcium deposits on the solenoid valve gasket, requiring cleaning. * A broken solenoid valve, which would need replacement.
