Empty water button staying on

Remove lower left filter from dryer, and wash it out under running water. Reach inside the compartment and clean any fluff and gunge you can find there.
Get a plastic bag tie or similar, and feel for and locate a small hole at the rear of compartment, poke it clear with bag tie.
If you are certain that the element and stats are o/k , and it still does not heat and the light stays on, then that indicates that the float switch is stuck or is faulty.
To access this involves stripping the dryer down, not an easy job.
Plz rate my solution.
Thanks.
