This video demonstrates how to clean the Huebsch & Speed Queen drop coin mechanism. The Munzprofer drop coin mechanism can collect lint and prevent the quarters from registering or producing an “Err” error on the dryer computer. Cleaning the dryer drop coin mechanism is a routine preventative maintenance procedure. This video goes through the simple procedure of opening the drop coin unit, cleaning the component and then re-assembling the mechanism. Keep your laundromat up and running!
