How can I fix my Simpson EZIset 550 washing machine?

Over filling. Start by checking the water inlet valve is shutting off ok. Start the fill process, then while water is flowing in press the pause and water flow should stop quickly. If it continues to flow or hesitates for a few seconds before shutting off, the valve is faulty and should be replaced. Try that 3 or 4 times to be sure. If valve is ok then check the rubber air hose which goes from the r.h. side at rear of bowl up to the control panel. Take the back panel off. Check the length of it for holes. It may of been rubbing on the cabinet. Air is pushed up that tube while it is filling. The increase in air pressure tells the machine when to stop filling. So you want to make sure it is air tight and no leaks.
