Remove power cord from outlet. Remove top and bottom panels. Drain and clean filter - used a shallow oven tray to catch water. Watch YouTube video closely. Remove hose as vid, very easy.
Only tricky part is getting the new hose on to the tub. The clamp tabs are wide apart, use vice (mole) grips to hold the clamp tabs together and allow hose and clamp to fit onto top outlet.
You may then need pliers to grip again if the hose needs to be slightly adjusted into place. The video does it this way, but you need to watch carefully to see it.
Check for leaks during wash. Done.
