I'm trying to change the washer on this wall tap (laundry), but I can't get the flange off. It has a spring but also seems to be stuck by the white plastic ring wrapped around the spindle. The cylindrical spindle surface seems to be smooth where the ring is, as far as I can see. I have tried to directly pull the ring off the spindle (by forcing the spring-loaded flange towards me), but this didn't seem to move the ring at all. I have not yet tried WD40 or the like. The front face of the ring has four radial projections sticking out. And since the ring is recessed inside the flange and difficult to access, I'm wondering whether some kind of tool is needed to unscrew the ring from the spindle? Don't want to break anything. Would really appreciate any advice.
