I tried this although in my machine the 'extra rinse' button is not there but a half load button instead. I never the less used this button & what happened is as described. I only needed to turn the dial 8 turns, 40 degrees light wash & the unit made a few cycles then spun at top speed. So far ok. Unfortunately this seems to have upset the programmer which does not follow it's normal pattern of events.
Don't know what to do now except, maybe experiment to get a full wash the go through the procedure again to spin.
Any further help would be appreciated,
