you know i just decided to pull it more apart and removed the dish holder and the sprinkler and the base mesh plate and the centre driver...it's Fisher and Paykel.....and under the bottom mesh in the top washer was a mass of residual powder and it was fairly grotty ..the bottom washer wasn't too bad...gave them a good clean and now got them both running on heavy cycle with nothing in them except fresh powder...see if that helps...won't help them scrub though..lol
