Hi, yes I know it is as old as the hills but its mine and its paid for! What Om looking for is the upper spray rotor- the bit that goes round spraying out the water.
The plastic at the center of this has a plastic nut. The threas has gone on both the nut and the rotor as the plastic seems to be de-composing!
Where should I go for spares and may be a service manual?
You may be out of luck here. The exploded diagram is still on the data disc, but there are no part numbers listed anymore. This generally means that they’ve called it all obsolete. Unless anybody else knows better?
