A friend of mine going on holiday tonight needs me to try and source this part whilst he is away. I have not therefore seen the job but the part is described as ” The plastic nut that holds the uppermost (little) spray arm on. CDSL do list “nut spray arm”, but I cannot be sure this is the right part. Anyone got a part number?.
Thanks for your help guys, but seamys solution does not sound right. This part is threaded(about 5/8 bsp) and has like a nozzle through the middle, looks as if the jet from this powers the next spray arm down. Sorry to be vague but as I said earlier, I have not seen this job myself. The serial number is 15376047
Think the part described will do this, it secures top spray arm in position & allows water to pass through down to middle spray arm, funnel on middle spray arm is part # 3519600 if needed.
