The rotating arms don't work - Bosch Dishwashers

Posted by on

  • acros Sep 04, 2008

    It's a S9J1B integrated Bosch dishwasher.

    Neither spraying arm is rotating, although there is cold water coming out of all the holes when it starts the cycle.

    I'm assuming the pressure must be low (i.e.

    blockage?)

    I haven't attacked it with a screwdriver yet - simply cleaned and removed all the "removable bits".

Problem may be the spray arms blocked and this is not always apparant. they only rotate with water coming out of angled jets at the end. worthwhile taking the spray arms off, run water into the centre hole and see if anything comes into view
pump is an induction motor so normally would run at constant speed.

The bottom arm on my Diplomat dishwasher does not rotate during the wash cycle. All of the holes in teh arm are clear and the arm on the upper basket works fine.


Does the arm rotate if you turn it by hand? If it does. and the top arm rotation is normal, there must be a blockage further back in the piping. Remove the arm, it us usually held in place by a nut or a clip, and check the hole, even try operate it without the arm so see if it will dislodge anything. Also check the inside of the arm again, there may be something there that you did not see earlier.

The top arm will not rotate.Have checked to make sure that no holes blocked and arm rotates freely.Bottom arm works ok


Check the transfer pipe that takes water to the top arm, it could be cracked, loose, kinked or blocked. Try back pressurising it from the top rotating arm attachment pipe. This will give you an indication where a leak could be or blow out a blockage.

The dishwasher has three arms in it. The top and bottom arm do not rotate. The middle arm rotates fine. The arms will move when manually munipulated but do not spill while the dishwasher is on. There was a...


sounds like maybe some rinsing salt was spilled when the salt reservoir was filled the first time (or broken glass, this always used to be an issue in catering) and got pumped through, lodging in the gap between the arm and it's mounting. this can roughen the two meeting faces of plastic and cause them to jam up.
remove the arms and examine the state of the plastic, also look for granules/particles of glass. if it was salt it will be long gone...

Check the free rotation of the spray arm. If arm jets are clogged clean them.

After placing the dishes see to it that, the arm is freely rotating without any obstacles.

Try rotating the spray arms by hand. It should rotate freely. If possible clean the arm rotating place by removing them.

Arms rotate by by pump pressure only. finally check the water pump also.

The bottom washer arm does not turn or squirt water


Hi Matt.
The lower housing underneath the lower wash arm may still have something blocking the water passages.

If the spray arm is clean and it freely rotates try lightly pressing down on the wash arm and then rotate it. Your checking to see that when water is applied to the spray arm it forces the arm down against the lower housing tower and hopefully does not lock up. If it does lock up while pressing down and rotating obviously you need to find out what the cause is.

You may have to remove the lower wash arm housing and clear the debris from the water passages. Once the passages are clear it should work fine.

Thanks for using FixYa,

Upper basket spray arm


Have you checked that the cover for the water inlet at the top where it connects to the spray arm is attached? It could have worked loose. Just re-attach and your spray arm should "miraculously" start rotating again!!
