I don’t understand the last comment.

>>>In the Ebay link there are a number of machines listed re compatibality.I checked a couple on the Siemens site and the same part number cross references with the OP’s machine.>>>
This means the parts are correct?

Well the Ebay listing could be wrong but its easy to check a few of the Siemens models yourself(as detailed in the listing)and you will see they are the same part number across the models as yours.

I can just switch the motor assembly right? Its the aqua sensor that I can’t switch? But if I only switch the motor ass, and not the complete heating element then I won’t need to worry about the aqua sensor one way or another. So the cheap one on ebay will work. If I just switch the motor ass. is this a lot less work then doing the whole heating element. And all that is wrong is contained within the motor ass,?

Yes You takes your choice £££ for a new part or try the low cost option which imho will give you the motor swap parts you need.

eh…what?

Re: lower spray arm not working

One final question.

Before I go through all the work to replace the motor, what is the chance this problem if from the water inlet valve. Our water is very hard. Would a clogged water inlet valve cause the same spray arm not rotating problem. I cleaned the aqua stop but not the inlet valve.

No the aquastop is the inlet valve hence you would get no spraying at all

Have I missed something here? What’s the problem with “the motor” ?

Re: lower spray arm not working

It’s my understanding that the little black (motor) part that sits on top of (or is it on the bottom) attached to the heating element is really the part that is not working. Do I have this wrong?

If I run the dishwasher, it definitely heats up. So technically, although I must purchase the whole heating element because parts are not sold seperatly, it’s only the black motor attached to it I need.

Hey, if I have this wrong let me know a.s.a.p….please.

I ordered a used part with a one year warranty.

Also, can somebody please give me some details about how to replace it. Is it best to put the machine on its side so that I can access the bottom? I removed the front ‘kick board’ panel and took a look around. Can see the part but can’t reach the part from the front, or at least not without removing a lot of other stuff first.

I looked all over youtube…no help there. At least not for a siemens.

Find a Siemens dishwasher engineer near you

Fitting the motor to the bottom of the heater unit will NOT work….OK?

The whole machine has to be dismantled from top to bottom (in that order) Lid off, door off, panels off, stainless tub off….the rest is obvious. Best of luck.

The motor diverter unit fails primarily as a result of the plastic cam unit swelling over time due to heat and detergent damage. Also, very often the water seal seal fails and the gears bind. Therefore the only effective solution is to replace the complete Instanteneous Heater Unit (Pt No. 488856)

HTH? 😀
