Hi,
Looking for some help.
I have a Bosch SMV53A00GB/19 that isn’t heating water or drying dishes and showing error code E09.
I have got the heater pump out – part number 651956. I would like to test it before I buy another and refit, given the price.
Anyone got any advice on how to do that? Only advice on the subject I can find is this thread, where the information on testing doesn’t seem to match what I am seeing, which is the following:
Any help would be greatly appreciated!

three large terminals
1 is earth
the other 2 are the heateryou should get a lowish ohm reading with a multi meter between 2 of them

Thanks for the reply.Yep, I got that from the plug that came off the terminals, left pin is ground, other two are live.
Sorry to be clueless about this, but do you mean between the two lives or one of the lives and earth? What sort of range am I looking for a working circuit and one that is broken?
Thanks again.
Re: Bosch SMV53A00GB/19 Heater Testing
they are not two lives. When its on one will be live the other will be neutral
cant tell you exactly what to expect but if its over 1000 ohms then its gone
the problem comes with why is it
1 just failed because it wanted to
2 blocked filters
3 diverter valve faulty
4 blocked bars2, 3 and 4 in other words anything that lowers the flow rate causing overheating

So I have had the multimeter on it, I don’t get any reading at all no matter what combination of pins I try. I haven’t used the multimeter in a while (thinking from both a knowledge and reliability perspective), but I tested a fuse and lightbulb on the same setting and got a low reading on both, so I don’t think I am being totally inept here.
Does this point to the heater being dead, or are things still inconclusive?
Re: Bosch SMV53A00GB/19 Heater Testing
You should get a reading no matter how confident your skills, so that points to the element being at fault. A very common failing and regular occurrence especially if you don’t put salt through the integrated water softener. 🙁
Final thought: If your multimeter has an audible continuity test setting you could test it with that

Back up and running!
Thanks for all that helped me out, wasn’t too hard in the end.
For anyone who might find this in the future…
New part arrived, 20ohm reading with the multimeter on the right two large pins in my picture which gave me some confidence that the original was dead. Fitted it back in and hot water has returned.
This video was perfect for showing how to remove the part with the least amount of hassle – https://youtu.be/BKAQmq9MPN8
Cheers!
