Accessing Bosch dishwasher Service manuals

Hi @dai11869

I've never found any Bosch, Siemens or AEG dishwasher service manuals available online, not even to buy, only a few washing machine service manuals and they were USA models.

The best that you can do is find the parts list to help find any replacement parts and a very basic troubleshooting guide based on any error codes and problems being displayed by the model, but that's about all.

A common problem with Bosch and Siemens dishwashers is that the flowmeter (example only) goes faulty, so the dishwasher doesn't know how much water is in the machine when filling, so it stops. It may even stop a second or two after it starts, because of this problem or when it does a 2nd wash or rinse in the washcycle as it may be an intermittent problem.

With most models it is situated on the left side of the cabinet (when facing the dishwasher) so you need to pull out the dishwasher and remove the side cover. If you have an Ohmmeter, once you remove the flowmeter you can connect the meter to the flowmeter contacts and then blow through the flowmeter tube, to turn the impeller and check if there's pulses seen on the meter. The control board counts the pulses to know the amount of water flowing in the machine.
