The flow meter is a small turbine that measures the flow rate by counting the number of revolutions. It can have various faults: often the thin inlet channel is dirty, or the water stops flowing further down the line, e.g. because the heater is calcified. The sensor may be defective, in which case you will need to replace the flow meter. Here we show you how to remove, open, and repair or replace the flow meter.
Note: Some of the images are from an older model, but this should not affect the repair.
‘'These instructions can also be used for other Siemens/Bosch models – the models are similar in design.’'

The side panel is essentially held on the ground by five strong catches. Pry up the pegs with a strong prying tool. It's pretty difficult and you need a lot of strength.
-
If the catches are loose, you can pull the side panel away from below. But it's still stuck in other places.
-
Use a plastic tool to pry the top cover up a few millimeters and lift off the side panel. Most of the time it's still stuck, especially at the front edge, you have to pull hard.
