I am freshly after fixing the error E36-10 in the Bosch washing machine series 4.
The cause is a malfunction in the system of draining the washing machine of water.
In practice: the filter and attention.... drain hose and the drain itself need to be cleaned.
The symptom is that the washing machine signals an error when it should be spinning or drawing water (for example, for rinsing).
Cleaning the filter: no philosophy, but there may be a problem with unscrewing it. Often it is not a problem of scale, which was mentioned in a post, but those little things that blocked the pump (coins, paper clips, etc.).
To unscrew such a blocked filter, it is worth moving the washing machine away from the wall and tilting it at an angle "on the back".
It is worth draining the water in advance with an emergency drain hose.
In addition to the pump, remove the drain hose from the drain in the wall and clean it at the outlet (in my case there were fibers from fabrics at a length of about 8-10 cm).
It is worth testing the patency of the hose by draining water into a bucket, tub, etc.
Another thing is to check the patency of the drain in the wall (it gets clogged, especially when using liquids).
I unblocked by inserting a garden hose and under pressure letting water in (in the block of flats more difficult).
After such unblocking: the pump, hose and drain, the washing machine hulks and there is no error.
Good luck.
