Re: creda model 37747 service manual
The float chamber is directly underneath the condensor chamber.
If you look at the back of the machine the small black rubber bung is attached to the float chamber outlet.
You can see the float switch if you remove the right hand ( from front ) side panel, its just behind the motor.
Access is very limited.
I have changed the odd float switch without removing anything else but it was very difficult indeed. 😥
It is possible to reach the float switch to test it though.
PS. It is not a good idea to start another thread on exactly the same topic, it only leads to confusion.
