Re: Bosch SGS43A42GB/01 won’t stop filling
Just a postscript to complete this tale.
The water-level sensing magnet is easily accessed in the front of the filter slot under a circular 2cm diameter cover. (Just remove the filter in the usual way then pull the little cover up with a finger.) Wiping the magnet to remove grease and replacing it cured the problem.
We’ll not be going for the float switch mod kit as the machine has proved to be rather unreliable and there’s little confidence in it now, so we’ll be replacing it with something else in due course.
