Re: Bosh srs431c12gb/23 drain pump removal
Did one a couple of weeks ago – to only change the pump & not the housing. Remove plinth and metal plate from behind it and also outer door as this helps to give a bit more room to work. Remove transfer pipe from water inlet chamber to sump and the pump should just twist off.
If you need to change the complete unit I found that the easiest way was to also remove the LH side panel and remove the pump hose from the water inlet unit – attach a piece of string to the pipe – pull the pump out of the rubber bung in the sump and then draw the complete pump with hose and string attached carefully thru the front of the machine – and then after changing pump feed the pump and hose back whilst pulling the string back thru
-its fiddly but it works
