Quote:
the last time the washer was used it filled up with water and was unable to drain. The plumber had a look at it expecting a blockage, and 'unplugged' the pipe leading into the standpipe, and upon doing this it was able to drain.
Therefore he concluded that there is probably no fault with the washing machine and that the stand-pipe must have a minor blockage. He recommended that I pour some 'mr muscle' or bleach down the stand-pipe and then plug the machine back in and see what happens.
I'm a little confused, At first I thought the stand pipe was backing up, but that'sn notcorrect is it? (Or is it?) From what you say it wash the washer hose that was plugged and not the standpipe
