I have a problem with water backing up in the vertical standpipe that the drainage hose is connected to. I've actually witnessed the overflow whilst the machine was draining.
The pipe is high enough above the floor (at least 24inches, probably more) and the ubend does not appear to be blocked (I've removed it and checked). There may of course be a blockage elsewhere, but water does seem to drain over the full course of the cycle. The actual overflow only **seems** to happen when the machine is pumping a lrge volume of water.
The pipe is not particularly thin and the hose is pushed down securley inside the standpipe, although only about 4 inches or so deep. But this should be enough. Also, the joints are all hand tightened.
I did think that I had fixed the problem, as it had not happened for a good few months after the first occurance. But now, after having moved the machine and then replaced it again (in the same place) the problem has recurred. It may just be a case poor installation, but I really don't think so.
I have read about "siphoning" and other drainage problems and am worried that there may be something going wrong that I cannot identify.
Any advice would be appreciated.
thanks very much.
