Hello Michael, it was bought in October 2010. I've got a moderate load of washing in it just now which is due to finish in 35 mins, so will see if it's drained okay then. It's making the noise with that.
I had a fairly light load on yesterday, 2 sheets, and 1 small towel, when I noticed the issue. I'm fairly sure it had drained, just that everything was still soaking wet. There was a fair amount of water came out of the filter pipe when I cleaned it.
It sounds more like the drum making the noise, going by the direction the sound is coming from and it's in sync with each initial move of the drum. I'm not sure what the drain pump would sound like though.
Thank you Michael, I'll have a shop around for the price of the springs and tool and decide whether to go ahead myself or get someone in.
