Bosch Maxx WFL 2260 making intermittent noises. Our machine works well but of late it has taken to making a graunching noise (similar to what you get in a car when you don't use the clutch properly). It does it about 5 times per cycle, each one lasting from a second or two up to 10 seconds, sometimes with the drum rotating and sometimes when it is stationary. I can't make the noise by rotating/rocking the drum by hand. It could also be described as a stone rattling about in there somewhere but as it does it when the drum is not revolving, I'm not certain that it has anything to do with the this part. Thanks for any advice. Steve

It makes the noise with the drum stationary on occasions, so the drum can be ruled out I guess. It doesn't make the noise for the first Half hour which is when the pump first kicks in. Each pumping spell it makes the rattling noise on average 4 or 5 times over 1 to 4 seconds. It makes the noise with the drum stationary on occasions, so the drum can be ruled out I guess.

Cracked it! A 5p coinmust've got past the filter and the pump kicked it up the outlook pipe. Every so often it would fall back into the pump vanes and make a noise before being kicked up the oupput pipe. The 4th time of taking the filter out the 5p coin was there on the bottom below the vanes. Took it out and all is now quiet. Thanks for your help Paolo. Steve Cracked it!
