The rest of the wash cycle is normal so yes it does agitate although I haven't actually lifted the lid to watch it do that. The machine stops when I lift the lid during what should be the spin cycle.
I'll have to get back to you on that as I am not at home at the moment. I'll see if I can get my son to check it out as it will be quite a while before I get there.
My son has just confirmed that the agitator is moving during the wash cycle.
ok then its the clutch thats slipping , heres a diagram of the clutch assembly, its # XXXXX
tip the machine back and remove the bolts to pull the transmission down to get at it, you also need to remove the agitator there a bolt thats connected to the transmission shaft, you can order the clutch @ http://midwayparts.net/midwayparts/zen-cart-v1.3.8a-full-fileset-12112007/index.php?main_page=product_info&cPath=1&products_id=17 and it comes with instructions, thanks Bryan
Thanks Bryan. Your diagnosis seems logical and I fully expect it to work. I have ordered the part but don't expect to get it for several days. I'll let you know if it doesn't fix it, naturally.
