Bad news
spider!
Maybe the bearings too
About price, I don't want nothing more than the cost.
Open your machine and check which parts you need. This model is very similar to the LE750 we had here in Brazil until a few years ago and this model still being produced for Agentinian and Paraguayan markets as EW757.
You don't need ultra advanced skills or wierd tools to open it. If you have msn or yahoo messenger and a webcam that can reach the machine I can also help you with technical instructions in real time.
If you need a bearing only the freight might be insignificant, but if you need the spiders, drum or the Tub I think it will bevery expensive, but maybe not prohibitive.
As I have access to the Electrolux Intranet, I can check the parts list and exploded views to see if the parts are exactly the same and also know each part's price.
How old is that machine? can't you find parts for it? Sometimes they can be much cheaper to fix than one could imagine.
I don't remember much about this model, but I remember clearly it was a very strong Zanussi based machine and I'm sure it worths all the efforts to save it.
By the way, the gasket belt clip is loosen. center the gasket (there's an arrow on it's top that must match the arrow on the cabinet) and hand tight the belt clip. This has nothing to do with the issues that made you start this thread. But I saw it by the pictures.
As the drum is moving when you pull it, stop using the machine immediatelly otherwise you can cause HUGE damages to the drum and the tub.
