Hi. I have an Indesit IWME126 washing machine which has developed a problem which is probably due to a broken spider (or possibly bearings). I need to decide whether repair or a replacement machine is the best course of action. Could anyone please tell me if the drum tub is sealed (requiring replacement of the entire tub) or whether this can be opened up to replace the spider. It is a big job to remove the drum tub and not something I want to start only to discover I can't open the tub to complete the repair. Any advice would be much appreciated.
