Re: Indesit 6100
The first thing to do is remove both spray arms and check for blockages in the small holes. This can be bits of food ( sweetcorn is common ), paper, glass, bone, wood etc. If these are blocked then removing the bits is often very difficult. New upper and lower arms are fairly cheap on these machines.
It pays to rinse the dishes first before you load them into the machine.
If the arms are clean without blockages then the fault is internal and may be best left to an engineer. Click the link in my sig if you need assistance.
please remove the mains plug if you intend to proceed further.
