I purchased parts for an Electrolux dishwasher bought from Costco ($1100+tax) as it was having I believe error code i20 on it. It was suggested that the error could be caused by three parts that were faulty. I bought all three but the first one I tried fixed it so I have a brand new water inlet solenoid ($52.21 p/n 807445904) and a brand new main control board ($255 p/n 117499400) that weren't used but can't be returned due to policy. The model of the dishwasher is EI24ID81SS0A.
