We have an Electrolux ESL 624 dishwasher which won't start. When you turn it on, it just makes a buzzing noise. I guess this is something to do with the outlet or inlet hose being blocked. I have never looked at the back of a dishwasher before, but am happy to have a go at fixing it. Does anyone have any knowledge of this particular model who could tell me where to start and which bits to unscrew? I think actually getting it out from its built in/under position will be the first challenge. Many thanks.
