De-gunging a deep-fat fryer ?

[Peripatetic Phil]

Sorry, I realise that I'm talking about using a sink and hot water and you're talking about a dishwasher.

Well, not only a dishwasher : I have used the DFF to heat itself, but containing water + detergent rather than oil; I have washed it in the DW at the most powerful setting; and I have washed it in a sink.  Anyhow, it's now as clean as it's ever likely to be, so with sincere thanks to all I think we might let this thread die a natural death
