I know its 2 months late but here goes. At the link above look at 1 and 5, the bowl/fryer pan on the cf154 model can not be removed. So it has to be washed like any other non-imersable cooker, wipe it out with paper towels and put a little soapy water in the pan and scrub it out then dump the water out and rinse the same way, never imerse the intire unit in water. dry with clean paper towels.
the basket and lid can be washed in a dishwasher, IF you remove the filters from the lid.
Outside should be cleaned with damp soapy sponge (no scratchy pads) and rinsed the same way and wiped dry, be sure to get into the tight corners around the pans lip and other places oil will collect over time.
All fryers of this type are going to get grungy over time no matter how well you clean it due to the fact it can not be taken apart and cleaned so oil is going to build up in places you can not get too.
