I have a CUISINART CHW-12 and have to replace the two hoses....I can't find anywhere what size to buy. Can anyone help me with this please?

Most likely the heater is breaking down or may have over heated and the flakes are the corrosion breaking off on the heater itself.

Here's the manual:

Define plug. Electrical cord?

My first guess would be that the control panel above the carafe has a thermally sensitive component or poor contact that acts like a fuse when it heats up but is fine after a cool-down. If this is the cause, disassembly and detailed inspection are required. If you're handy with a low-wattage soldering iron (30W), you could resolder connections on on the controller.

My second guess would be that there may be an over-temperature circuit in this unit that removes power if the unit gets too hot (you don't want a fire and Cuisinart has has some history here). If this is the cause, there is a failed thermostat in the heating system.

You can download the manual from Cuisinart
