My mother in law decided to help wash up some dishes (bless her) and didn't realise the milk frother jug (yes we are posh--not) was electric ..so after fishing it out the wash up bowl it doesn't work. Opened it up and dried off best I could and sat it on radiator but still no joy. Fuse ok in plug. Don't know what bit inside doesn't like water. Bsially has a motor, switches and a heater and a cut out when milk reaches right temperature and also some kind of timer when it froths cold milk. Doesn't power up on any setting. Separate base unit that plugs in but this didn't get wet.

May be an over-temperature cut out which is also soluble?

If its electronic, I'd leave it for at least a week to dry out thoroughly after opening it up to the air as best you can.

Otherwise its probably cheaper to buy a new one than get it repaired. But contact the manufacturer for advice. They may fix or replace it as a goodwill gesture.
