Have a beko dfn05x10w which won't fill- -and now won't switch off? Is there a reset button??

Turn it off at the mains switch for 5 minutes. It might reset it.

Possibly a lid switch problem

Probably a control board issue if valve dies eventually cut off, most likely from overflow switch.

Lid switch is failing

That is a code for water fill issues. Here is a repair video which will help you find the exact problem--and fix it yourself:

My washing machine beko WME7247W won't do anything it said C on it won't start change tem do anything can you help me

See if the filter is clean or if the exhaust hose isn't blocked.

I have no real experience with float switches on dishwashers, but have with some in humidifiers. It's a piece of styrofoam on a narrow metal stick that lifts when the appliance fills with water & lowers when the water empties. If this gets stuck on something, like a dishwasher rack, the unit won't fill or empty the water & the cycles won't work properly. Take a look & see if there is such a thing hung up somewhere in the dishwasher. If you can loosen it, your dishwasher should work again.
