Re: bf162 error
1+2 is a drain time out error, it is not emptying. The filters are not very good on these machines and pump blockages or obstructions are very common.
You will need to remove the base then remove the drain pump. The chances are that it will just be obstructed by a small piece of glass, bone, wood, china, sweetcorn etc.
You can find the pump by following the grey plastic hose into the innards of the machine.
Be sure to remove the mains plug and have a towel handy to place under the pump as you remove it to prevent water leaking into places it shouldn’t.
