MIELE G7859 DISHWASHER FAULT CODE

I had this same fault code on the same machine and managed to fix it...............Turn off the power...then take out the bottom white basket so you can see the bottom inner of the dishwasher, then take out the centre filter and remove the silver L shaped plate so you can see down into the lower white inners......(may have water in it) on the left you can see a small white double dome with a silver clip going over it.....release the clip and pull off the dome inside you will find a pump wheel check this spins freely by flicking it round with your finger......if you cant see it due to water then either feel for it or remove the water.........if it does'nt spin...free it...if it does spin easily then put it all back together and do this...... turn the control dial so it points upwards to the Hazard warning shape.........then turn on the power......wait a minute and then turn the control to the water drain symbol (arrow pointing to water) then hit the green start button...all being well you should hear the pump you've just checked spinning and pumping the water out I did this and its worked fine since p.s. the machine reset button is hidden under the 2 plates at the lower front of the machine but the screws are tricky to get to. try the pump and control part first.

MIELE G7859 DISHWASHER FAULT CODE F26 anyone know what this code means and how to fix it ?

Hi .....F26 means the flood switch within the base has been activated ..........ya need to rmove base and raise of the floor and test on cycle looking for a water leak.

F76 Indicates that the float switch has activated.
Switch off the machine, roll it over on its side and remove the bottom panel.
Dry the inside and check all the hose conections and tighten as required.
I also drilled a hole in the base under the float switch to prevent it happening again

please could you tell me what I need to do?
