Re: Miele W3240 – Too much detergent error.
its a fault miele are aware of, but can only be fully fixed by updating the firmware with a laptop…. what it does is to change the way the machine spins after the main wash…so it ramps in 200 rpm incraments instead of going straight to 600 rpm…. this stops any excess detergent causing the pressure sensor to activate as the drum pressure increases during the spin…..
it is also caused by a blockage in the venting system from the pump to the upper dispenser hose…as the drum also slightly pressurises during drain..
