I had the F18 error code, I have emptied machine manually and cleared filter, I have also switched machine off to reset computer but still receiving error message when attempting a wash. Is there anything else I can do? otherwise engineer on way end of week, cheers.
you hve an emptying issue, even though you have checked the filter the pump itself may be worn and not emptying or there may be an obstruction in the sump hose set it for drain and with the filter removed see if the impellar spins, if it spins its the sump hose thats blocked
