My Hoover AAA 1400 stops mid cycle with what was an error 4. My husband cleared the filter thinking this was the problem and it now stops mid cycle with error 3. We can manually move it to spin and rinse to complete the wash. At £110 for a Hoover call out since the machine is over 5 years old I am tempted just to put this to a new machine but the green person within me tells me to get it fixed!! Does anyone know what the problem could be?
