Thanks for the question.
please send me the complete model number so I can assist you better.
heres the breakdown of the model number, the # XXXXX is very important to keep clean its a very fine filter and grabs all the food particles.
not cleaning dishes, food particles and slime remaining on dishes. no rinsing clean.
had the machine for 5 years, never cleaned the filter. worked properly until last week.
theres a good chance its only the # XXXXX in the breakdown I sent you also clean in front of the door food always collects at the location, also make sure you turn the kitchen sink on first to get steaming water before you start up the unit.
