i took mine apart found out the 8 cavite canister was caked on dirt i washed that all out and the water was black ( eewwwww ) took a bit of time but i got it all cleaned out that i could, i didnt get 100% since i didnt want to break anything, if it didnt move after the scews and a bit of force then i left it and used a presure nosil on my water hose, after it was clean it ran aloot better then it was, we had the machine in for repairs so they can fix it but it never lasted but a few months and back to repair shop, after all my washing the casinster parts and put it back together. next time we take it back will be for a boken part.
