Probably not heating or is intermittant heating. Usual problem is blockage in small pressure chamber in left hand side of machine at bottom and the front hose leading from it to the sump. Ignore blockage in tall plastic chamber at top you cant clean it out and it doesnt cause a problem.Remove large chamber and catch water from it , mark plugs and remove from micro switches,remove small chamber and hose, remove top micro switch and black arm, prize off clear plastic lid and clean out
