Dishwasher not heating or washing one rack well?

In many dishwashers the wash water passes through a heater housing on its way from the pump to the spray arms, and a diverter then sends that flow to the lower or upper arm, or alternates between them. Trouble in this assembly can show up as cold water at the end of a cycle, dishes that come out greasy or wet, heating error codes, or one spray arm doing little while the other works. Cracks in the housing can also cause leaks under the machine.

Fitting the heater and diverter assembly

Turn the dishwasher off at the wall and close the water tap, then bail out any water left in the sump. This assembly sits in the base, so the machine usually has to come out of its cavity for access. Photograph the hoses and wiring, fit new clamps where the old ones are tired, and check for leaks during a test run.
