The machine can fill and drain perfectly while any of the three has stopped, which is why “it is not cleaning” and “it is not draining” are different pages here. ### What actually goes wrong - **A spray arm that will not turn** — the cheapest thing on the list and worth checking by hand. - **Jets blocked with scale**, which in this water is a maintenance item. - **The diverter**, which is what a single failing rack usually means. - **The circulation motor**, which is where the figure comes from. ### Why this costs more than the drain row Access. The drain side is reached from the front and the base; the circulation side means the machine coming out of the run, behind a panel that is your own cabinetry, under a counter that does not move. What this involves Diverter position identified from which rack is failing Spray arms and their bearings checked before parts Machine drawn out from under the counter as part of the job Which rack, and which cycle Upper only, lower only, or both, and on every program or only the short ones. That is the diverter question and it is answered from the kitchen rather than from under the machine. The free things first Spray arms that will not turn freely, jets blocked with scale, and the filters in the base of the tub. All three imitate a failing pump and none of them costs a part. Draw the machine out On a fully integrated machine the custom panel comes off and the appliance comes forward out of a stone-topped run. That is planned time, and it is why this row is priced above the drain row. Prove the motor and the diverter separately A circulation motor that has lost pressure and a diverter that has stopped switching are two different parts producing one complaint. The circulation side A pump that pressurises, a diverter that sends the water up or down, and two spray arms that turn. The machine can fill and drain perfectly while any of the three has stopped, which is why “it is not cleaning” and “it is not draining” are different pages here. What actually goes wrong A spray arm that will not turn — the cheapest thing on the list and worth checking by hand. Jets blocked with scale, which in this water is a maintenance item. The diverter, which is what a single failing rack usually means. The circulation motor, which is where the figure comes from. Why this costs more than the drain row Access. The drain side is reached from the front and the base; the circulation side means the machine coming out of the run, behind a panel that is your own cabinetry, under a counter that does not move. ### The top rack is clean and the bottom is not. That is a useful symptom rather than a vague one. It points at the diverter or the lower arm rather than at the motor, because a motor that has failed does not favor one rack. Say it when you book and the right parts come along. ### It is much louder than it used to be. Worth looking at. A Miele dishwasher is quiet by design, so a change in what it sounds like is a real signal — usually a spray arm catching, something in the sump, or a bearing on the circulation motor at an early stage. ### Does the custom panel have to come off? Usually yes, to get the machine out from under the counter. It goes back on the same fixings, and it is part of the job rather than an extra. --- **[Read full article: Dishwasher pump & motor repair](https://mielemiami.support/services/dishwasher-pump-and-motor-repair/)**
