The short answer
When cleaning falls off on the Cafe CDP family it usually does so gradually, which points at accumulation — a fouled filter, blocked spray holes, scale — rather than at a failure. One model tag covers this family in the matrix below, which keeps parts ordering simple and leaves the whole of the diagnosis to the symptom. A sudden loss of cleaning between one load and the next is the pattern that points at the wash pump or the diverter instead.
What you can observe on these models
- Detergent left caked in the dispenser cup at the end — The cup opened into a cycle with no water flow, or an item in the rack blocked it from opening at all.
- Plastics come out wet while china is dry — Normal for condensation drying: plastics hold too little heat to evaporate their own film.
- Spray arm holes visibly blocked — Seeds, labels and scale close the small holes first, which drops coverage long before it drops pressure.
- Baked-on soil on items that used to come clean — A gradual change like this is accumulation in the filter or the sump rather than a component failure.
- NEAR MISS — the cycle never starts or stops early — A control or latch problem produces dirty dishes without any wash system being at fault.
Causes, most likely first on this family
- Spray arms blocked or unable to turn — Ranked first because it is the one cause that is both free to check and visible: spin each arm by hand and hold one up to the light.
- Filter and sump screen fouled with soil — Second, and the cause behind almost every complaint that developed gradually over months.
- Wash water not hot enough — Third: detergent needs heat to work, and a long run of cold pipe between the heater and the machine means the first fill is effectively a rinse.
- Detergent type, dose or an empty rinse aid reservoir — Fourth, and the first thing to change when the complaint is film rather than grit.
- Wash pump, diverter or heating element — Last: a genuine part failure usually announces itself suddenly, and it is a poor explanation for a slow decline.
Check in this order, and why
- Spin both spray arms by hand — They should turn freely through a full revolution with nothing catching. Anything that stops them stops the wash.
- Pull the filter and rinse it under the tap — On these models the filter twists out by hand. A packed one recirculates soil and is the commonest single cause.
- Hold each spray arm up to the light — Blocked holes show immediately. Clear them with a toothpick rather than a drill bit or wire.
- Run the tap at the sink until it is hot, then start the cycle — It costs nothing and removes water temperature from the list for the next load.

Safety
Switch the dishwasher off at its breaker before removing the filter housing, the sump cover or any panel — a capacitor can hold a charge after the power is off. Broken glass in the sump is the real hazard on the Cafe CDP family: use a gloved hand or a wet-vac rather than fingers, and never run a cycle with the filter removed.

When to call a technician
Cleaning the filter, clearing spray holes and correcting the detergent are yours to do as often as needed. Call once a part has to be condemned, or if the machine trips its breaker during the heated part of a cycle — that is an element or a wiring fault and it does not improve with use.
