Start here
An Essentiell machine that has stopped cleaning properly rarely needs a part. It needs the filter out, the sump cleared, the arms free to turn and a detergent and rinse-aid routine that matches the water. Only after those are settled does a heater, a sensor or a pump belong in the conversation, and then it is a service call.
How the fault presents
- Detergent tablet found whole in the base — The dispenser never opened, or the water never dissolved it.
- Plastics wet, china dry at the end — Residual-heat drying behaving normally: plastics hold less heat.
- Gritty deposits left on the bottom rack — Soil that was washed off and put back, which is a filter and drain symptom.
- Dried-on food on the upper rack only — The upper spray arm is not getting water or cannot turn freely.
- NEAR MISS: the cycle stops part-way and leaves standing water — That is a cycle or drain fault, and the results are a side effect.
Likely causes in order of odds
- Low water pressure, a kinked fill hose or a cold-only supply — Most likely on this platform: this badge belongs to a retail chain rather than a manufacturer, and a fill restricted by a kinked hose or a half-open service valve starves the spray without producing any error.
- Filter, sump and spray arms fouled — Next in order: it is the cause that best explains grit on the lower rack, it needs no tools, and it is the cheapest thing on the list to rule out.
- Overloading, shadowing and the wrong cycle — Third: water travels in straight lines, so a plate leaning across a jet protects everything behind it, and eco cycles are short on both heat and time.
Where to start, and what follows
- Check the service valve is fully open and the hose is not kinked — A restricted fill gives a weak spray, long cycles and poor results with nothing actually broken.
- Pull the filter, clear the sump, spin both arms by hand — Arms should turn freely and every jet should be clear.
- Reload the machine deliberately and run the full cycle — Nothing blocking the arms, nothing nested, cutlery separated.
The checks to run before calling anyone
- Take off both spray arms, clear every jet and refit — A pin or a toothpick for the jets; check each arm spins freely.
Tools: toothpickAbout 20 min
- Run a maintenance wash on the hottest cycle, empty — Strips grease and scale so the next real load is a fair test.
Tools: machine cleanerAbout 90 min
- Top up rinse aid and salt if the machine takes them — Film on glass is usually a rinse-aid or water-hardness problem, not a fault.
Tools: rinse aidAbout 10 min
- STOP HERE if the machine is clean and the wash is still weak or cold — Pump pressure, the element and the sensors are all measured inside the machine with the power isolated.
Before you open anything
Safety
Power off at the breaker before any panel comes off. Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. allowlist:unplug-before-service
Where the owner fix ends
Call when the filter, sump, arms, rinse aid, loading and cycle choice have all been addressed and the results are still poor, because what remains is pump pressure, the heater or a sensor. Make it sooner if the machine finishes cold, since no heat is a fault rather than a habit and it is measured rather than guessed.

Generalized information, and where the specifics live
Treat this as generalized information about an Essentiell machine. It does not claim to describe your exact family or build, because this badge covers several contract-built platforms and they are not wired the same.
