The short answer
Standing water in a dishwasher is a restriction, and the restriction is nearly always upstream of the pump: the filter, the sump, or the drain hose where it meets the sink waste. A small amount of water in the sump is normal on some machines; several inches over the filter is not.
What you are seeing
- Water covering the filter at the end of a cycle — Means: the drain step did not complete.
- The pump runs but the level does not fall — Means: a restriction downstream, or a jammed impeller.
- The machine drains and then refills — Means: a siphon from the sink waste or a missing high loop.
- Dirty water in the base with a clean cycle selected — Means: waste from the sink being drawn back into the machine.
- No pump sound at all — Means: the pump is not running or is jammed.
- Text: Observations that place the fault, and the near misses that mean a different one. Water under the machine rather than in it is a leak, not a drainage fault. A thin film of water in the sump between cycles is normal on many machines and keeps the seals wet.
Ranked causes on this platform
- Sump filter and its housing blocked — Why: Everything the wash removes ends up there, and a blocked filter stops the drain path before the pump ever sees the water.
- Drain hose kinked behind or under the machine — Why: The hose is squeezed when a built-in machine is pushed back into its housing, and the symptom appears right after any move.
- A condition the machine is signalling by blink pattern rather than by code — Why: Particular to this class of machine: the fault memory is a blink pattern that is lost as soon as the machine is reset, so an owner who resets first and looks second has usually discarded the only evidence there was.
- Sink waste or disposer connection blocked — Why: The machine usually drains into the sink waste, so a blocked trap or an unremoved disposer plug stops it completely.
- Object or debris jammed in the drain pump — Why: Glass, seeds and labels reach the impeller and stop it; the pump then buzzes without moving water.
- Missing high loop or air gap allowing back-siphoning — Why: Explains the drain-then-refill and dirty-water patterns exactly, and it is an installation fault rather than a machine fault.
- Drain pump failed — Why: Identified by silence at the drain step after every restriction has been excluded.
- A standard part looked for under the retail name instead of the plate — Why: A documentation problem rather than a machine problem: sump filters, spray arms, inlet hoses and drain pumps for this class are stocked items, catalogued against the model and product numbers on the plate inside the door.
- Text: This is a full-size European built-in dishwasher, and two design decisions shape the ranking. The sump is filter-first: the machine expects the owner to clean a filter, and it recirculates whatever that filter fails to catch, which puts the filter at the top of nearly every list. And the machine reports faults by blinking a programme light rather than by printing a code, so the pattern the panel shows is read as evidence rather than looked up as a code. One more factor belongs in the order here: this is a retail house name on a machine built by a mainstream assembler, so the parts are standard European built-in items — but they are catalogued against the plate inside the door rather than against the name on the front.
What to check, in order
- Record the blink pattern before touching anything — Why: On a machine that signals rather than displays, the pattern is the only fault record it keeps, and every reset erases it.
- Listen during the drain step — Why: A running pump and a silent pump split the fault tree in half before anything is opened.
- Bail out the water and remove the filter — Why: The top-ranked cause, and the machine has to be emptied before anything else can be reached anyway.
- Clear the sump and check the pump impeller by hand — Why: Follows immediately because the sump is directly under the filter you have just removed.
- Check the sink waste and any disposer connection — Why: Placed here because a blocked waste stops the machine draining while the machine itself is perfect.
- Check the drain hose route and its high loop — Why: Last of the free checks, and the one that explains refilling and dirty water.
- Read the model and product numbers off the plate inside the door before ordering anything — Why: On a house-brand built-in the plate is the catalogue key, and the retail name on the front will not find the part.
- Text: Each step either finds the fault or removes the next most likely cause from the list above.
Step by step
- Note which programme light blinks and how many times it blinks between pauses, and check that pattern against the fault list in the manual before you reset the machine. — Tools: pen and paper, the manual
About 15 min
- Start a drain or cancel cycle and listen at the base for the pump. Note whether you hear a hum, a buzz or nothing. — Tools: none
About 5 min
- Switch off at the spur. Bail the standing water out with a cup and soak up the rest with towels. — Tools: a cup, towels
About 20 min
- Twist out the filter assembly, wash it under a hot tap, and clear the sump underneath by hand, watching for glass. — Tools: gloves, a brush
About 20 min
- Check the drain pump impeller in the sump turns freely and is clear of labels, seeds and glass fragments. — Tools: gloves, a torch
About 10 min
- Under the sink, check the waste trap and, on a machine connected to a disposer, confirm the knock-out plug was removed at installation. — Tools: a bucket, a wrench
About 25 min
- Follow the drain hose from the machine and confirm it rises to a high loop under the worktop before falling to the waste connection. — Tools: a torch
About 15 min
- Open the door and photograph the plate on the inner frame, recording both the model number and the product number before ordering any part. — Tools: a phone camera, a torch
About 10 min
- Text: Checks a homeowner can safely make. Stop at the first step that would need a meter on live terminals.
Safety first
Safety
Switch the machine off at its spur or breaker before bailing water or reaching into the sump; a dishwasher combines standing water with mains voltage. A capacitor can hold a charge after the power is off. The sump collects broken glass, seeds and knife points — wear gloves and look before you reach in. Wash water may be hot enough to scald immediately after a cycle, so let it cool first.
When to call a technician
Call a technician when the filter, sump and impeller are clear, the sink waste runs freely, the hose has a proper high loop, and the machine still will not drain — or when there is no pump sound at all. Bailing, filters, the sump and the waste connection are owner work; the pump is not. On a built-in machine the boundary also has a practical edge: the filter, the spray arms, the seal and the drain are reachable with the door open, while anything that needs the machine drawn out of its housing is a service visit.

Common Essentiell Dishwasher Problems — Slug: essentiell-dishwasher-problems — Relation: the routing page for this brand and appliance
This page is generalized information. It covers Essentiell dishwashers as a class: it carries no model numbers, no family-specific error-code table and no wiring detail, because no fact rows for those exist behind it. European built-ins of this generation share sump filters, spray arms, inlet hoses with integral flood valves and drain pumps across several assemblers; the part is matched by the model plate inside the door. On a machine that signals with a blinking light rather than a code, note exactly which light blinks and how many times before you touch anything — that pattern is the only fault memory the machine has. The more specific pages listed below sit beneath this one, and where one of them differs from anything general said here, it takes precedence.
