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.
- The machine being asked to work beyond its designed capacity — Why: Specific to compact appliances and easy to miss because nothing has failed: a load, a room or a duty cycle that a full-size machine would handle without comment is at the limit here, and the machine reports it as a performance complaint.
- 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 machine installed into a space that does not suit it — Why: Very common on countertop and compact appliances: an intake against a wall, an exhaust under a shelf or a cabinet standing on a flexing worktop produces performance complaints in a machine with nothing wrong with it.
- Text: This is a compact dishwasher, and compact machines fail differently from full-size ones. Capacity comes first: the drum, the pump, the fan and the water path are all smaller, so the machine is far more sensitive to being asked for a full-size result than it is to any component defect. Restriction and load causes therefore rank above component failure throughout this list, and installation — clearance, levelling and hose routing — is part of the fault picture rather than a preliminary to it. One habit matters more than any component on this badge: these machines are bought to fit a space, so they are frequently installed against a wall, under a shelf or on a worktop that is not level — and the ranking has to account for the installation before it accounts for the machine.
What to check, in order
- Check the installation and the clearance around the machine first — Why: Compact appliances are put where they fit rather than where they work best, so a blocked intake or an unlevel worktop is a live cause on this platform rather than a background condition.
- 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.
- Look at where the machine is standing before looking inside it — Why: On a countertop or compact appliance the space it was fitted into is a live cause, not background, and it is visible before anything is opened.
- Text: Each step either finds the fault or removes the next most likely cause from the list above.
Step by step
- Measure the clearance around the machine against the manual and confirm nothing blocks its intake or exhaust, then check it stands level on a firm surface. — Tools: a tape measure, a spirit level
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
- Step back and check what is above, behind and beneath the machine: an intake against a wall, an exhaust under a shelf or a surface that flexes all cause faults the machine will be blamed for. — Tools: a tape measure, a spirit level
About 15 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 compact machine most of the boundary sits in the installation and the load rather than inside the cabinet, so work through both fully before booking a call.

Common Euhomy Dishwasher Problems — Slug: euhomy-dishwasher-problems — Relation: the routing page for this brand and appliance
This page is generalized information. It covers Euhomy 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. Compact appliances of this class use commodity pumps, fans, float switches and heaters matched by fitting; the model plate on the back or the door frame is the only reliable identifier. Countertop and compact machines are frequently used on a worktop that is not level and beside a wall that blocks their exhaust — check the installation before the machine. The more specific pages listed below sit beneath this one, and where one of them differs from anything general said here, it takes precedence.
