The short answer
A Ellipse dishwasher that leaves water in its base has a blocked path more often than a failed pump. The filter is the designed catch point and blocks first; the drain hose high loop and the sink air gap are next, and they are set at installation; the pump itself is last.
What you are actually seeing
- Standing water in the base at the end of every cycle — What it means: the classic drain failure — start at the filter
- The pump runs audibly but the water level does not fall — What it means: a blockage downstream — hose, air gap or waste connection
- Water drains slowly but eventually clears — What it means: a partial restriction, usually a loaded filter
- Dirty water appears in the base after the machine has been idle — What it means: back-siphoning from the sink waste, which is a high-loop or air-gap fault
Causes, ranked for an Ellipse dishwasher
- Blocked filter and sump — Food debris, labels and grease load the filter until flow stops. — Why this rank: Top of the list because it is the designed catch point and it blocks far more often than anything else fails.
- Missing or dropped high loop — Without a high loop or an air gap, waste water siphons back from the sink drain into the machine between cycles. — Why this rank: Second because it is an installation decision, it is invisible behind the machine, and it produces the dirty-water-when-idle symptom exactly.
- Blocked air gap or waste spigot — Why this rank: Ranked here because the blockage is outside the appliance, which is why a service call often finds nothing wrong with it.
- Kinked or trapped drain hose — Why this rank: Ranked here because it usually dates from the last time the machine was moved, which is a useful clue.
- Ranking basis: Ranked for this machine because the mechanical parts of this appliance class are near-universal, so they can be diagnosed and sourced without knowing whose platform this is.
What to check, and in what order
- Listen at the drain step for the pump running — Step: First — Why here: a running pump with no flow is a blockage; a silent pump is electrical or failed
- Sponge out the base and remove, rinse and refit the filter — Step: Second — Why here: the highest-yield action available, and it needs no tools
- Clear the sink air gap if one is fitted — Step: Third — Why here: a blocked air gap stops drainage completely while the machine itself is perfectly healthy
Checks an owner can safely make
- Note the model and serial from the rating plate, and search by symptom and appliance type rather than by brand name. — Tools: phone camera — Time: ten minutes
- Switch off at the breaker, open the door and sponge the standing water out of the base. — Tools: sponge, bowl — Time: fifteen minutes
- Twist out the filter assembly, rinse it under a hot tap with a brush and clear the sump by hand.
- Refit the filter until it locks, then unscrew and clear the worktop air gap if the installation has one.
Before you touch anything
Safety
Standing water may be hot and often hides glass. Isolate at the breaker, let it cool, and wear gloves in the sump. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never reach into the sump with the machine connected.
Where an owner fix ends and a service call begins
The filter, air gap and hose are all clear and water still stands in the base The pump is silent through the drain step Dirty water keeps appearing when the machine is idle after the high loop has been corrected
