The short answer
On an Element dishwasher that is leaving water in the bottom, the cause to suspect first is disposer or shared branch blocked, with filter and sump packed with debris behind it. The ranking below is written for the disposer-connected build, which you can confirm in seconds: look under the sink: a drain hose entering the side of a food disposer means the machine drains through it. The filter, the hose, the air gap and the disposer inlet are owner work; the pump under the sump is not.
What you observe
- A hum at the end of the cycle with no water moving — A powered pump that cannot turn, which is a jam rather than a failure.
- The sink drains slowly as well — A shared blockage downstream, which is plumbing rather than appliance.
- Standing water in the sump at the end of every cycle — The defining symptom, and it says nothing yet about where the blockage is.
- It started right after a new disposer was fitted — The knockout plug, until proven otherwise.
- The tub empties and then refills — Siphoning back, which is the loop or the non-return valve.
- NEAR MISS — water on the floor rather than in the tub — That is a leak, and the leak page is the one to read instead.
Causes, most likely first on this brand
- Disposer or shared branch blocked — Ranked first here: it ranks first on a disposer-connected machine because the shared branch is the part of the system the machine has no control over.
- Filter and sump packed with debris — Second: the pump can only move what reaches it. A filter matted with paper labels, seeds and fat leaves standing water in a machine whose pump is perfectly healthy.
- Drain pump impeller jammed — Third: it ranks here because the sound is diagnostic: a hum with no water movement is a jam, and silence is usually something upstream of the pump.
- Cycle interrupted before the drain step — Fourth: it belongs on the list because running a drain-only or rinse cycle settles it in minutes and saves a wasted call.
- Non-return valve stuck — Fifth: it is placed low because it is less common than everything above and sits in the same area as the pump.
- Drain hose kinked behind the machine — Sixth: the hose is soft and the machine gets pushed back against it, usually by whoever last cleaned the floor.
Check in this order, and why
- Run the sink and see whether it drains freely — A slow sink and a wet dishwasher share one blockage.
- Lift the filter out and clear the sump by hand — The one that needs no tools.
- Listen at the end of a cycle for a hum with no water moving — A hum means the pump is powered and jammed rather than dead.
What an owner can safely check
- Lift the filter and clear the sump by hand — No tools are needed.
About 15 min
- Pull the machine forward and follow the drain hose. Get a second person before you pull the cabinet out or tilt it. — Kinks behind the cabinet are common and date the fault precisely.
About 20 min
- Run a drain-only or short rinse programme — Rules out an interrupted cycle before anything is dismantled.
About 20 min
- Bail the standing water out with a cup and a sponge — Everything else is easier with a dry sump, and it takes only a few minutes.
Tools: cup, spongeAbout 15 min
- STOP HERE if the pump hums and nothing moves — A jammed impeller sits under the sump and that work is not owner work.
Before you open anything
Safety
Power off at the spur, water off at the valve, then open anything. Those two come first because the wiring and the plumbing in this cabinet run alongside each other. Leave the door latch alone: defeating it lets a hot cycle run with the door open. Bail the water out before you tip the machine forward, and treat anything in the sump as sharp until you have seen it. Get a second person before you pull the cabinet out or tilt it.
When to call a technician
Bring someone in once the free checks are clean, and sooner if the sink drains slowly too — that is a plumbing job rather than an appliance one, and a drain engineer will fix it faster than an appliance technician.

What this page does not cover
Written for Element dishwashers as a class, not for one family. No family-specific page for this brand and appliance is published here yet; where one exists for your unit it takes precedence over this page. Wiring colours, torque figures and part numbers are deliberately not here: they differ by family.
