The short answer
On a GE Adora dishwasher, standing water is most often a blocked filter and sump rather than a failed pump, and the next most common cause is the drain hose or the sink waste it connects to. Both are owner-checkable. A dishwasher installed without a high loop, or connected to a waste spigot that was never opened, will never drain properly however good the machine is. The parts that run a cycle every day are the parts that fail here, and they are ordinary parts that a technician carries on the van.
What you actually observe
- It drains slowly but does get there — A partial restriction, usually grease in the hose or a full filter.
- Standing water covering the base at the end of a cycle — A drainage fault: filter, hose or pump.
- The machine has never drained properly since installation — Almost certainly a blanked waste spigot or a missing high loop.
- NEAR MISS: dishes come out gritty but the machine empties — That is a cleaning fault and belongs on the page for a dishwasher that does not clean.
The causes, most likely first on this brand
- A blocked filter and sump — Food debris, labels and broken glass collect in the sump in front of the pump, and once packed they stop water reaching the impeller at all. Ranked first on a GE Adora dishwasher: the drain path on a full-size American build is long and shallow, and it silts up quietly.
- A kinked or blocked drain hose — The hose runs through a cabinet where it is easily crushed, and grease builds inside it over years until the bore is a fraction of what it was. Ranked second on a GE Adora dishwasher: this is a high-volume platform where the hardware that cycles daily wears out long before anything exotic does.
- A missing high loop or air gap — Without the loop the hose siphons, so the machine either drains and refills from the sink or never develops the head the pump needs. Ranked third on a GE Adora dishwasher: the parts here are conventional, accessible and made to a service life, so the cheap and reachable causes genuinely do come before the expensive ones.
Check in this order, and why this order
- Lift out the filter and look into the sump beneath it — Debris packed round the sump opening explains a complete drainage failure.
- Open the cabinet and look along the whole drain hose run — A crushed section behind a base unit is common after any plumbing work.
- Look at whether the hose rises high inside the cabinet before falling to the waste — A hose running flat from machine to waste is the installation fault behind many of these calls.
What an owner can safely check
- Remove the filter assembly and clear the sump by hand and with a cup — Work carefully: broken glass collects here and is very hard to see under water.
Tools: cup, gloves, towelsAbout 30 min
- Trace the hose from the machine to the waste, freeing any kink — Where it joins the sink waste is where grease builds thickest.
Tools: torchAbout 25 min
- STOP HERE once the filter, sump, hose and waste are all proven clear — Pump access means removing panels and working at live terminals.
Before you open anything
Safety
Switch off the breaker before removing any panel or working under the machine, and be careful in the sump: broken glass collects there and is invisible under water. Use gloves. Never mix dishwasher detergent with bleach or any other product, and be aware that water standing in the base after a cycle can still be hot enough to scald.
When to call a technician
Call once the filter and sump are clear, the hose is free and looped, and the waste connection is proven open, and water still stands in the base — that points at the pump or the control that drives it. Call a plumber instead if the sink waste itself backs up, because the fault is in the plumbing rather than the appliance.

What this page does not cover
This page covers the GE Adora dishwasher as a class, not one family or model line. Part numbers, wiring colours, torque figures and panel fixings differ from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, that page is the more specific answer and should be read first.
