What this usually means
On a GE Cafe 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. Built-in installation is the hidden variable here: the same part that is a ten-minute job in a freestanding machine sits behind a trim panel and a tight clearance.
The symptoms, and the ones that mean something else
- Dirty water appears in the base from the sink — Siphoning back from the waste because the hose has no loop.
- 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.
- 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.
What it usually is, in order of likelihood
- 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 Cafe dishwasher: built-in installation changes the ranking more than the brand does, because access and clearance decide what fails and what merely looks failed.
- 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 Cafe dishwasher: the installation is part of the appliance on this tier, so where it sits decides as much as what it is.
- A blanked or blocked sink waste spigot — New sink traps come with the dishwasher spigot sealed by a moulded plug, and a machine connected to an unopened spigot cannot drain a drop. Ranked third on a GE Cafe dishwasher: supply lines on a built-in run through cabinetry and are the part of the installation nobody can see to check.
The order to work in, and the reason for it
- 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.
- Check whether the machine has ever drained properly since installation — A machine that never drained from day one is an installation fault, not a failure.
Owner-side checks, step by step
- 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.

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 this becomes a service call
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.

The limits of this page
This page covers the GE Cafe 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.
