Three installation faults account for most of these calls

A large share of West Hollywood apartments were built without a dishwasher. The machine in the kitchen was added during a remodel, fitted into a cabinet that was cut to size, with a drain line tied into existing sink plumbing years after the building went up.

That history explains more standing-water calls than any failed component does. Three specific things go wrong, and all three imitate a dead drain pump.

1. Missing high loop

The drain hose is supposed to rise to just under the countertop before dropping to the disposal or standpipe. That loop prevents water siphoning back into the machine after the pump has finished. On retrofitted installations this step gets skipped regularly, and the result is water in the bottom at the end of every cycle.

2. Disposal knockout plug never removed

New garbage disposals ship with a sealed dishwasher inlet. If the installer connected the hose without punching out that plug, the dishwasher has nowhere to drain at all. It is worth checking before calling anyone: disconnect the hose at the disposal and see whether the port is open.

3. Restriction downstream

The dishwasher drains into plumbing shared with the sink. If that line is partially blocked, the machine drains slowly or backs up while the pump is perfectly healthy. Run the sink and watch how quickly it clears — a slow sink drain is the clue.

What you can check in five minutes

Open the door and remove the standing water with a cup and a towel. Then pull the filter at the base of the tub — on most machines it twists out by hand — and check for food debris, glass fragments and labels from jars. Many people do not know the filter exists and have never cleaned it.

Underneath is the sump and the drain port. If you can see debris there, clear it.

Then run the disposal for thirty seconds and start a rinse cycle. If the water clears, the problem was the drain path.

When it is actually the machine

If the drain path is clear and water still stands, the suspects are the drain pump, the check valve and the control board.

A pump that hums without moving water usually has an obstruction in the impeller. A pump that is silent has failed electrically. A check valve stuck open lets water flow back in, which produces a smaller amount of standing water than a full failure — usually an inch or so at the bottom.

Integrated and panel-ready units

Kitchens here are small, so compact 18-inch machines and panel-ready dishwashers fitted flush with cabinetry are common. Both have to come forward on their own feet without catching the panel or the toe kick, and clearances are usually tight. We check that before disconnecting anything and protect the floor and cabinet faces first.

If water is also on the floor

Standing water inside the machine is a drain problem. Water on the floor is a leak, and in a stacked building it reaches the unit below. Shut off the supply valve under the sink and stop running the machine until the source is found.

What the visit covers

The $89 diagnostic covers the trip and a full inspection: drain hose routing and high loop, disposal connection, sink drain, filter, sump, drain pump and impeller, check valve, and control board. You get an explanation of what failed and a clear estimate before work starts. If you approve the repair, the diagnostic fee is waived, and completed work carries a 90-day warranty on labor and parts.

Frequently asked questions

Is standing water in a dishwasher normal?

A small amount in the sump area is normal on some models and keeps seals from drying out. Water covering the bottom of the tub after a completed cycle is not.

Can I use the sink while the dishwasher is broken?

Yes, unless the sink is also draining slowly, which points at a shared blockage. In that case both need clearing.

Why does it drain sometimes and not others?

Intermittent draining usually means a partial restriction rather than a failed pump — debris that moves and settles, or a hose with a low spot holding water. It tends to get worse rather than resolve.

How long does this repair usually take?

If the fault is in the drain path, often under an hour with no parts. A drain pump replacement takes longer and depends on how the unit is installed.
