Why Standing Water Happens
Dishwashers drain through a filter (which catches food debris), then through a hose to the drain pump, which pushes water out. A blockage anywhere in this path leaves water sitting at the bottom after a cycle finishes — and unlike a washing machine, dishwashers process food particles constantly, so their filters need more regular attention.
Common Causes
Blocked Filter
Food debris accumulates here over time — this is the single most common cause by far.
Kinked or Blocked Drain Hose
The hose behind the unit can bend or collect debris over time.
Garbage Disposal Connection Blocked
If connected to a garbage disposal or sink drain, a clog there backs up into the dishwasher too.
Faulty Drain Pump
Less common — the pump motor itself can fail or get jammed by a foreign object.
Air Gap Blockage
If your installation has an air gap (small cylinder near the sink), it can clog and prevent proper draining.
What to Check First
The filter is usually at the bottom of the dishwasher tub, under the lower spray arm, and twists out for cleaning in most models:
- Remove the filter and rinse away any trapped food debris
- Check the drain hose (if accessible) for visible kinks
- If connected near a kitchen sink, check that the sink drain itself isn't clogged
If the dishwasher still isn't draining after clearing the filter, the blockage is likely further down — that's when a proper inspection is worth it rather than guessing further.

Is This Covered Under Warranty?
If your dishwasher is still under company warranty, this is typically covered. If the warranty has expired, an independent repair with genuine parts is usually fast — filter and hose issues are inexpensive fixes in most cases.
