Dishwashers

Dishwasher drains partially but leaves some water

A small amount of water (roughly a cup) remaining around the drain area at the bottom is often normal and there to keep the pump seal from drying out; a larger puddle across the whole tub floor is not.

Symptoms

  • A small pool of water sits directly around the drain/filter area
  • Rest of the tub floor is dry
  • No unusual smell or debris in the water
  • Amount of water stays consistent cycle to cycle

Likely causes

  • CommonNormal reserve water by designMany dishwashers intentionally leave a small amount of water around the pump to keep seals from drying out.
  • PossibleSlightly clogged filter reducing full drainageA partially clogged filter can leave more water than the small designed amount.
  • PossibleMinor drain hose restrictionA partial kink can slow draining without stopping it completely.

What to do

  1. Check whether the water is a small amount confined to the drain area versus covering the whole tub floor.
  2. If it's a small, consistent amount in the same spot each time, this is likely normal and no action is needed.
  3. Remove and clean the filter thoroughly to rule out a partial clog contributing extra water.
  4. Check the drain hose for any partial kinks along its length.
  5. Compare the amount to your owner's manual, which sometimes states an expected small residual amount.
  6. If the amount is clearly larger than a small puddle or keeps growing, treat it as a full drainage problem and check the filter, hose, and pump.

When to call a pro

If the water amount is more than a small residual puddle, follow the steps for a full drain failure and consult a technician if it persists.
