Opening the dishwasher and finding dirty water in the bottom can be frustrating. The dishes may still be wet or covered with residue, and the appliance may produce an unpleasant odor after sitting between cycles.
A small amount of clean water near the filter may be normal for certain dishwasher models. A larger pool of cloudy or dirty water usually indicates that the dishwasher did not complete the drain process correctly.
For homeowners in Loveland and surrounding Northern Colorado communities, the problem may be as simple as a dirty filter. It may also involve a blocked hose, a plumbing connection, a drain pump, or an electrical component.
Signs Your Dishwasher Is Not Draining Correctly
Standing water is the most obvious warning sign, but it is not the only one. You may also notice:
- Water remaining after the cycle ends
- Food particles collecting around the filter
- Dishes that feel greasy or gritty
- Gurgling sounds from the sink or disposal
- Water returning to the dishwasher after draining
- A persistent musty or sour odor
- An error code on the control panel
- Water leaking from the door during a cycle
Stop using the dishwasher if water is leaking onto the floor. Continued operation may damage cabinets, flooring, or nearby electrical connections.
Common Reasons a Dishwasher Will Not Drain
1. The Dishwasher Filter Is Clogged. Many newer dishwashers have a removable filter near the bottom of the tub. When the filter becomes clogged, water may move slowly or remain in the dishwasher after the cycle.
2. Debris Is Blocking the Sump Area. The sump is the recessed area beneath or near the filter where water collects before being pumped out. Small pieces of glass, food labels, bones, and seeds can collect in this area.
3. The Drain Hose Is Kinked or Blocked. The dishwasher drain hose carries wastewater to the garbage disposal or household drain connection. A recently moved or installed dishwasher is especially likely to have a bent or incorrectly routed hose.
4. The Garbage Disposal Connection Is Blocked. Many dishwashers drain through a connection on the garbage disposal. Food buildup in the disposal or sink plumbing may prevent the dishwasher from emptying. A newly installed disposal has a knockout plug at the dishwasher connection — if that plug was not removed, dishwasher water cannot enter the disposal.
5. The Sink Drain or Air Gap Is Clogged. Some kitchens have a dishwasher air gap mounted near the faucet. Food residue can collect inside the air gap and interfere with drainage.
6. The Drain Pump Is Jammed or Failing. The drain pump pushes water out of the dishwasher. A humming sound without drainage may indicate that the pump is trying to operate but cannot move water.
7. The Control System Is Not Completing the Cycle. A faulty door latch, timer, sensor, control board, or wiring connection may prevent the dishwasher from reaching or completing the drain portion of its cycle.
Safe Checks to Try Before Scheduling Repair
- Cancel the current cycle and select the dishwasher's drain function
- Run the garbage disposal if it is working normally
- Confirm that the kitchen sink drains freely
- Turn off power to the dishwasher
- Remove and clean the filter according to the owner's manual
- Check the visible sump area for food or debris
- Inspect the accessible portion of the drain hose under the sink
- Look for a blocked air gap, when one is installed
Do not pour chemical drain cleaner into the dishwasher. These products may damage internal components and create a chemical exposure risk when a technician opens the drain system.
When to Call for Dishwasher Repair
Schedule dishwasher repair in Loveland when the filter is clean but water remains, the drain hose is blocked, the drain pump hums or grinds, water leaks beneath the dishwasher, or dirty water flows back into the tub.
