Dishwasher Not Draining? A Safe Step-by-Step Checklist

Standing water after a cycle usually points to a drainage restriction. Here is what you can safely check.

Troubleshooting

Dishwasher Not Draining? A overview

When a dishwasher will not drain, the first suspects are a clogged filter, a kinked drain hose, or a recently installed garbage disposal. Turn power off at the breaker and the water supply off before you look. If it hums with no water moving, grinds, or makes no pump sound, stop and book a diagnosis.

A dishwasher that leaves water standing in the tub throws off the whole household routine. Still, pooled water does not tell you which part has failed, so begin with observations that are safe to make, can be repeated, and will come in handy if you later book a Maytag service visit.

First checks

Start with the simple conditions

Stop the cycle if it is still running, give the water a moment to settle, then take out the accessible filter as the manual describes and rinse it. Check with the dishwasher sitting in its usual position, and never force a panel, fitting or control. When a small adjustment changes the outcome, run one normal cycle before you decide what the cause was.

A bend you can see in the reachable drain hose, or a disposer hookup added not long ago, may account for the poor drainage without any sign of a bad pump. Pay attention to when it happens: on every cycle, only with certain loads or settings, or once the machine has been going for a while. Noting that is worth more than restarting the dishwasher again and again. If water still sits in the tub after you have handled the filter and hose, quit running further drain cycles, since each attempt sends more water toward areas an owner should not reach into.

Stop & call

What does the sound of the pump say about a drain problem?

Maytag's drainage page links sound to cause. A steady hum with no water movement can mean a jammed impeller, grinding suggests hard debris such as glass at the pump, and no pump sound can point to an electrical or control issue. Remove and clean the filter, and look in the sump for labels, seeds, toothpicks, or glass. Use a soft brush, no abrasive pads.

Safe boundary

Safe checks that protect the appliance

The use-and-care manual covers controls, filter access and upkeep intervals for your particular model, so keep it handy. Limit cleaning to the parts it calls user-serviceable, stick with the cleaning products it recommends, and put each removable piece back in the position it was built to sit in.

  1. If a message or error code appears, write it down before you clear it.
  2. Inspect hoses, vents, seals and plugs you can see, leaving electrical connections where they are.
  3. Run a single controlled test instead of several attempts in quick succession.
  4. Scrape plates and let the hot tap run before starting a cycle to head off repeat clogs.

Fine to try

  • Rinse the filter
  • Look at how the visible hose runs
  • Note the error code

Hand to a technician

  • Putting a hand into the pump
  • Unplugging wiring
  • Forcing drain cycle after drain cycle

Prior to another attempt, clear whatever is in the way, lighten an unusually full load, and confirm that nothing is limiting air movement, the water supply or the door's clearance. Repeated resets are best avoided, because they can mask a fault that comes and goes and could leave water, heat or pressure in places they should not be.
