You can try multiple fixes to get your Amana dishwasher up and draining again! Here’s what you need to know about how to fix an Amana dishwasher that is not draining properly.

Why has the Amana dishwasher stopped draining water?

why is my Amana dishwasher not draining

There are many reasons why your Amana dishwasher stopped draining water. The most possible cause is kinked, collapsed, or obstructed hose. If the hose gets clogged, it will prevent water from draining correctly.

Another possible reason is a damaged or defective pump. If the pump isn’t working, the water can’t be properly pumped out of the dishwasher. A malfunctioning drain line could also create this draining issue. Because If the line is blocked or clogged with food particles or other garbage, the water can’t flow out of the dishwasher.

However, these are the most common reasons you are facing water draining issues in your Amana Dishwasher:

  • The dishwasher’s drain hose may be kinked, preventing water from flowing through it
  • Something is blocking the drain hose.
  • The dishwasher’s drain pump may be damaged.
  • The water inlet valve may not be working.

How to fix the Amana dishwasher water drainage issue.

In Short: To fix the drainage issue in your Amana Dishwasher, check the drain hose to ensure it is not clogged. Clear the hose with a plunger or a plumbers snake if the hose is clogged. If the hose is not clogged, the next thing to check is the drain screen and filter, and make sure they are not clogged with any food particles.

Step 1: Check the Garbage Disposal

A garbage disposal device is usually electrically powered and installed under a kitchen sink between the drain and the trap. The disposal grinds food waste into small pieces flushed away through the municipal sewer system.

Sometimes it becomes clogged with food buildup and can reduce the water flow. Chances are that your device is also having this issue, and that’s why it can’t flow water properly. Run the disposer thoroughly with plenty of water running to clear it out. This may fix the drainage problem with the dishwasher.

Step 2: Unclog the Air Gap

The air gap is a small plastic or metal fitting installed on the top of the sink near the faucet. It has a small hole in the top that water can come out of. The air gap prevents water from being siphoned back into the dishwasher. If water leaks from the air gap when the dishwasher is running (and occasionally, this water winds up all over the counter), there is a blockage between the air gap and the garbage disposal.

To unclog the air gap, simply remove the cap and clear the hole with a small wire or a toothpick. Next, ensure the hose that runs from the nipple at the bottom of the air gap to the garbage disposal or sink drain is not clogged. You can watch this video if you still can’t unclog it.

Step 3: Check the Drain Screen

The drain screen of a dishwasher is there to catch food particles and other debris that could clog the dishwasher’s drain. Over time, the screen can become clogged with debris, making it difficult for water to drain from the dishwasher.

Check and make sure nothing is clogging the drain screen at the bottom of the dishwasher tub. Clear trash away from the drain screen and ensure it is free of blockage.

Step 4: Clean the Filter

Large food particles are filtered out by a dishwasher filter, which prevents them from blocking the drain pump or hose. The filter might fill up with debris over time, preventing water from draining. When your Amana dishwasher doesn’t drain, cleaning the filter could be a simple solution.

Amana dishwasher filter system consists of 2 parts, an upper filter assembly, and a lower filter. You have to clean both of them. To clean the filter in your Amana dishwasher, follow the below steps:

  • First, turn the upper filter assembly counterclockwise and lift it out.
  • Then grasp the Lower Filter in the circular opening, lift slightly, and pull forward to remove.
  • Clean the filters by rinsing them under running water until most soils are removed.
  • Reinstall the lower filter by placing it under the locating tabs at the bottom of the dishwasher.
  • Finally, insert the upper filter assembly and slowly turn it clockwise, so it locks into place.

Do not use any wire brush, scouring pad, etc., to clean the filter assembly, as they may damage the filters. Instead, only use a soft brush.

Step-5: Unclog the drain Hose

The drain hose is a thin, plastic tube that links the dishwasher to the sink drain or debris disposal, allowing water to drain. When it’s clogged by debris, it usually loops under the sink and can kink, blocking water flow.

Although a professional can unclog the hose, a skilled DIYer might be able to do it. To remove drain hose blockages, follow the below steps:

  • First, unplug the dishwasher.
  • Then identify the drain hose by checking your Amana dishwasher manual. The majority of them are hidden beneath a lower front panel.
  • After you locate it, disconnect the drain hose from the pump.
  • Now, observe the hose for any blockages and use a screwdriver or a straightened wire hanger to remove any obstructions.

If you can’t reach the clog, disconnect the hose from the sink drain or disposal and try again. But if you still can’t unclog it or it is damaged, replace it with a new one.

1. Nothing worked! What next?

If you have tried all of the solutions mentioned above and your Amana dishwasher is still not draining water, several dishwasher parts could be at fault. Most dishwasher replacement parts are widely available online.

But you may be unable to check and change those parts (like Valve, Pump solenoid, Piston and nut assembly, Timer, Door switch, or drain motor) yourself as you are not experienced enough. It is best to call a qualified repairer to look at your machine.

2. Should I run my dishwasher if it has standing water?

No, Whatever the cause, standing water can harm your dishes and dishwasher, and you shouldn’t run your dishwasher if it has standing water. If you leave this untreated for an extended period, the water may develop dangerous bacteria, and dishwasher parts may corrode or become water-logged.

3. Should the dishwasher still have water in the bottom?

Everything is normal if there are no more than two cups of water in your dishwasher after a cycle. Typically, the appliance remains wet after a cycle due to the condensation drying principle, which causes water droplets in the tub – which are actually desirable in this case.
