Maytag Dishwasher 100% Fix Troubleshooting Guide

Dishwashers are one of the most used appliances in the kitchen. They save us time and make cleaning up after meals so much easier. However, when your dishwasher stops working properly, it can be incredibly frustrating. As one of the leading appliance brands, Maytag dishwashers are known for their reliability and performance. But like any appliance, problems can develop over time.

This troubleshooting guide will help you diagnose and fix common Maytag dishwasher issues. We'll cover troubleshooting codes, control panel issues, water supply problems, draining failures, and maintenance tips. With a few simple checks and repairs, you can get your Maytag dishwasher back to working order.

Maytag Dishwasher Troubleshooting Control Panel

The control panel is the brains of your Maytag dishwasher. Any issue with the control panel can prevent your dishwasher from running or operating normally. Here are some common control panel problems and how to troubleshoot them:

  1. Display or lights not working: If the display or indicator lights won't illuminate, it likely indicates an electrical problem. Check the circuit breaker and make sure the dishwasher is getting power. Test for a bad control panel by pressing buttons to see if it responds.
  2. Control buttons not responding: Sticky or jammed buttons could be the culprit if the control panel seems unresponsive. Try pressing the buttons firmly to release them. If the buttons are broken, the membrane switch board might need replacing.
  3. Cycle not starting: When the cycle won't start after you've pressed Start, it could mean the control board is defective. Try rebooting the dishwasher and rerun the cycle. If the issue persists, you may need to replace the main electronic control board.
  4. Beeping noises: Strange beeping from your dishwasher's control panel could signal an error code. Refer to the owner's manual to identify the specific fault code and take corrective action. Common causes include water leaks and heating issues.

Following troubleshooting steps in your owner's manual can help diagnose many control panel issues. But if problems persist, getting professional service may be needed to replace faulty parts like the membrane switch board or main electronic control board.

Maytag Dishwasher Troubleshooting Codes

Maytag dishwashers have built-in diagnostic systems that display fault codes when a problem is detected. These error codes appear on your dishwasher's display screen or control panel. Understanding what these codes mean is crucial for troubleshooting issues.

Here are some of the common Maytag dishwasher error codes and what they indicate:

F1 code:
The dishwasher has detected a long fill issue. This could be from low water pressure, a faulty water inlet valve, or a clogged screen.
F3 code:
This code indicates a draining failure. Check for kinks in the drain hose, food clogs in the drain filter or pump, or an issue with the drain pump.
F5 code:
A F5 code signifies that the dishwasher has not reached the proper water temperature. The heating element or thermistor sensor may need replacement.
F7 code:
A leak has been detected. Inspect door seals, hoses, and fittings around the dishwasher for any water leaks. The leak sensor might also need replacement.
F8 code:
This points to a motor speed error. The circulation pump motor, main control board, or wiring harness likely needs servicing.
F20 code:
With this code, the dishwasher has detected an issue with the wash pump system. Check the pump filter and impeller for blockages. The wash motor might need to be replaced.

Consult your Maytag dishwasher manual and model-specific repair guides to further diagnose the error codes. Getting the precise fault code is essential to pinpoint the failed part. With the code, you can order the correct replacement part to resolve the problem.

Maytag Dishwasher Troubleshooting No Water

If your Maytag dishwasher won't fill with water, there are several possible causes to check:

  1. Clogged water inlet valve: Mineral deposits and debris often build up on the dishwasher's inlet valve screen. Disconnect the water line and clean the screen using vinegar or lemon juice and a toothbrush.
  2. Defective float switch: The float switch prevents overfilling by shutting off the water when it reaches a certain level. If defective, it won't stop the water at the right time. Replace the float switch.
  3. Kinked supply line: Check that the water supply line is not kinked or crushed behind the dishwasher. Straighten or replace the line if necessary.
  4. No power to inlet valve: If you hear buzzing or humming but no water enters, power may be out to the inlet valve. Ensure the valve is getting voltage and replace the valve if faulty.
  5. Low water pressure: Water pressure below 20 psi can trigger a no-fill situation. Have your home's water pressure tested and use a water pressure booster if needed.
  6. Bad control board: The main control board regulates power to the inlet valve. If burnt out or defective, no voltage reaches the valve. Replace the main control board.

Start troubleshooting with easier DIY checks, like inspecting the water line and float switch. Call in professional service if needed to test electrical parts and replace defective valves or control boards.

How to Fix Maytag Dishwasher Not Draining

If your Maytag dishwasher won't drain properly, leaving standing water in the tub, there could be a few causes:

  1. Clogged or kinked drain hose: Food particles or debris can block the drain hose. Disconnect from the sink drain and clean out the hose. Also straighten any kinks in the hose.
  2. Weak drain pump: A worn-out drain pump impeller or motor won't effectively push water out. Replace the dishwasher drain pump if faulty.
  3. Clogged filter or sump: Check the drain filter and sump for trapped food or grease buildup. Clean and clear out the filter assembly.
  4. Jammed float switch: The float switch sticks up to stop draining when water remains in the tub. Carefully pry up a stuck float switch. Replace it if damaged.
  5. Pinched impeller: If something falls into the tub, it can jam between the impeller and pump housing. Unjam the debris and spin the impeller to confirm it rotates freely.
  6. Bad check valve: A failed check valve allows water to flow back into the dishwasher. Replace the check valve kit or pump assembly if faulty.

For sluggish draining, start by inspecting the drain hose and filter for clogs. But for a dishwasher that won't drain at all, pump parts or electrical issues are more likely the problem. Professional service may be required to replace the drain pump, check valve, or float switch.

How to Reset a Maytag Dishwasher

Resetting your Maytag dishwasher can help resolve issues with sticking buttons, error codes, unusual sounds, or other glitches. To reset a Maytag dishwasher:

  1. Turn off power to the dishwasher at the circuit breaker. Leave it off for 30 seconds.
  2. Turn the breaker back on to restore power.
  3. Press the "Start/Reset" button on the dishwasher's control panel.
  4. Wait for the control panel lights to turn off. They should illuminate again when reset is complete.
  5. Press Start to begin a test cycle and confirm normal operation. If problems persist, repeat the reboot process.

Power cycling the dishwasher essentially reboots the control board and electronically controlled parts. It can clear software glitches or overload issues. Just taking power off briefly then restoring it often helps electrical components reset.

If your Maytag dishwasher lights are flashing error codes, be sure to note the code before resetting. Check the owner's manual to identify the specific error so you can address the problem. Resetting first may cause the error code to clear which can prevent troubleshooting.

How to Clean a Maytag Dishwasher Filter

Regular cleaning of your Maytag dishwasher filter prevents debris buildup that can clog pumps and spray arms. You should clean the filter every few months for optimal performance. Here's how:

  1. Locate the filter in the bottom of the dishwasher tub. It has a handle or tab for easy removal.
  2. Twisting the filter counter-clockwise, pull it up and out. Rinse under warm water to remove food particles.
  3. Use a sponge or brush to clean the inner filter screen mesh until all residue is gone.
  4. Check and clean the filter housing, removing any built-up debris.
  5. Reseat the filter, turning clockwise to lock into place.
  6. Confirm the filter assembly is fully sealed within the tub bottom before running a cycle.
  7. Run an empty wash cycle to flush out any remaining debris.

Take extra time cleaning the filter screen mesh and inner housing. If grease builds up, use hot soapy water or an all-purpose cleaner.

Cleaning the Filter Parts and Components

For periodic deep cleaning, soak the filter in white vinegar or citric acid cleaner to dissolve hard water and mineral deposits. Rinsing thoroughly, check that the filter screen moves freely within the housing. Replace any badly bent or corroded filter parts.

Cleaning the dishwasher filter regularly prevents costly repairs down the line. A clogged filter can overload the pump, cause noisy operation, and lead to flooding issues. Just a few minutes every month keeps your Maytag dishwasher filter clean for peak washing performance.
