Maytag MicroClean HE dishwasher error codes

Shut off power to the dishwasher for 5 minutes. If the code resumes when you restore power, replace the electronic control board.

Check all buttons on the user interface control for a response. If one or more of the buttons don't work, unplug the dishwasher to disconnect electrical power and disconnect the user interface control wire harness. Reassemble the door with the user interface wire harness disconnected, but don't close the door. Plug in the dishwasher and wait at least 7 seconds for the electronic control board to power up completely. Then close the door. If the electronic control no longer detects stuck buttons with the user interface wire harness unplugged, it will start the drain pump. If the drain pump runs, replace the user interface control. If the drain pump doesn't run, then replace the electronic control board because it still detects stuck buttons with the user interface control unplugged.

Unplug the dishwasher to disconnect electrical power and then check the wiring between the electronic control board and the thermistor/OWI sensor. Repair or replace the wire harness if broken. If you find the wiring undamaged, replace the thermistor/OWI sensor.

Unplug the dishwasher to disconnect electrical power and then check the wiring between the electronic control board and the thermistor/OWI sensor. Repair or replace the wire harness if broken. If you find the wiring undamaged, replace the thermistor/OWI sensor.

Disconnect the dishwasher drain hose connection from the air gap or the garbage disposal if you have no air gap. Pour water through the drain hose to see if water backs up into the dishwasher tub. If so, replace the portion of the drain hose that connects to the drain pump because the check valve in that hose failed. If water doesn't back up into the dishwasher through the drain hose, reconnect the hose and run the Service Diagnostics Test according to the instructions in the tech sheet. You should see low soil level indicated during the OWI test in the diagnostic mode. If you see high soil level during the OWI test, unplug the dishwasher and clean the OWI sensor. Reassemble the dishwasher and plug the dishwasher back in to restore electrical power. Run the diagnostic test cycle so the electronic control board will calibrate the OWI sensor on the next cycle. Run a normal wash cycle. If you still see the error code, replace the thermistor/OWI sensor.

Unplug the dishwasher to disconnect electrical power. Check the circulation pump wire harness and reconnect any loose wires or replace the wire harness if damaged. If the wiring connections are okay, replace the circulation pump and motor assembly. If the problem continues, replace the electronic control board.

This code appears if you don't close the door within 4 seconds of pressing the Start/Resume button, or if the door latch assembly is broken. When starting a cycle, close the door within 4 seconds after pressing Start/Resume. If you can't start the cycle and the code continues, then the door switch could be defective. Unplug the dishwasher to disconnect electrical power. Disassemble the door and check the door switch wire harness. Reconnect any loose wires or replace the wire harness if damaged. If the wire harness is okay, replace the door latch assembly.

The electronic control board expects to see the door open between cycles or the dishwasher won't start the next time you try to start a new cycle. If you didn't open the door between cycles, cancel the cycle. Open and shut the door, and then start a new cycle. If the cycle still won't start, then the door switch could be defective. Unplug the dishwasher, then plug it back in to simulate the door opening. If the cycle starts, replace the door latch assembly because the door switch isn't detecting the door opening.

Check for an item stuck under the overfill float and remove it. If the overfill float sticks in the "up" position the dishwasher won't fill. Unplug the dishwasher to disconnect electrical power and shut the water supply valve. Disconnect the water supply line from the water inlet valve and check the water inlet valve screen for clogs. Replace the water valve if you find the screen clogged because debris from the clog can get into the valve body, causing the valve to stick open and possibly flood your kitchen. If the screen is clear, place the end of the water supply line in a shallow pan and briefly open the water supply valve to see if water flows from the supply line. If water doesn't flow, have a plumber repair the water supply to your dishwasher. If the water flows okay, check the wiring connections on the water inlet valve and reconnect any loose wires or replace the wire harness if damaged. If the wires are okay, you may need to replace the water inlet valve or the electronic control board.

Unplug the dishwasher to disconnect electrical power. Remove the bottom front access panel and toe panel. Check the wire harness connections on the water inlet valve. Reconnect any loose wires. Replace the wire harness if damaged. If the wire harness connections are okay, check the resistance of the water inlet valve using a multimeter. You should measure around 1,400 ohms of resistance through the water inlet valve. If you measure infinite resistance, replace the water inlet valve. If the problem continues, replace the electronic control board.

Check for sudsy water. If you see excessive suds, try to drain the dishwasher by cancelling the cycle. The drain pump will run for 3 minutes. If the drain pump can't drain the sudsy water, drain the water by hand or use a wet/dry shop vacuum to remove the water. Check the detergent dispenser and replace if it's damaged. Use only dishwasher detergent in the dishwasher. Using regular dish soap in the dishwasher causes excessive suds. If you don't see excessive suds, check the water fill level in the tub because low water level causes air in the pump. The water level should just touch the bottom of the overfill float mushroom. If you find the water level too low, check for bowls or containers that flipped over during the cycle that could be holding water. Load items so they don't flip over during the cycle and cause low water level. If you didn't find bowls or containers flipped over and holding water, then a defective water inlet valve could cause the low water level. Unplug the dishwasher to disconnect electrical power and close the water supply valve. Disconnect the water supply line from the water inlet valve and check the water inlet valve screen for clogs. Replace the water valve if you find the screen clogged because debris from the clog can get into the valve body, causing the valve to stick open and possibly flood your kitchen. If the screen is clear, place the end of the water supply line in a shallow pan and briefly open the water supply valve to see if the water flows from the supply line. If water doesn't flow, have a plumber repair the water supply to your dishwasher. If the water flows okay, check the wiring connections on the water inlet valve and reconnect any loose wires or replace the wire harness if damaged. If the wires are okay, you may need to replace the water inlet valve.

Check for and remove any items stuck under the overfill float. , A defective water inlet valve also can cause the float switch to trip open. If the water inlet valve sticks open, the dishwasher will fill constantly causing the float switch to trip. If this happens, replace the water inlet valve because the valve is stuck open. A third cause for the error code is a defective float switch. Unplug the dishwasher to disconnect electrical power and check the resistance through the overfill float switch. You should measure near 0 ohms of resistance with the dishwasher tub empty (or near empty). If you measure infinite resistance, replace the float switch.

Unplug the dishwasher and check the wiring connections between the water softener salt sensor and flow meter. Reconnect any loose wires and repair any damaged wires. Check the wiring connections between the water softener salt sensor and electronic control board. Reconnect any loose wires and repair any broken wires. If wiring connections are okay, replace the flow meter.

Unplug the dishwasher and check the wiring connections between the electronic control board and the water softener regeneration valve. Reconnect any loose wires and repair any broken wires. Check resistance through the regeneration valve circuit through the wires that connect the valve circuit to the electronic control board using a multimeter. The meter should measure between 890 and 1,090 ohms through the regeneration valve circuit. If resistance is within that range, replace the electronic control board because the control board isn't sensing the regeneration valve circuit. If the meter measures infinite resistance, check resistance directly at the regeneration valve. If the meter measures infinite resistance directly at the regeneration valve, replace the water softener tank assembly. If the meter measures between 890 and 1,090 ohms directly at the regeneration valve, repair or replace the wire harness because a damaged wire harness is causing the meter to measure infinite resistance through the regeneration valve circuit.

Inspect the heating element and replace it if you find visible damage. If the heating element appears to be intact, unplug the dishwasher and check the wiring between the electronic control board and the heating element. Reconnect any loose wires or replace the wire harness if damaged. If the wiring is intact, replace the heating element.
