What does Maytag Dishwasher F8E5 Error - Causes & Fix mean?

F8E5 means your Maytag dishwasher detected overfill or the fill valve is stuck open. Turn off the water supply, then replace the valve.

How do I fix Maytag Dishwasher F8E5 Error - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Maytag Dishwasher F8E5 Error - Causes & Fix?

The most frequently replaced parts for Maytag Dishwasher F8E5 Error - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Maytag Dishwasher F8E5 Error - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Maytag Dishwasher F8E5 Error — What It Means

The F8E5 error code on a Maytag dishwasher signals a fill or overfill fault. The machine has detected a water-level condition that indicates overfilling or a fill valve that is admitting water when it should not be. When this code appears, the dishwasher will immediately start a drain sequence and block normal operation to prevent flooding. Maytag’s own service guidance tells you to turn off the water supply to the dishwasher if possible, turn off power only if the water cannot be shut off, and press Cancel to silence the alarm.

This code is an overfill or unintended-fill protection event, not a general leak code. The technical manual links F8E5 specifically to a fill valve that is mechanically stuck open. It can also appear if the control board is not removing power from the valve when it should or if the float or overfill sensor detects abnormal water in the sump or base pan area.

Common Causes

Water inlet valve stuck open or leaking through The fill valve is mechanically jammed or its internal seal has failed, allowing water to pass even when the valve should be closed.
Control board not de-energizing the valve The control board or wiring harness is leaving power applied to the fill valve when the dishwasher is not supposed to be filling.
Obstructed or stuck float switch or overfill sensor The float assembly or overfill-sensing path in the sump is blocked, stuck, or contaminated, causing a false overfill reading.
Actual leak into the base pan or sump area Water from a hose leak, drain connection leak, or under-sink plumbing issue has entered the base pan and triggered the overfill protection.
Harness or wiring fault to the valve Damaged wires or connectors in the fill-valve circuit prevent the control from properly opening and closing the valve.

Step-by-Step Fix

Turn off the water supply to the dishwasher first, then press Cancel to silence the alarm. Only turn off power if you cannot shut off the water supply, and keep the door closed until the unit is safe.
Check whether the dishwasher is actively filling when it should not be. Open the door and listen for water flowing into the tub or sump. If you hear continuous filling, suspect the inlet valve or control circuit.
Inspect the base pan and sump area for standing water or leaks. Pull the dishwasher forward and look for water under the unit, check hose connections at the inlet valve and drain, and inspect the tub-to-pump seal and door gasket for leaks.
Locate and inspect the float or overfill sensor in the sump at the bottom of the tub. Remove any debris, food particles, or buildup that might hold the float up or obstruct the sensor, then verify the float moves freely up and down.
Test the fill valve electrically and mechanically. Disconnect power and water, remove the inlet valve, and check whether water drips through when the valve is not energized. If it leaks or sticks open, replace the valve. If the valve is dry, check the harness and control board output for correct operation.
Clear the fault and run a test cycle after the repair. Restore water and power, press Cancel to clear F8E5, then start a rinse or test cycle and monitor the fill process to confirm the valve opens and closes correctly and the code does not return.
Check for additional fault codes stored in the control. Maytag’s technical guidance advises checking whether F8E5 is logged alongside other codes, which can help pinpoint control board or harness issues rather than a simple valve fault.

Parts Often Needed

Part	Notes
Water inlet valve assembly	Amazon \| Match your model number. Replace if mechanically stuck, leaking through, or passing water when de-energized.
Float switch or overfill sensor	Amazon \| Order the correct sump float assembly if the float is cracked, stuck, or the switch contacts are faulty.
Main control board (ACU)	Amazon \| Replace only if you have verified the valve and harness are good but the control is leaving the valve energized incorrectly.

When to Call a Pro

Call a technician if you cannot safely access the water supply shut-off, if the dishwasher continues to fill after you have replaced the inlet valve, or if you find water in the base pan but cannot locate the source of the leak. Also call for help if the F8E5 code returns after you have cleared it and verified the valve and float are working correctly, or if you see multiple fault codes stored in the control that suggest a board or wiring problem. Electrical diagnostics on the control board and tracing harness faults require a multimeter and a wiring diagram for your specific model.
