How do I fix Maytag F6E3 Error Code - 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.

Maytag F6E3 Error Code — What It Means

F6E3 is a suds or foam detection fault on Maytag dishwashers. The dishwasher has sensed excessive foam in the wash system, which interferes with normal operation and can prevent the machine from filling properly. This code appears when the wrong type of detergent has been used, too much detergent has been added, or when suds have built up from a previous load.

Common Causes

Wrong detergent type Using laundry detergent, hand soap, or hand-washing dish soap instead of automatic dishwasher detergent creates excessive suds.
Too much dishwasher detergent Overloading the dispenser cups with detergent produces more foam than the machine can handle.
Missing rinse-aid cap Forgetting to replace the rinse-aid dispenser cap after filling allows rinse aid to leak and foam during the cycle.
Residual suds from prior loads Foam left over from a previous incorrect detergent use can trigger the fault even when correct detergent is now used.
Suds detection sensor or control board fault If suds are cleared but the code returns, the sensing or control logic may have failed.

Step-by-Step Fix

Open the dishwasher and look for visible foam or suds in the tub or around the door seal.
Scoop out as much foam as possible using a plastic cup or large spoon, then wipe down the tub interior.
Remove all dishes, then add 2 to 3 tablespoons of vegetable cooking oil to the bottom of the empty dishwasher to suppress remaining suds.
Run a full cycle with no detergent and no dishes to flush the oil and remaining foam from the system.
Run a second full cycle with the correct amount of dishwasher detergent in the dispenser cups but no dishes loaded.
Check the rinse-aid dispenser cap and make sure it is securely reinstalled if you recently refilled the rinse aid.
Confirm you are using only automatic dishwasher detergent (not laundry soap, hand soap, or liquid dish soap) and reduce the dose if you have been using more than the dispenser cup holds.
If the F6E3 code returns after clearing suds, the suds detection sensor or control board may need service, since Maytag does not publish component-level diagnostics for this code.

Parts Often Needed

Part	Notes
Automatic dishwasher detergent	Amazon \| Replace any laundry or hand soap with a product labeled for automatic dishwashers only.
Rinse-aid dispenser cap	Amazon \| Order the correct cap for your Maytag model if the original is missing or damaged.

When to Call a Pro

Call a technician if the F6E3 code reappears after you have cleared all visible suds, run the two flush cycles with oil, and confirmed you are using only automatic dishwasher detergent in the correct amount. Persistent codes after suds removal usually point to a problem in the suds sensing circuit or main control board, and Maytag does not publish public diagnostics or part numbers for those components. A qualified service tech will have access to the model-specific technical sheet and can test the sensing system and replace faulty boards if needed.
