Maytag Dishwasher Error Code F6-E3

F6-E3 indicates that the dishwasher's control has detected suds or air in the wash pump. This can be caused by excessive sudsing from improper detergent, water captured by improperly loaded items, a leaking rinse aid dispenser, a faulty overfill switch, or a drain hose check valve that is not sealing properly. The pump requires a steady water supply to operate correctly, and foam or air pockets disrupt that flow.

A reset may temporarily clear the code, but it will return if the underlying cause is not resolved. If excessive detergent suds were the cause, the suds need to dissipate first, which may require running a rinse cycle without detergent. For mechanical causes like a stuck overfill switch or a failed check valve, a reset alone will not prevent the fault from recurring.

If the fix involves only switching to the correct detergent or reloading dishes, there is no parts cost. If a component like the drain hose check valve or overfill float switch needs replacement, parts typically range from around 10 to 50 dollars depending on the specific part. Adding professional labor for diagnosis and installation can bring the total repair cost to somewhere in the range of 100 to 250 dollars.

Start by allowing the dishwasher to run for one minute, then open the door and check for visible suds. If suds are present, switch to a proper dishwasher detergent and use the recommended amount. If no suds are visible, inspect the rinse aid dispenser for leaks, check that dishes are not trapping water, and examine the drain hose check valve and overfill float switch for faults.

It is best to address the fault before running full cycles. If the pump is pulling in air rather than water, it can overheat or wear prematurely over time. If the cause is a malfunctioning overfill switch, there is also a small risk the control could misread water levels. Diagnosing the root cause first protects the pump and other components.
