The short answer
The brand lists the potential cause of F10E4 as a diverter valve error. The diverter is the valve under the lower spray arm that sends wash water to the lower arm, the upper arm, or each in turn; when the control cannot confirm where it is, it stops the cycle. A reset and a clean filter are the owner checks, and a code that returns needs the diverter tested.
Error codes
Reference| Code | Meaning |
|---|---|
| F10E4 | Potential Cause: Diverter Valve Error |
What the dishwasher does with the code showing
- Dishes on one rack come out dirty — Water is reaching only one spray arm, because the diverter is stuck in one position.
- The cycle stops early and shows the code — The control halts the wash when the diverter fails its position check.
- NEAR MISS: water under the dishwasher — A leak at the diverter has its own reading in this list; mop up and check the base before another cycle.
Likely causes, in order
- Diverter motor failed — The most common cause once a reset has been tried: the small motor that turns the diverter wears out or stalls, and the control never sees the position it asked for.
- Debris jamming the diverter — Second: debris lodged in the diverter, usually after a filter was left out, cracked or not cleaned for a long time.
- Position switch or sensor fault — Third: the switch that reports the diverter position fails, so a diverter that moves still reads as stuck.
- Wiring or connector at the diverter — Fourth: a corroded or loose connector under the tub.
- Control board — Least likely: the board fails to drive the motor or read the switch, considered only after the diverter tests good.
Where to start, and what comes next
- Reset the dishwasher — Breaker off or unplug for a minute; a code that stays away was a passing error.
- Remove and clean the filter — A clogged or damaged filter lets debris reach the diverter below it.
- Look into the sump — With the filter out and gloves on, check for glass or debris around the opening.
What you can safely do
- Reset — Switch off the breaker, or unplug the dishwasher, for a minute, then restore power.
About 2 min
- Clean the filter — Lift out the filter at the bottom of the tub, rinse it under the tap, and refit it until it locks.
Tools: soft brushAbout 10 min
- STOP before removing the lower panel or the pump — The diverter and its motor sit under the tub beside live wiring; replacing them is technician work.
Power off before any panel
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close the water supply valve, usually under the sink, before touching hoses or the inlet valve.
The point to call
Call when the code returns after a reset and a clean filter, or when one rack keeps coming out dirty. The diverter motor and its switch sit under the tub, and reaching them means pulling the dishwasher or removing the pump assembly with the power and water off.

Which models this reading covers
Generalized information for Amana dishwashers with an electronic control that reports codes in this form. It is not a reading for Amana dishwashers with dial-only controls, which flash lights rather than codes, or sister brands on the same platform, whose lists can read differently. The details that change inside the line, such as wiring colours, part numbers and connector locations, belong on model pages, and none is published for F10E4 yet. The brand gives this reading to more than one code in its dishwasher list and does not publish what separates them; which one appears depends on the model’s control, so quote the exact code when booking.
