F4E2 in brief
The brand lists the potential cause of F4E2 as the heating system: the element in the tub floor that heats the wash water and dries the dishes, and the parts that switch and protect it. Dishes may come out cool or wet, and cycles may run long; reset once, run the hot tap at the sink before a cycle, and book a technician if the code returns.
Error codes

|---|---|
| F4E2 | Potential Cause: Heating System |
Signs that go with the code
- Dishes are wet at the end of the cycle — Without heat from the element, drying depends on rinse aid and residual warmth alone.
- Cycles run much longer than usual — The control waits for water temperature that never arrives.
- Dishes feel cool when the cycle ends — The wash water was never heated.
- NEAR MISS: only plastic items stay wet — Plastic does not hold heat, so it often stays wet in a working dishwasher.
Causes, most likely first
- Heating element open or burnt — The most common cause: the element in the tub floor burns through, often with a visible blister or break, and stops heating entirely.
- High-limit thermostat or thermal fuse tripped — Second: the safety parts that cut power to the element if it overheats open and stay open, which stops heating until they are replaced.
- Element wiring or terminals — Third: the terminals under the tub corrode or loosen in the damp, hot space and break the circuit.
- Heater relay on the control — Least likely: the control fails to switch the element on, considered only after the element and its protection test good.
The order to check, and why
- Run the hot tap at the sink first — Starting with hot water shows whether the problem is heating or simply cold supply.
- Reset the dishwasher — Breaker off or unplug for a minute, then restore power.
- Look at the element once it is cool — A blister, a crack or a burnt patch along it is a clear sign.
- Check the rinse aid — An empty dispenser makes drying worse, but it does not cause a heating code.
Owner steps, with tools and time
- Hot tap first — Run the kitchen hot tap until the water is hot before starting the dishwasher.
About 2 min
- Reset — Switch off the breaker or unplug the dishwasher for a minute, then restore power.
About 2 min
- Inspect the element — With the dishwasher off and cool, look along the element in the tub floor with a flashlight.
Tools: flashlightAbout 5 min
- STOP before touching the element terminals — They are reached from under the tub, beside live wiring; testing them is technician work.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never bypass the door switch or the float switch: they stop the pump and heater from running in unsafe conditions.
When this is a service call
Call when the code returns after a reset, when the element looks damaged, or at once if there is a burnt smell. Testing the element, the high-limit thermostat and the thermal fuse means working under the tub with the power off, and a tripped safety part needs its cause found before it is replaced.

Generalized information
This is generalized information: it reads F4E2 the way Amana documents it for Amana dishwashers with an electronic control that reports codes in this form. It does not apply to Amana dishwashers with dial-only controls, which flash lights rather than codes, or sister brands on the same platform, whose lists can read differently. No model-specific page for F4E2 exists yet; when one does, it is the more specific answer for that model line.
