JennAir dishwasher F1E1 error code
F1E1 does not mean the same thing on every JennAir dishwasher. Our data shows 2 documented meanings, depending on which engineering platform the model is built on. Look up your model number to see the one that applies.
| Meaning | Appliance | JennAir models |
|---|---|---|
| Control: pilot relay stuck on | Dishwasher | 11 |
| Control: ACU relay or triac failure | Dishwasher | 3 |
F1E1: Control: pilot relay stuck on
- Brand

- Appliance
- Dishwasher
- Code
- F1E1
- Documented meaning
- Control: pilot relay stuck on
- Applies to
- 11 JennAir models on 1 platform
- Can you keep using it?
- No — stop and have it checked
F1E1 means the main control found that its pilot relay, which feeds power to several of the dishwasher's loads, stayed closed when it should have opened.
What the dishwasher is detecting
The control watches the state of the relay it uses to switch power to the dishwasher's loads. If power is still present after the relay has been told to open, the control stores this code, because it can no longer reliably switch those loads off.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A relay on the main control that has stuck closed.
- Documented A shorted load (for example a valve, pump or heater) on the relay's circuit that damaged the relay; the documentation has the technician check every load on that relay before fitting a new control.
Safe checks you can make
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
- Note whether the code comes back right after a power reset or only after some cycles; that detail helps the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks every component powered through the pilot relay for a short before any control is replaced, so a new control is not damaged by the same fault.
- Confirms whether the control is the part at fault.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Stop using the dishwasher and switch off its breaker. A relay stuck closed means the control may not be able to switch loads such as the heater off.
JennAir models documented with this code
F1E1: Control: ACU relay or triac failure
- Brand
- JennAir
- Appliance
- Dishwasher
- Code
- F1E1
- Documented meaning
- Control: ACU relay or triac failure
- Applies to
- 3 JennAir models on 1 platform
- Can you keep using it?
- No — stop and have it checked
F1E1 means the main control (ACU) detected a failure in one of its own switching parts, a relay or triac that turns a load on and off.
What the dishwasher is detecting
These controls check the supply and current of selected loads as they switch them. When a relay or triac on the main control does not behave as commanded, this code is stored, often together with the code for the affected load.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A relay or triac failure on the main control board.
- Documented Current leaking to ground from a load such as the heater, wash motor or a valve (named on the 2023 platforms).
Safe checks you can make
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
- Note whether the code comes back right after a power reset or only after some cycles; that detail helps the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Reviews the code history: the documentation uses this code together with heater, wash motor and fill codes to decide whether the control or the load is at fault.
- Checks the loads for leakage to ground before replacing the control.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher main control board replacement | $260–$590 | Moderate |
| Dishwasher heating element or drying fan replacement | $190–$410 | Moderate |
| Dishwasher circulation pump and wash motor replacement | $300–$620 | Heavy |
| Dishwasher water inlet valve replacement | $180–$360 | Light |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Stop using the dishwasher until it is checked. A control that cannot switch loads reliably may leave a valve or heater on.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F1E1 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
