Kenmore Dishwasher 7-1 / F7E1 Error: Heating Element Does Not Work
The kenmore dishwasher 7-1 / f7e1 error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Dishwasher Error Code 7-1 / F7E1 Mean? Error code 7-1 — also displayed as F7E1 — on Kenmore HE dishwashers means the heating […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. The dishwasher will complete cycles using cold or lukewarm water — the pump and spray arms still function. However, cleaning performance is significantly degraded, grease will not be removed effectively, and sanitization is not achievable. Repair within a few days.
Can I reset the code?
No. F7E1 reflects a confirmed heater circuit failure. A reset clears the display code but the underlying failure — element, wiring, or board relay — remains and F7E1 returns on the next cycle where the heater is called.
When to stop immediately?
Stop if you notice: Element tests open (OL) on multimeter — replacement needed before further cycles, Wire connectors at element terminals are melted or badly corroded.
Symptoms You May Notice
Dishwasher displays 7-1 or F7E1 during or at the end of the wash cycle
The code sets when the control board activates the heating element but the thermistor confirms that water temperature did not rise within the required time window — distinguishing it from a sensor fault (3-1) because the heater circuit is the confirmed unresponsive component.
Dishes are not hot to the touch at the end of the drying phase
Both the wash-water heating and the drying cycle heating rely on the same element; a failed element leaves dishes cool and wet at cycle end, with visible moisture or water pooling in concave surfaces like cups.
Sanitize LED does not illuminate at cycle completion even when the Sanitize option was selected
The sanitize confirmation LED requires the wash water to have reached 150°F. With a failed heating element, this temperature is never achieved and the sanitize indicator remains off, confirming the heating failure.
Interior door and tub walls feel cool to the touch after a cycle
A working dishwasher leaves the stainless interior warm enough to feel through bare hands at cycle end; if the walls and inner door panel feel room temperature or cold, the heating element never raised tub temperature during the wash or dry phase.
Possible Causes
Open-circuit heating element
The resistance wire inside the stainless heating element loop has burned through, creating an open circuit. This is the most common cause of F7E1 on Kenmore 665 HE models and is confirmed with a multimeter showing OL (open) resistance instead of the expected 10–30 ohms.
DIY PossibleLoose or burned wiring connection at the heating element terminals
The push-on wire connectors on the element's two terminals can corrode or melt from heat exposure, creating an open circuit in the heater wiring path without the element itself failing.
DIY PossibleFailed heater relay on the main control board
The relay that switches 120 V to the heating element has failed open on the control board, so the element receives no power even though it is electrically intact. A technician confirms this by measuring voltage at the element terminals during a cycle.
Requires ProfessionalSafe Checks You Can Do
-
1
Test the heating element for continuity and resistance
Unplug the dishwasher and remove the lower rack. Locate the heating element terminals at the back of the tub floor — two push-on connectors on the element's legs. Disconnect both wires and set a multimeter to resistance. Touch the probes to the two element terminals. A reading of 10–30 ohms is healthy; an OL (open) reading confirms element failure.
Also inspect the wire connectors visually — look for melted plastic or black discoloration around the terminal ends, which indicates a poor connection that burned rather than the element wire failing internally.

Check the wiring connections at the element terminals
With power off, firmly push the two wire connectors back onto the element terminals (they should snap on securely). If either connector slides on loosely rather than gripping, the terminal or connector has burned out and the wiring harness end needs replacement. Restore power and run a short hot-water cycle to verify whether F7E1 clears.
A loose terminal connection causes arc damage that can eventually char the surrounding plastic tub — inspect the tub floor near the element legs for discoloration if the connection appears burned.
When to Call a Professional
Contact a qualified technician if:
- Element measures correct resistance but code persists — board voltage output to element must be measured under power by a technician
- Heater relay on control board has visible burn marks or pitted contacts
- Element terminal area shows tub discoloration suggesting ongoing arcing
