Whirlpool Dishwasher: Replace Heating Element
If your Whirlpool dishwasher leaves dishes cool and wet, never lights the sanitize indicator, or stretches cycles waiting for heat that never comes — sometimes logging F3E1 or F3E2 — the heating element has likely failed. Plan on 45 to 60 minutes; the wiring is simple, but pulling the machine out to reach the element…
Where the element lives#
The element is a ring-shaped resistance coil seated in the floor of the tub, with two terminals that pass through the tub bottom and are reached from underneath the dishwasher. F3E1 and F3E2 point at the thermistor circuit, which an element short can drag down, so confirm the element itself before you blame the sensor.
Safety warning: Disconnect power at the circuit breaker. The heating element connects directly to 120V through the control board relay. A failed element can create a ground fault hazard. Test for zero voltage before touching element terminals.
What you need#
| Category | Detail |
|---|---|
| Tools | Torx T20 driver, quarter-inch hex nut driver, adjustable wrench, multimeter, needle-nose pliers, towels, moving blanket |
| Part | Model-specific heating element plus its terminal grommets or gasket if not supplied with the element |
| Time and level | 45 to 60 minutes, Advanced (unit must come out) |

Step by step#
1 - Cut power and water. Switch off the dedicated breaker and close the hot-water valve under the sink. Open the door, cancel any running cycle, and give a recently used element a few minutes to cool.
2 - Drop the lower access panel. Remove the hex screws at each end of the kick plate and lift it away. The underside terminals now sit in view where the element pokes through the tub floor.
3 - Read the element with a meter. Pull both spade connectors straight off — you cannot test accurately with them attached. On the ohms range a healthy element reads about 10 to 30 ohms; an open reads OL; a near-zero reading means it is shorting. Then check each terminal against the tub metal: any continuity to ground is a shock and fire hazard and condemns the element.
4 - Pull the machine out. Open the door, back out the two Torx T20 countertop screws at the top edge, then close it. Release the drain hose under the sink, disconnect the supply line at the inlet valve, and ease the unit forward onto a blanket or cardboard.
5 - Tip it back for access. With every connection free, lay the dishwasher back to roughly forty-five degrees, propped or held, so the underside of the tub and the element retaining hardware face you.
6 - Free the mounting hardware. The terminals pass through rubber grommets and are held either by a lock nut on each post or by a single bracket across both. Back off the nuts or the bracket screws so the element is loose.
7 - Lift the element from inside. Stand the machine up, open the door, take out the lower rack and the lower spray arm (twist its nut counterclockwise), and push the freed terminals up through the tub floor so the coil lifts clear. Note the grommets — they seal the holes and either transfer over or get replaced.
8 - Inspect and clean. Check the grommets; if they are cracked, brittle or crushed flat, fit new ones. Scrub mineral scale and corrosion from around the tub holes so the new seal seats clean.
9 - Set the new element. Feed the new terminals through the grommets, press the grommets into the tub-floor holes from inside, and settle the ring flat against the floor without letting it touch the spray-arm hub or any plastic.
10 - Secure and rewire from below. Tip the machine back again. Thread the lock nuts (or refit the bracket) and snug them just until the gasket compresses — overtightening warps the tub floor. Push each spade connector firmly back until it clicks, and confirm neither terminal touches the tub.
11 - Reinstall the dishwasher. Slide it home, reconnect the supply line and drain hose, drive the Torx T20 countertop screws, refit the kick plate, and replace the spray arm and rack.
12 - Run a heat test. Restore power and start a Normal cycle with Heated Dry. After fifteen to twenty minutes, press Pause and crack the door — warmth and steam mean the element is heating. Let the full cycle finish, check underneath for leaks at the grommets, and if you had F3E1 or F3E2 stored, clear them in diagnostic mode.
If something is off after the swap#
- No warmth at all: reseat the spade connectors and listen for the board relay clicking into the heat phase; a silent relay means the board itself needs replacing.
- A leak at the terminals: the grommet is not sealing — dry the area, add a quarter turn to the lock nut, and replace the grommet if it still weeps.
- Breaker trips at the heat phase: the new element is shorted to ground or a wire is touching the tub. Cut power and recheck terminal-to-tub isolation on the meter.
- Dishes still not clean: heat alone is not the cure — inspect the spray-arm nozzles and the filter stack.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

When to call a professional#
Get help if the element shorted and took the control-board relay with it, if the built-in is too heavy to tip safely without a second person, if the tub-floor holes have corroded through (a tub problem, not an element one), or if making 120V connections is outside your comfort zone.
