Frigidaire Dishwasher Heating Element: Causes
A Frigidaire dishwasher heating element does two jobs — warming the wash water and radiating heat through the dry phase — so a failed one shows up as cold water, wet dishes, or both. Two multimeter readings settle it, and the element is retained from underneath the tub, which means most installations do not need the…
Safety. The element runs on 120V. Kill the breaker and confirm zero volts before touching a terminal, because an element that has broken down internally can energise the tub and the frame around it.
Two tests that cost nothing#
Heat test. Run a Normal cycle for 20 minutes, then open the door carefully. A working element leaves the water hot and the bottom of the tub warm to the touch. Cool or lukewarm means it is not heating. On Gallery models the display may report the i60 error code, which is the heater circuit specifically.
Glow test. Open the door during the heated dry phase near the end of a cycle. A healthy element ring glows dull orange-red. No glow with the dry indicator lit is a failed element. This test only works during dry — in the wash phase the water absorbs the heat and many elements never visibly glow.

Confirming it electrically#
Turn the breaker off, take the kick plate off (2 Phillips screws) and find the two terminal posts protruding through the tub floor near the front centre, with spade connectors on them. Pull both connectors off and set the meter to ohms.
| Test | Healthy reading | What a bad reading means |
|---|---|---|
| Across the two element terminals | 10 to 30 ohms, depending on model and wattage | OL or infinity means the element wire has burned through |
| Each terminal to the bare metal frame | OL, infinity, on both | Any resistance means the insulation has failed and the element is shorting to the tub |
The second test is the one that matters most. A ground-faulted element can energise the whole dishwasher frame and will trip a breaker; it is not a repair to postpone.
Getting the old ring out#
Frigidaire retains the element with a nut and grommet at each terminal post: the rubber grommet seals the tub floor and the nut clamps it. Back both nuts off with pliers or a wrench and the grommets decompress and let go. Push the terminals up through the floor, then open the door and work the ring out of its groove from inside the tub, easing it past the filter housing and the spray arm hub. It needs bending and angling. If scale has bonded it down, rock it gently side to side — never lever against the tub, which gouges plastic and scratches stainless.
Clear scale and debris from around the holes, pull out any grommets left behind, and check the tub surface where the ring seats.
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.

Fitting the new one#
Feed the element in through the door, settle the ring in its groove and push the posts down through the holes. From underneath, fit fresh grommets — old ones do not reseal — then the retaining nuts, snug and even so the grommets compress uniformly. Overtightening cracks grommets and stresses the tub around the holes.
Reconnect the spade terminals firmly, restore the water, and run a fill cycle while you watch the penetrations from below with a torch. Any drip means a quarter turn more on the nuts. Only once it is dry down there should the breaker go back on. Then run a Normal cycle, check for heat at 20 minutes, and confirm the dishes come out dry.
Why elements die early#
Hard water is the main culprit: scale insulates the element surface, creates hot spots and cooks the resistance wire from within. A monthly vinegar cycle genuinely slows this down. The other two causes are a dry run, where a failed fill valve or stuck float lets the element energise with no water, and voltage spikes damaging the internal wire.
Cracked tub floor, arced terminals, or an element that tests fine while the heater still does nothing? That last one points at the control board relay — book a diagnostic rather than replacing parts on spec.
