The short answer
This code is paired with melted dishware or a melted spray arm. Nothing in a normal cycle is hot enough to melt a dishwasher-safe item in the rack — melting happens where something has come to rest against the heating element in the tub floor. Find the item and clear the element before running anything else.

What you observe alongside the code
- A plastic item deformed or holed on one face — The face that was against the element.
- A smell of hot plastic during or after the cycle — Often the first thing anyone notices.
- Melted residue on the element or the tub floor — Where the item came to rest.
- A spray arm that no longer turns freely — Softened or fouled by melted plastic.
What triggers it, most likely first
- A light item fallen through the rack onto the element — First: lids, small containers and utensils are light enough to be moved by the spray, and the element is what they land on.
- A non-dishwasher-safe item in the lower rack — Second: the lower rack sees the hottest water and the closest proximity to the element.
- Overloading, so items shift during the wash — Third: a rack packed past its capacity lets things move, and moving items fall.
- A damaged or missing rack tine — Fourth: a broken tine is a gap, and a gap is where things fall through.
Check in this order, and why
- Look at the heating element in the tub floor first — Whatever melted is almost certainly resting on it or has left residue there.
- Find the melted item and where it came to rest — It answers the question in almost every case.
- Check the element for residue before running anything else — Melted plastic on an element smokes on the next cycle.
- Look for broken or missing rack tines — A gap explains a repeat of the same accident.
Clearing the code, then the owner-safe checks
- Let the machine cool completely, then remove the melted item — Plastic on a hot element is both a burn and a fume risk.
Tools: glovesAbout 20 min
- Scrape cooled residue off the element carefully — Plastic, not metal, against the element sheath; do not gouge it.
Tools: plastic scraperAbout 20 min
- Check and clear the spray arms and the filter — Fragments travel and block holes.
Tools: toothpickAbout 15 min
- STOP HERE if residue is baked hard onto the element — Forcing it risks holing the sheath, which is an electrical fault waiting to happen.
Before you open anything
Safety
Unplug the dishwasher or switch off its breaker before removing the toe panel or the inner door panel. A capacitor can hold a charge after the power is off, and the supply is not switched at the door. Bail any standing water out of the tub before working underneath, and go into the sump with gloves and a light — broken glass collects there. Melting plastic gives off fumes: open a window, and do not run another cycle until the element is clear. A gouged element sheath is an electrical hazard, not a cosmetic one.
When this code is a service call
Call when residue is baked hard onto the element or the sheath looks damaged, because a compromised element in a tub full of water is an electrical fault rather than a mark. Call too if the element seems to be running hotter than it should on a load that was correctly packed, which is the one version of this that is an appliance problem.

Which model lines this reading applies to
This reading of 3-1 applies to Whirlpool-built built-in dishwashers of the generation whose service documentation publishes this code, which is where the manufacturer documents it. A machine with a mechanical timer and no diagnostic display does not produce it, and the same characters can be published against a different fault on a KitchenAid or Maytag-badged unit from the same platform. Some machines on this platform have a concealed element that nothing can rest on, which makes this fault a loading problem only on the exposed-element families.
