The short answer
These codes are paired with leaks or drips on the cabinet or floor. The door gasket is the place to start, and not only because it is the commonest source: it is the only one you can inspect completely without a tool, in a minute, with the machine open in front of you.
Whirlpool dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| 6-1, 6-3 | Loaks or Drips on Cabinet or Floor |
What you observe alongside the code
- Water on the floor in front of the machine — The commonest presentation, and the least informative about the source.
- A damp cabinet side or a swollen kick board — Water that has been tracking for a while.
- Drips only during the wash, not the drain — Points at the door or the spray system rather than the drain path.
- Water in the base pan with a dry floor — The pan catching it, which is how leaks are usually caught early.
What triggers it, most likely first
- A worn or dirty door gasket — First: the seal takes the whole pressure of the wash against it, and a food deposit or a flat spot at a corner is all it takes to weep on every cycle.
- An overfill reaching the door seal — Last: a fill fault presenting as a leak, and it is worth ruling out before any seal is replaced.
- A loose hose clamp at the pump or sump — Second: clamps relax with heat cycling, and the joints sit low so the water goes straight to the base.
- A cracked or perished spray-arm feed or fill hose — Third: it leaks only when pressurised, which is why it shows during the wash and not at rest.
Check in this order, and why
- Run a finger round the whole gasket, including the bottom corners — A deposit or a flat spot is visible and free to find.
- Dry everything and lay paper down before running anything — Paper shows you where the first drop lands and how fast.
- Run a short cycle with the toe panel off and watch the front corners — The single most informative test available to an owner.
- Check the door gasket all the way round by hand — Feel for flat spots and deposits, especially at the bottom corners.
Clearing the code, then the owner-safe checks
- Bail and dry the tub, then dry the floor and base pan — Everything below is easier and more informative dry.
Tools: sponge, towelsAbout 20 min
- Clean the door gasket and the door edge it seals against — Food deposits at the bottom corners are the commonest single cause.
Tools: clothAbout 15 min
- Run a short cycle with the toe panel off and watch — Note which corner and at which stage the water arrives.
Tools: screwdriver, flashlightAbout 30 min
- STOP HERE if water arrives from under the tub — That is a sump or pump seal, and the machine has to come out.
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.
When this code is a service call
Call when the water arrives from beneath the tub rather than from the door or a visible hose joint: sump and pump seals need the machine drawn out and laid over. Call promptly in any case if the floor is wood or laminate, because the flooring outruns the appliance repair in cost within days.

Which model lines this reading applies to
This reading of 6-1, 6-3 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.
