The short answer
In the service troubleshooting table this code is paired with poor drying, which is a symptom rather than a failed part. Start with rinse aid and loading: between them they account for most complaints about a dishwasher that washes well and dries badly. Only when the tub is cold at the end of a cycle does this become a heater question.
Whirlpool dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| 1-1 | Poor Dry |
What you observe alongside the code
- Plastics wet while china and glass are dry — The classic signature: plastics hold no heat to evaporate with.
- Pooled water in upturned cup bases — A loading problem rather than a drying one.
- Everything uniformly damp — Points at the heat or the rinse aid rather than at loading.
- Streaks and beads rather than sheets of water — Rinse aid empty or set too low.
What triggers it, most likely first
- Rinse aid empty or set too low — First: without it water beads and clings instead of sheeting off, and no amount of heat dries a beaded surface well.
- Plastics and light items in the load — Second: they store almost no heat, so they cannot evaporate their own surface water the way china does.
- The door opened too soon after the cycle — Third: the last of the drying happens in the closed, hot tub, and opening it early vents exactly the heat that would have finished the job.
- A weak or failed heating element or vent fan — Fourth: the real hardware causes, and they affect the whole load rather than just the plastics.
Check in this order, and why
- Check the rinse aid level and setting before anything else — It is free and it is the cause in most households.
- Check the rinse aid reservoir and its setting — Free, and it is the cause in most households.
- Notice whether only plastics are wet — Plastics-only is normal behaviour, not a fault.
- Leave the door shut for a while after the cycle ends — The last of the drying happens in the closed tub.
Clearing the code, then the owner-safe checks
- Fill the rinse aid reservoir and raise its setting a step — The single most effective change available.
About 5 min
- Reload so nothing nests and nothing traps water — Angle bowls and cups so water runs off rather than pooling.
About 10 min
- Leave the door closed for a while after the cycle finishes — Then crack it open to let the steam out.
About 20 min
- STOP HERE if the tub is cold at the end of a cycle — That is the heater or its relay, under the tub.
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. The heating element in the tub floor stays hot after a cycle, so keep hands clear of it when unloading.
When this code is a service call
Call when the tub is cold at the end of a cycle with rinse aid full and the load sensibly packed, because that points at the heating element, its relay or the temperature sensor. Poor drying on its own is never urgent — the machine is washing correctly, and the cost of waiting is a tea towel.

Which model lines this reading applies to
This reading of 1-1 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. Drying systems differ across this platform — some condense, some use a vent fan — and which one you have changes what a heater fault looks like.
