What we can confirm
Code i40, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
i40
The machine is asking to be cleaned, and it is the code most worth acting on early because what it prevents is the drain repair. The filter and the glass trap sit at the bottom of the tub and take the soil the spray arms wash off; when they load, the water the pump is trying to move carries the rest of it into the sump. Rinsing plates before loading does not help here — modern detergents need something to work on — but pulling the filter twice a year does.

What it narrows down to
Error code i40 indicates a clogged filter or sump. This occurs when food soils have built up in the sump.

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Error Code i20 indicates that the dishwasher is not draining properly.
Error Code Hd or HO indicates the unit is in the "Heat Delay" or "Heater On" mode. This delay is to allow the dishwasher to heat the water to the optimal temperature.
Error Code 01-24 indicates that the delay option has been enabled and will begin the cycle once the displayed time reaches 0.

What i40 means on this make
The machine is asking to be cleaned, and it is the code most worth acting on early because what it prevents is the drain repair. The filter and the glass trap sit at the bottom of the tub and take the soil the spray arms wash off; when they load, the water the pump is trying to move carries the rest of it into the sump. Rinsing plates before loading does not help here — modern detergents need something to work on — but pulling the filter twice a year does.
Where this appears, and why not to clear it
On the appliance's own display, as a short single code — a letter and a number, or two letters. Nothing alternates and nothing arrives in halves on this make, so what the panel shows is the whole of it. Photograph it before you cut the power. This maker's own answer to most of these is thirty seconds at the breaker, and that is worth following once — but a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again.
What to do about it
- Pull the filter assembly out of the sump. It twists free by hand on these machines and needs no tools.
- Rinse it under a running tap and clear the glass trap underneath it while it is out.
- Look at the sump itself for anything solid — a seed, a chip of glass, a label off a jar.
- Run the machine empty on a hot cycle before judging whether the code has gone.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 615-5496 and describe what the panel is doing before booking anything.
