What we can confirm
Code i20, 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
i20
The machine could not empty itself, and the maker's own list starts where we would: with the knockout plug in the garbage disposal. In a kitchen fitted to a schedule that plug is left in often enough to be the first suspect, and a machine that has never drained properly since the day it was installed is describing that rather than a failure. After the disposal come the hose, its height and the filter — three checks that cost nothing and settle most of these before a part is discussed.

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 i40 indicates a clogged filter or sump. This occurs when food soils have built up in the sump.
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 i20 means on this make
The machine could not empty itself, and the maker's own list starts where we would: with the knockout plug in the garbage disposal. In a kitchen fitted to a schedule that plug is left in often enough to be the first suspect, and a machine that has never drained properly since the day it was installed is describing that rather than a failure. After the disposal come the hose, its height and the filter — three checks that cost nothing and settle most of these before a part is discussed.
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
- If the machine is newly installed, check the knockout plug was removed from the disposal. The maker lists it first and so do we.
- Look at the drain hose along its whole run for pinching, and check the high loop — the maker asks for a minimum of thirty-two inches from the floor.
- Pull the filter and the glass trap out of the sump and clean them. Food soil there restricts the drain before it blocks it.
- Reset by holding cancel, or by cutting power for three minutes. A code that returns after a clear path is the pump rather than the plumbing.
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.
