# Dishwasher error code i40

### 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](/services/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](tel:+13056155496) and describe what the panel is doing before booking anything.

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