# Dishwasher error code i40

### What i40 means on this make

The only one of this make’s three dishwasher codes that reports an actual failure, and the fix is maintenance rather than parts. The sump is the well under the lower rack where water collects before the pump takes it, and the filter and glass trap sit in it to keep solids out of the impeller. When they load up, the machine cannot move water fast enough and says so. What fills them here is worth naming: rinse-free modern detergents and scraping less than people used to, plus the hard water this county runs on, which leaves scale that holds everything else.

### 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 lower rack and lift out the filter assembly — on these machines it twists out by hand with no tools.
- Clear the glass trap, which is the flat plate beside the filter, and rinse both under a hot tap. The maker names the glass trap specifically.
- Look into the empty sump for standing water. Water still sitting there with the filter out points past the filter, at the pump or the drain hose.
- Refit both properly — a filter that is not fully seated lets solids straight through — and run a cycle empty before judging it.

### 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) 912-9018](tel:+13059129018) 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; try cleaning out the glass trap and re-run the unit.
